Activepieces

// Overview

Activepieces is an open-source workflow automation tool and a self-hostable alternative to Zapier. You build automations visually in a no-code flow builder, connecting triggers and actions across services like Google Sheets, OpenAI, Discord, and 280+ other integrations.

Each integration is a "piece" — an npm package written in TypeScript. Developers can extend the platform by writing their own pieces with full type safety and hot reloading for local development, while non-technical teammates use the resulting building blocks in the visual builder.

It fits the low-code / no-code corner of workflow automation: developers set up tools and pieces, and the rest of the organization assembles flows without writing code. Because it's self-hosted, your data stays inside your own network, and every piece is also exposed as an MCP server for use with LLM clients like Claude Desktop, Cursor, or Windsurf.

// What it does

• 280+ open-source integrations ("pieces"), with around 60% contributed by the community
• Pieces are TypeScript npm packages with type safety and hot reloading for local development
• Visual no-code builder with loops, branches, auto retries, HTTP, and versioned flows
• Native AI pieces and an AI SDK for building agents directly inside flows
• Every piece is available as an MCP server for use with Claude Desktop, Cursor, or Windsurf
• Self-hosted and network-gapped, so your data stays under your own control

// Getting started

The fastest way to try Activepieces is to run it locally with Docker. This single-container setup uses an embedded database and in-memory queue, so it is meant for personal use or testing rather than production.

docker run -d -p 8080:80 -v ~/.activepieces:/root/.activepieces -e AP_REDIS_TYPE=MEMORY -e AP_DB_TYPE=PGLITE -e AP_FRONTEND_URL="http://localhost:8080" activepieces/activepieces:latest

Commands and code are distilled from the project's own documentation — always check the official repo for the latest.

// When to use it

• Replace Zapier with a self-hosted automation tool so sensitive data never leaves your network
• Let non-technical teammates assemble no-code flows from pieces that developers set up
• Build and ship custom integrations as TypeScript pieces for internal services
• Expose your automations as MCP servers and drive them from LLM clients like Claude Desktop or Cursor
