Activepieces is a workflow automation platform that positions itself as an open-source replacement for Zapier. A no-code builder lets non-technical team members connect apps and automate tasks, while developers extend it with "pieces", integrations written in TypeScript and published as npm packages.

What stands out

• Large, open piece library: hundreds of integrations, with the project stating that most of them were contributed by the community.
• Ready for AI tools: pieces are automatically exposed as MCP servers, so assistants such as Claude Desktop, Cursor or Windsurf can use them.
• AI-first building blocks: native AI pieces and an SDK let you add agents to flows.
• Self-hosted option: run it on your own infrastructure, including environments without outside network access.

Who it suits

Teams that want Zapier-style automation without per-task pricing, and developers who prefer writing custom integrations in a typed language with hot reloading.
