Activepieces

Activepieces is a newer entrant in self-hosted automation: a clean no-code flow builder with connectors ("pieces") for common SaaS tools, designed to be approachable for non-developers in a way n8n sometimes is not.

Being younger, its connector library and community are smaller than the established players, and some enterprise features sit in a paid tier. The core is MIT-ish open source with a piece framework that makes writing your own connectors in TypeScript straightforward.

A good fit for teams who want colleagues, not just engineers, building the automations.
