Overview
n8n is a workflow automation tool that lets you connect apps and services through a visual node-based editor or custom code. It ships with 400+ integrations, native AI/LangChain nodes for building agents, and supports self-hosting via Docker. It is the most popular open Zapier/Make alternative and pairs no-code building with the ability to drop into JavaScript when needed.
Key features
- Visual node-based editor for chaining triggers, actions, and conditional logic
- 400+ prebuilt integrations for apps, APIs, and databases
- Native AI/LangChain nodes for building agent and RAG workflows
- Inline JavaScript (and Python via nodes) for custom transforms when no-code hits its limits
- Self-hosting via Docker, Docker Compose, or Kubernetes; managed cloud also offered
- Webhook triggers, scheduling, and HTTP request node for arbitrary API calls
Our take
n8n hits a genuinely useful middle ground: you can drag-and-drop a workflow together like Zapier, but when the visual nodes don't cover your case you drop into a JavaScript code node instead of hitting a wall. The 400+ integrations plus native AI/LangChain nodes make it the most capable open automation tool around, and a basic Docker deployment is straightforward to stand up. The big caveat is licensing: n8n is fair-code under the Sustainable Use License, not true open source, so commercial use and reselling are restricted in ways you should read before building a business on it. Operationally, expect to manage your own database, queue mode, and credential encryption as workflows scale, and complex flows can become hard to debug. For a self-hoster who wants real automation power without a full SaaS subscription, the trade-offs are usually worth it.
Ideal for: Technical teams who want a self-hosted Zapier/Make alternative and are comfortable dropping into code when a workflow gets complex.
Where it falls short of Zapier
- Source-available (Sustainable Use License), not true OSI open source; some enterprise features (SSO, log streaming, external secrets) are gated behind paid tiers.
- Self-hosted instances require you to manage your own queue/Redis and Postgres for scaling and reliability.
- Far fewer pre-built app connectors than Zapier's 6,000+ catalog.
- Concurrency and execution throughput on the free self-hosted tier require manual queue-mode tuning.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
