12 Best n8n Alternatives for Autonomous AI Agents (2026)

The best n8n alternatives for autonomous AI agents are HostAgentes Paperclip and OpenClaw — agent runtimes with persistent memory, reasoning loops, and per-agent token budgets that n8n's DAG model can't express. For classic workflow automation, the strongest n8n alternatives are Windmill, Activepieces, and Pipedream for developers, Make and Zapier for no-code teams, and Langflow or Flowise for visual LLM apps. n8n is excellent at deterministic workflow automation; agents are a different programming paradigm entirely — they reason, decide, iterate, and remember. This guide ranks all 12 alternatives and tells you exactly when keeping n8n is the right call.

Top 12 n8n alternatives & competitors (2026)

The 12 tools teams actually switch to from n8n, at a glance. For deterministic workflow automation the alternatives below compete on price and editor; for autonomous AI agents, only an agent runtime can replace n8n's missing reasoning layer.

First-hand note: HostAgentes operates Activepieces and Langflow as managed hosting products in production — our notes on those two come from running them daily at scale, not from a demo. The other ten are assessed from public docs and listed pricing, September 2026.

The 12 best n8n alternatives, ranked

Quick verdicts above, the detail on each tool below: what it is, how it differs from n8n, and when to pick it instead.

1. HostAgentes Paperclip — best n8n alternative for autonomous AI agents

Paperclip is a managed agent runtime, not a workflow editor. Agents are persistent processes with cross-session memory, native reasoning loops, per-agent token budgets, and multi-agent orchestration. Where n8n executes a graph you drew in advance, a Paperclip agent computes its own path at runtime — observe, decide, act, repeat — and stays running between invocations. Managed from $15/mo with zero infrastructure to maintain.

Pick it over n8n when: the agent itself is the product and it has to keep running, remember, and reason — not just execute fixed steps.

2. HostAgentes OpenClaw — best budget BYOK agent hosting

OpenClaw runs the same agent-first paradigm with bring-your-own-key LLM access: each agent gets an isolated key context, keys rotate independently, and your model bill goes straight to your provider instead of through a markup. From $3.99/mo — less than n8n Cloud's entry plan, with agent memory, auto-restarts, and agent-level monitoring included instead of execution caps.

Pick it over n8n when: you want real agents at hobby or side-project budgets, without n8n's execution caps or a separate server bill.

3. Windmill — best code-first workflow engine

Windmill turns scripts in Python, TypeScript, and Go into shareable workflows with a UI, schedules, and permissions on top. It's the standing pick in developer comparisons when you want n8n-style ergonomics but real code instead of nodes. Open-source with a paid cloud.

Pick it over n8n when: your team outgrew visual editors but still wants workflow infrastructure around code.

4. Activepieces — closest open-source feel to n8n

Activepieces is a visual builder with a genuinely open-source license (n8n is fair-code, not OSI-approved) and a growing pieces ecosystem that feels immediately familiar to n8n users. HostAgentes operates Activepieces as managed hosting in production — it's the migration path we most often recommend for teams leaving n8n's visual editor behind.

Pick it over n8n when: you want n8n's mental model under a true open-source license, self-hosted or managed.

5. Make — best visual no-code step up

Make (formerly Integromat) offers branching logic, iterators, and error handlers that go deeper than Zapier, with a visual canvas n8n users adapt to quickly. Freemium SaaS, operations-based pricing.

Pick it over n8n when: you want visual automation with more depth than Zapier and zero self-hosting.

6. Zapier — biggest integration catalog

Zapier's 8,000+ app catalog remains the widest in the category, and setup is the fastest anywhere. Its AI agents sit on top of the same Zap model. Freemium SaaS.

Pick it over n8n when: breadth of SaaS glue matters more than cost per operation or self-hosting.

7. Pipedream — developer integration platform

Pipedream combines thousands of pre-built, managed-auth API connectors with inline Node.js, Python, Go, or Bash steps — workflow-shaped, event-driven, credit-priced. It occupies the middle ground between Zapier's no-code and Windmill's full code-first model.

Pick it over n8n when: your team lives in code but wants managed OAuth, connectors, and hosting handled for you.

8. Langflow — best visual LLM app prototyping

Langflow is an open-source drag-and-drop builder for LLM apps and RAG pipelines — compose models, prompts, retrievers, and vector stores visually, then expose the flow as an API. HostAgentes operates Langflow as managed hosting in production.

