Activepieces

Activepieces is an open source automation platform for building AI workflows and no-code flows. It is designed as a Zapier replacement for teams that want extensible automation, a type-safe pieces framework, and self-hosted control over the system.

It uses TypeScript pieces, with loops, branches, auto retries, HTTP, NPM code steps, and versioned flows. Contributed pieces become MCP servers for use with Claude Desktop, Cursor, or Windsurf, and the builder includes human-in-the-loop delays, approval steps, and chat or form input interfaces.

The Community Edition is released under the MIT license, with enterprise features under a commercial license. Pieces are open source npm packages published to npmjs.com as they are contributed, and the self-hosted platform can run network-gapped for control over your data.
