ActivePieces

Activepieces is an open source replacement for Zapier, an automation tool whose defining choice is that its integrations, called pieces, are type-safe TypeScript packages published to npm rather than closed connectors. Roughly sixty percent of them come from the community, and all of the integration source code sits in the same repository.

Contributing a piece has a second effect, because every piece is automatically available as an MCP server for use with LLM clients such as Claude Desktop, Cursor and Windsurf. More than 280 pieces exist on that basis, and local piece development supports hot reloading on your own machine.

The flow builder targets developers and the colleagues who use what they build.

• Control flow: Loops, branches and automatic retries inside fully versioned flows.
• Code steps: Run code with npm packages, or ask AI to write a data cleaning step for a non-technical user.
• Human in the loop: Delay execution or require approval, both built as ordinary pieces on the framework.
• Input interfaces: Chat and form triggers collect information from people directly.
• Native AI: AI pieces let you swap providers or assemble agents with the AI SDK inside the builder.

The Community Edition is MIT licensed while enterprise features carry a separate commercial license. Self-hosting is the intended posture, network-gapped where needed, so developers configure the tools and anyone in the organization builds on the no-code canvas.