Pick it over n8n when: the artifact you're building is an LLM application or RAG flow, not a business-logic workflow.

9. Flowise — best open-source visual LLM flow builder

Flowise covers chatflows, agent flows, and RAG pipelines in an open-source visual editor — the other tool that consistently appears alongside Langflow in n8n-alternatives lists for AI work. Free to self-host; managed instances start at $9.99/mo on HostAgentes with unlimited predictions included.

Pick it over n8n when: you want an open-source visual builder purpose-made for LLM chatbots and agent flows.

10. Node-RED — lightweight event-driven veteran

Node-RED is the flow-based automation veteran, backed by the OpenJS Foundation, with an unmatched hardware/IoT and event-driven ecosystem. Free, open-source, runs on modest hardware.

Pick it over n8n when: your automation lives close to devices, MQTT, or edge hardware.

11. Kestra — declarative YAML orchestration

Kestra defines pipelines as versioned YAML with a UI on top — infrastructure-as-code discipline for scheduled, data-engineering-flavored workflows. Open-source with a paid cloud.

Pick it over n8n when: your workflows are scheduled data pipelines that belong in Git, not in a canvas.

12. n8n (baseline) — when keeping n8n is the right call

Honest ranking includes the incumbent: for deterministic trigger-to-output plumbing, n8n is still excellent, self-hosting is free, and the cloud has a free tier (paid from ~$24/mo, verified September 2026). Its September 2026 repositioning as an "AI workflow automation platform" ships node-level AI — useful inside the DAG, but the execution model remains a fixed graph.

Keep n8n when: every step is known in advance — and pair it with an agent runtime (the hybrid pattern below) when reasoning enters the picture.

Best free & open-source n8n alternatives

If you specifically want an open-source n8n alternative — free to self-host, inspect, and modify — six tools from the ranked list above fit, plus a newer AI-native entrant below. One nuance first: n8n itself is fair-code, not OSI-approved open source. Self-hosting is free and the source is public, but the license doesn't allow offering n8n itself to others as a service. That's exactly why teams go looking for a true open-source alternative.

Open-source pick Self-host Why teams switch from n8n
Activepieces Free The closest true open-source n8n: visual builder, similar mental model, permissive license. Also available as managed hosting on HostAgentes.
Windmill Free The code-first option: real Python/TypeScript/Go scripts with a UI on top. The pick once you outgrow visual editors.
Langflow Free Visual LLM app and RAG pipeline prototyping. Also available as managed hosting on HostAgentes.
Flowise Free Open-source visual LLM flow builder: chatflows, agent flows, RAG pipelines. Also available as managed hosting on HostAgentes.
Node-RED Free The veteran: lightweight, flow-based, huge hardware/IoT and event-driven ecosystem, backed by the OpenJS Foundation.
Kestra Free + paid cloud Declarative YAML pipelines with version control — infrastructure-as-code discipline for scheduled workflows.
Sim Free + managed cloud AI-native open-source agent workflow builder: per its maintainers, native agent memory, multi-model orchestration, and MCP support — a 2026 entrant with its own community momentum.

The community has opinions too. On r/AiAutomations, the top-voted advice for AI-agent builds is blunt — "forget Appsmith, Buildship, n8n, Retool, Zapier, Budibase" — because workflow canvases bolt agents on rather than run them. GitHub's n8n-alternative topic and two of the most-shared videos of 2026 (a 100%-open-source Sim walkthrough and its LinkedIn follow-up) mark the open-source wave this table reflects. The pattern underneath all of it: people swap n8n for a different workflow editor, or leave the workflow paradigm entirely for an agent runtime.

And if what you want is something simply better than n8n for AI agents — not a workflow tool at all — that's the agent-runtime question. No open-source workflow engine closes the five gaps below (persistent memory, reasoning loops, token budgets): those need a purpose-built agent runtime like Paperclip or OpenClaw.

Self-hosted tiers are free software; you run the server, backups, and updates. HostAgentes operates managed hosting for Activepieces and Langflow in production — everything else on our stack is either our own runtime or assessed from public docs, September 2026.

Two different programming paradigms

n8n is a DAG executor. You define nodes and edges at design time, and at runtime n8n traverses that graph in order: trigger fires, step A runs, step B runs, output goes to C. The path is always the one you drew. This is deterministic automation and n8n does it well — it's the same model as Zapier, Make, or a shell script, with a much better visual editor.

