Activepieces

Activepieces provides a self‑hosted, open‑source platform for building no‑code automation workflows similar to Zapier or Tray. Users can connect triggers and actions across more than 200 integrations—such as Slack, Trello, Google Sheets, and OpenAI—through a visual builder that supports loops, branches, retries, and versioned flows. The system is written in TypeScript, allowing developers to create custom “pieces” that are published as npm packages and can be hot‑reloaded locally.

The platform emphasizes an AI‑first approach, offering native AI pieces and an SDK that lets large language models interact with flows via tools like Claude Desktop, Cursor, or Windsurf. Human‑in‑the‑loop features include delayed execution, approval steps, and input interfaces such as chat or form dialogs. Because it runs on the user’s own infrastructure, it remains network‑gapped and secure, with branding and control fully customizable for organizational use.

Activepieces is distributed under the MIT license, offers a free tier without subscription requirements, and is maintained as a stable, community‑driven project with frequent updates and a public Discord for support.
