Activepieces is an open-source automation platform positioned as an extensible alternative to Zapier, with a visual builder for connecting applications, data, and AI workflows. Its integration system is built around type-safe TypeScript packages called pieces, allowing both the core team and community to add new services and actions.

The platform combines no-code workflow construction with AI-native capabilities, human-in-the-loop steps, forms and chat interfaces, self-hosting, and enterprise controls. Activepieces also exposes its integration pieces as MCP tools, making the same application connectors usable from LLM clients and coding assistants.

Activepieces is a strong fit for teams that want business automation without giving up the ability to inspect, extend, or self-host the underlying system. Developers can build custom pieces while non-technical users assemble workflows visually, which makes it useful for organizations that need both flexibility and accessible automation.