Autonomous AI agents work differently. You give the agent a goal and a set of tools. The agent enters a reasoning loop: observe the situation, decide which tool to call next, call it, observe the result, decide again. This continues until the goal is met or the agent determines it cannot proceed. The path through the problem is computed at runtime, not drawn at design time. You cannot build this loop inside n8n's DAG model without significant architectural gymnastics — and even then you're fighting the tool's assumptions.

Which n8n alternatives support MCP (Model Context Protocol)?

MCP has become the standard way for AI agents to call external tools, so it's a fair filter when comparing n8n alternatives. The table below maps each tool's MCP support as documented by its own vendor in September 2026. Read it as connection-layer information: a workflow exposed over MCP is still a predefined DAG — MCP lets agents reach these tools, it doesn't turn any of them into an agent runtime.

Tool MCP support (per vendor docs, Sep 2026) What it means in practice
Zapier First-party hosted MCP server (mcp.zapier.com), Streamable HTTP; classic and agentic tool modes Expose selected Zapier actions as tools any MCP client can call
Make First-party hosted MCP server; scenarios become callable tools; an MCP client is also built in AI calls your scenarios as structured tools; scenarios can call external MCP servers
Pipedream Dedicated first-party MCP server covering its 3,000+ integrated apps Managed auth for 3,000+ apps exposed to any MCP client
Activepieces Built-in MCP server per project; assistants can build flows, manage tables, and test runs MCP clients can operate the builder itself, not just run flows
Windmill Native MCP support; scripts and flows exposed as tools via token or OAuth URL Code-first workflows become per-script MCP tools with folder scoping
Langflow MCP server and client — each project exposes its flows as MCP tools Visual LLM flows are callable by Claude, Cursor, and other MCP clients
Kestra First-party MCP server (api.kestra.io) serving plugin schemas, blueprints, and docs AI coding agents get live Kestra context; separate Python MCP server for its AI Agents
Flowise MCP client node — connects flows to external MCP servers (stdio, SSE, HTTP) Agents inside Flowise can use external MCP tools; no first-party server
n8n (baseline) Native: MCP Server Trigger plus MCP Client nodes Workflows exposed as tools — still a fixed DAG behind the protocol
Sim Per its maintainers: MCP support in this 2026 open-source entrant Agent-workflow builder pitching MCP alongside memory and orchestration
Node-RED Community node only (node-red-contrib-mcp-server); no first-party support Possible, but you're relying on a community contribution, not the core project

MCP support as documented by each vendor, September 2026 — verify current status with the vendor before committing. The pattern: first-party MCP servers are now table stakes for workflow tools (eight of these eleven ship one; a ninth, Sim, claims it per its maintainers). That makes the hybrid pattern easier everywhere — workflow tools as the agent's hands — but the reasoning still has to live in an agent runtime. Paperclip and OpenClaw are agent runtimes whose agents call tools directly; we make no MCP-protocol claim on this page.

Paperclip vs n8n

Paperclip vs n8n comes down to determinism: n8n runs predefined DAGs, Paperclip runs reasoning loops. Choose n8n when every step is known in advance; choose Paperclip when agents must decide their own steps, remember across sessions, and stay inside token budgets. The reversed verdict — n8n vs Paperclip — is the same answer: n8n is the workflow tool, Paperclip is the agent runtime, and neither does the other's job well. Most production teams run both: n8n triggers, Paperclip reasons.

Dimension Paperclip n8n
Execution model Reasoning loop — agent decides the next step at runtime Fixed DAG — you predefine every step and edge
Persistence & memory Built-in per-agent memory across sessions Stateless per execution; state bolted on via Redis/DB
Iterative loops Native (Reason → Act → Observe cycles) DAG forbids cycles; webhook re-trigger workarounds only
Token budgets Per-agent budgets, enforced with alerts LLM calls unmetered from the workflow's perspective
Monitoring Agent-level: success rate, tool calls, latency Workflow execution logs
LLM keys (BYOK) Native vault, per-agent isolation and rotation Generic credential manager shared across workflows
Best at Autonomous agents and multi-agent orchestration Deterministic workflow automation and SaaS glue

Capability comparison as of September 2026, from both products' public documentation and our own production use of Paperclip. See also Paperclip vs OpenClaw for choosing between our two runtimes.

n8n Alternatives for AI Agents: 5 technical gaps n8n can't close

1. No persistent agent memory

n8n is stateless per execution. Each workflow run starts fresh — it has no built-in concept of context that persists between runs. Agents are the opposite: they need to remember previous conversations, tool results, and user preferences across sessions. You can bolt a Redis instance onto n8n and pass state around manually, but you're implementing memory infrastructure the hard way. Paperclip includes persistent vector memory as a first-class primitive; every agent has access to its own context store without any configuration.

