Open source automation platform replacing Zapier with TypeScript
AI-powered automation platform with 280+ integrations, type-safe TypeScript framework, and MCP server support. Self-hosted alternative to Zapier for technical and non-technical teams.
Activepieces is an extensible automation platform built for teams that need full control over their workflows. With an intuitive no-code builder and a type-safe TypeScript framework, it bridges the gap between business users and developers.
The platform features 280+ integrations ("pieces") published as npm packages, with 60% contributed by the community. Every piece doubles as an MCP server compatible with Claude Desktop, Cursor, and Windsurf. Developers benefit from hot reloading, full customization, and the ability to create pieces in TypeScript, while non-technical users enjoy an intuitive builder with AI copilot assistance.
Activepieces supports advanced workflow features including loops, branches, auto-retries, versioning, and human-in-the-loop approvals. Native AI pieces enable experimentation across providers, with an AI SDK for building custom agents. Self-hosted deployment ensures network-gapped security, while white-labeling and granular controls make it suitable for organizations requiring brand consistency and data sovereignty. The platform includes human input interfaces like chat and form triggers, plus ASK AI functionality that lets non-technical users manipulate data without coding.
When teams consider Activepieces, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
AI-Assisted Data Processing
Non-technical staff clean and transform data using ASK AI in code pieces without writing code, reducing dependency on developers.
Approval-Based Workflows
Finance teams automate expense processing with human-in-the-loop approval gates, ensuring compliance while reducing manual routing.
Custom Client Portals
Agencies white-label the platform and build client-specific automations with branded interfaces and custom integrations.
LLM-Powered Integrations
Developers expose Activepieces integrations as MCP servers to Claude Desktop, enabling AI assistants to trigger workflows directly.
Activepieces is a self-hosted alternative offering full source code access, TypeScript-based custom integrations, and no per-task pricing. It trades Zapier's managed service convenience for complete control and customization.
MCP (Model Context Protocol) servers let LLMs like Claude interact with external tools. All 280+ Activepieces integrations work as MCP servers, enabling AI assistants to trigger workflows directly from Claude Desktop, Cursor, or Windsurf.
No for building workflows—the no-code builder is designed for non-technical users. TypeScript is only required if you want to create custom integrations or modify existing pieces.
The platform is designed for self-hosted deployment to ensure data sovereignty and security. Check the official documentation for deployment options and requirements.
Integrations (pieces) are TypeScript npm packages. Follow the Contributor's Guide in the documentation to build, test with hot reloading locally, and submit your piece—it will be published to npmjs.com and available to all users.
