Activepieces is an MIT-licensed open-source workflow automation platform built in TypeScript, launched in 2022. It positions itself as the developer-friendly alternative to Zapier, Make, and n8n with 500+ native integrations.

Activepieces enables both technical and non-technical users to create automated workflows through a visual builder while allowing developers to extend functionality via reusable, versioned pieces. The platform supports webhook triggers, scheduled flows, branch logic, loops, and AI-powered actions for content generation and data summarization. It can be self-hosted or used via cloud deployment, eliminating per-task pricing through self-hosting while providing a no-code interface comparable to established platforms.