2. No reasoning loops — n8n is DAG-linear

ReAct-style agent loops (Reason → Act → Observe → Reason again) require a cycle in the execution graph. n8n's DAG model forbids cycles by design: loops must be implemented with workarounds like webhook callbacks that re-trigger the workflow from outside. This is technically possible but architecturally awkward, slow (round-trips through the n8n trigger layer), and hard to debug. Paperclip's runtime is built around the loop natively — agents reason and act in a tight, monitored iteration without external re-triggering.

3. No per-agent token accounting

LLM calls inside n8n workflows are unmetered from n8n's perspective. You can see execution counts, but there is no concept of a token budget, a per-agent spend limit, or an alert when a particular agent is consuming disproportionate context. For production deployments where dozens of agents are running concurrently, you need that visibility. Paperclip tracks token consumption per agent, per run, and enforces configurable budgets so a runaway agent can't drain your LLM quota.

4. The LLM node is a step, not an orchestration primitive

n8n's AI nodes — including the LangChain integration — treat the LLM as one node in a workflow, equivalent to an HTTP request or a database query. That's appropriate when the LLM is doing a single discrete task (classify this text, extract these fields). It breaks down when the LLM is supposed to be the orchestrator deciding what happens next. Paperclip is built with the LLM as the decision-making center, with tools and sub-agents as its peripherals, not the other way around.

5. No BYOK vault and no agent monitoring

n8n stores LLM credentials in its generic credential manager, which was designed for SaaS API keys — not for managing per-agent LLM API key isolation. OpenClaw on HostAgentes is built around BYOK as a first-class feature: each agent gets its own isolated key context, keys are never logged or exposed in execution traces, and you can rotate them independently. And where n8n shows you workflow execution logs, Paperclip shows you agent-level metrics: task success rates, reasoning depth, tool call frequency, latency per agent — the signals that actually matter for agent operations.

When to use n8n, when to use Paperclip

The honest answer: they solve different problems. Choosing between them comes down to whether you know the steps ahead of time.

Use n8n when the steps are fixed

A Slack message arrives with a support ticket. You extract the subject line, look it up in Zendesk, post the ticket status back to the thread, and write a row to a Google Sheet. Every step is known. The order never changes. The data flows in one direction. This is exactly what n8n was built for — and it handles it with almost no code.

  • → Deterministic trigger-to-output pipelines
  • → SaaS integrations with fixed data shapes
  • → Non-technical teams who need a visual editor
  • → ETL and data sync between services
Use Paperclip when the steps aren't known

A customer sends a message: "I need to migrate our data before Friday's deadline but I'm hitting a rate limit." An agent needs to understand the context, check the account's current plan, look up the rate limit docs, decide if a temporary limit increase applies, draft a response, and maybe open an internal ticket. None of those steps are predetermined. The agent has to reason its way through the problem.

  • + Goals with variable paths to completion
  • + Tasks requiring tool selection at runtime
  • + Multi-session workflows with memory requirements
  • + Multi-agent collaboration on complex tasks
The hybrid approach: n8n triggers, Paperclip reasons

These tools don't have to be mutually exclusive. Many production setups use n8n for the deterministic parts — watching for events, parsing webhooks, routing to the right queue — and call a Paperclip agent via HTTP node when reasoning is needed. n8n does the plumbing; Paperclip does the thinking. You get the visual workflow editor for the structured parts and a proper agent runtime for the non-deterministic parts, without trying to make either tool do what it wasn't designed for.

Cost model: n8n vs HostAgentes

n8n and HostAgentes price on fundamentally different axes. Understanding which model fits your workload matters more than comparing headline numbers.

