Free to start
n8n
Free alternative to: Zapier
License: Sustainable Use License (fair-code, source-available — NOT OSI open-source)
Free terms: Self-hosting is free under the Sustainable Use License with no feature gating; n8n Cloud plans are paid.
What it does
Fair-code workflow automation platform with 400+ integrations, visual building plus custom code (JS/Python), and native AI-agent/LangChain capabilities.
Heads-up: Distributed under the Sustainable Use License + n8n Enterprise License — source is fully visible and self-hostable, but it is NOT open-source by the OSI definition. This is the key distinction the directory must state plainly.
