N8N

What it does

n8n is the automation tool for teams that keep data in-house: self-host the instance, wire any API, and build agentic workflows with native LLM and vector-store nodes. Code steps run real JavaScript or Python.

The source-available licence allows self-hosting with fair-use boundaries. Cloud plans exist for teams that would rather not run servers.

Standout features

• Self-hostable — data never leaves
• Native AI agent and LLM nodes
• Code steps in JS or Python
• Unlimited executions when self-hosted