FAQ — n8n vs HostAgentes

Paperclip vs n8n: which one should I choose?
Whichever order you search — Paperclip vs n8n or n8n vs Paperclip — the decision comes down to execution model. Choose n8n when every step is known in advance: webhooks, data transforms, notifications, approvals. Its DAG editor is mature and its execution-based pricing is cheap for deterministic work. Choose Paperclip when the workload has to reason: a goal where the agent decides which tools to call, keeps memory across runs, and stays running between invocations. The practical pattern most teams land on is both — n8n for plumbing, Paperclip for the reasoning steps, connected over HTTP. One disambiguation: another company's automation app is also named Paperclip (paperclip.inc, an "agentic-native" work tool) and ranks for this exact comparison — it is not the Paperclip runtime compared on this page, which is HostAgentes' managed agent runtime at paperclip.ing.
Doesn't n8n now support AI agents?
Yes at the node level — and the layer matters. In September 2026 n8n repositioned as an "AI workflow automation platform" and its cloud plans now market "workflows and agents" together. Technically, n8n ships an AI Agent node: the reasoning loop runs inside a single workflow execution, memory and tools are configured per node, and the run is bounded by the plan's execution caps. Paperclip and OpenClaw are agent-first runtimes: agents are persistent processes with cross-session memory, per-agent token budgets, agent-level monitoring, and multi-agent orchestration — not steps inside someone else's DAG. Use n8n for deterministic plumbing plus node-level AI; use HostAgentes when the agent itself is the product that has to stay running.
Is Paperclip a replacement for n8n?
Only for the agent-shaped part of your stack. If your n8n workflows are deterministic integrations (webhook in, lookup, post to Slack, done), keep n8n — it is excellent at that. Paperclip replaces n8n where you have been forcing reasoning into the DAG model: LLM decision steps, retry-until-succeeded logic, state passed between runs via external stores. Teams typically end up running both — n8n for plumbing, Paperclip for reasoning — connected over HTTP.
Can n8n run AI agents natively?
Not in the autonomous-agent sense. n8n can call LLM APIs inside a workflow node, but the execution model is still a directed acyclic graph: it runs from start to finish in a fixed sequence you defined at design time. Autonomous agents are different — they receive a goal, enter a reasoning loop, decide which tools to call next, and iterate until the goal is met. That loop is not a concept n8n was built around. If your 'agent' always follows the same steps in the same order, n8n is a reasonable fit. If it needs to reason about which steps to take at runtime, you need a proper agent runtime like Paperclip.
Can I call Paperclip from an n8n workflow?
Yes, and this is actually the hybrid setup we recommend for teams already invested in n8n. Use n8n's HTTP Request node to POST to your Paperclip agent endpoint whenever you need reasoning or autonomous action. n8n handles the trigger logic and data plumbing (webhook arrives, parse payload, forward to agent, store result); Paperclip handles the non-deterministic part (analyze the request, call the right tools, iterate, return a structured response). The two tools complement each other rather than compete.
What is the difference between an n8n LangChain node and Paperclip?
An n8n LangChain node is a single LLM call within a workflow step. It sends a prompt and receives a completion — useful for tasks like summarization or classification inside a pipeline. Paperclip is an orchestration runtime: it manages multiple agents, routes tasks between them, maintains persistent memory across sessions, enforces token budgets, and runs ReAct-style reasoning loops where the agent decides at each step what to do next. The LangChain node is an ingredient; Paperclip is the kitchen.
Which is cheaper long-term — n8n or HostAgentes?
It depends on your starting point. n8n self-hosted is free software, but you pay for the server, SSL, backups, monitoring, and maintenance — typically $20-60/mo in infrastructure plus ongoing developer time. n8n Cloud now has a free tier (verified September 2026) with paid plans from ~$24/mo billed annually — all capped by execution count, so your bill scales with volume. HostAgentes starts at $3.99/mo for OpenClaw (BYOK) or $15/mo for Paperclip, with no execution caps inside plan limits and zero infrastructure to manage. If you already run a server for other workloads, n8n self-hosted can be nearly free. If you're starting fresh and want zero ops, HostAgentes is typically lower total cost.
Can I migrate n8n workflows to Paperclip?
Not one-to-one — they are different paradigms. An n8n workflow is a graph of fixed steps; a Paperclip agent is a reasoning loop with tools. But many patterns translate: the integrations you use in n8n (Slack, Airtable, HTTP calls) map to tool definitions in Paperclip; the trigger conditions you set in n8n become the initial prompt or event hook that starts an agent run. Think of it less as migration and more as reimplementation at a higher level of abstraction.
