Activepieces

Activepieces is an open-source workflow automation platform that works like Zapier or Make but can be self-hosted, so teams can keep data on their own infrastructure instead of routing it through a third party. It offers a visual, drag-and-drop flow builder with several hundred pre-built integrations (called "pieces") covering common SaaS tools, plus branching, loops, and the ability to write custom JavaScript or Python steps when the no-code blocks aren't enough. More recently it has added AI agent and MCP support, letting flows call LLMs or act as tool servers for AI agents rather than just chaining simple triggers and actions.

It's aimed at developers, IT teams, and technical founders who want automation without vendor lock-in or per-task pricing that scales badly as usage grows. Self-hosting via Docker is a big part of the pitch, along with an Apache-licensed core and a marketplace where anyone can build and publish new pieces, which has let its integration library grow quickly through community contributions rather than a single vendor's roadmap.

What sets it apart from Zapier or Make is mainly the combination of open-source licensing, self-hosting, and code-level extensibility in one tool, since most no-code automation platforms are closed and cloud-only. It's a common choice for companies with compliance or data residency requirements, or ones that simply want to avoid being tied to a single vendor's pricing model as their automation needs grow.