Does n8n support MCP (Model Context Protocol)?
Yes. n8n ships native MCP support — an MCP Server Trigger that exposes workflows as MCP tools, plus MCP Client nodes that call external MCP servers (verified September 2026). But MCP changes the connection layer, not the execution model: a workflow exposed over MCP is still a predefined DAG that runs the same steps in the same order. MCP standardizes how models reach tools; it does not give a workflow the ability to reason about which steps to take. If your goal is an agent that plans over MCP-exposed tools at runtime, that remains agent-runtime territory.
Which n8n alternatives support MCP (Model Context Protocol)?
Per vendor documentation (September 2026): Zapier, Make, Pipedream, Activepieces, Windmill, Langflow, Kestra, and n8n itself all ship first-party MCP servers; Flowise connects to MCP servers through a client node; Node-RED relies on a community node; Sim claims MCP support per its maintainers. MCP is the connection layer — it exposes workflows as tools an AI agent can call — not an execution-model change: a workflow exposed over MCP still runs a predefined DAG. If you need an agent that reasons over tools at runtime, that's an agent runtime like Paperclip or OpenClaw.
What are the best n8n alternatives for AI agents?
For autonomous AI agents, the leading n8n alternatives are HostAgentes Paperclip and OpenClaw — both run agents with persistent memory, reasoning loops, tool calling, and per-agent token budgets that n8n's DAG model can't express. If you only need to replace n8n's workflow automation (not run agents), Windmill and Activepieces are the closest code-first and open-source equivalents; Langflow suits visual LLM app prototyping, and Make covers no-code scenarios.
Who are n8n's main competitors?
In no-code workflow automation, n8n's main competitors are Zapier and Make (proprietary SaaS) plus Windmill and Activepieces (open-source). For autonomous AI agents — where n8n is weakest — its competitors are purpose-built agent runtimes: HostAgentes Paperclip (multi-agent orchestration, from $15/mo) and OpenClaw (BYOK agents, from $3.99/mo), with Langflow as the open-source visual prototyping option.
Is there a free open-source alternative to n8n?
Yes. Activepieces is the closest true open-source n8n alternative — a visual builder with a similar mental model and a genuinely open-source license. Windmill is the code-first option (real Python/TypeScript/Go with a UI on top), Node-RED is the lightweight veteran for event-driven flows, and Kestra covers declarative YAML pipelines. All are free to self-host; you pay only for your own server. One nuance: n8n itself is fair-code rather than OSI-approved open source — self-hosting is free and the source is public, but the license restricts offering n8n itself as a service. And if your goal is autonomous AI agents rather than workflow automation, no open-source workflow engine closes the gap — you need a purpose-built agent runtime like Paperclip or OpenClaw.
What's the best open-source n8n alternative for AI agents?
Depends what 'for AI agents' means. If you want an open-source editor with AI-native workflow features, Sim is the 2026 entrant drawing the community buzz — its maintainers pitch native agent memory, multi-model orchestration, and MCP support, self-hostable via Docker Compose or Kubernetes. If you want the closest like-for-like open-source swap for n8n's classic automation UX, that's Activepieces (with Windmill for code-first teams) — and HostAgentes runs managed hosting for Activepieces, Langflow, and Flowise if you want open-source tools without server ops. But if 'for AI agents' means agents that reason, decide, and remember across runs, no open-source workflow builder closes that gap — that's an agent runtime (Paperclip, OpenClaw), a different paradigm from any editor.
What is better than n8n for AI agents?
For AI agents, HostAgentes Paperclip and OpenClaw are better fits than n8n because they provide the three things n8n's workflow model lacks: persistent agent memory across runs, native reasoning loops (n8n's DAG forbids cycles), and per-agent token budgets. n8n remains a strong choice when every step of the automation is known in advance — the two are often used together, with n8n handling triggers and Paperclip handling reasoning.
Is n8n self-hosting actually free in 2026?
The Community Edition is free, but n8n self-hosted pricing isn't free at the tier companies actually buy: the Business plan costs €667 per month (billed annually) and is self-hosted — you operate the server AND pay n8n, because SSO/SAML, separate environments, and Git version control are gated to that tier. Cloud plans are execution-metered, starting at €20/month billed annually. HostAgentes takes the opposite approach: OpenClaw from $3.99/month and Paperclip from $15/month, with no execution-based billing inside plan limits and no server to operate. (n8n figures from n8n.io/pricing, verified September 2026.)

When the steps aren't known ahead of time, you need an agent runtime.

Paperclip handles multi-agent orchestration with persistent memory and governance. OpenClaw gives you BYOK agents from $3.99/mo. Both run on HostAgentes with zero infrastructure to manage.
