ActivePieces

Activepieces is an open-source, self-hosted application that automates workflows by connecting different applications. It provides a no-code builder for creating automation flows, allowing users to link various services and trigger actions based on specific events. The software is deployed as a server and is designed for both technical developers and non-technical business users who need to synchronize data or automate repetitive tasks across multiple platforms.

Users can build complex flows using a visual interface or extend the platform by creating custom pieces. The system supports a wide range of integrations, including Google Sheets, OpenAI, and Discord, and allows for self-hosting to maintain full control over data and security. This makes it suitable for environments that require network-gapped installations or strict data privacy compliance.

Key features

• Over 200 pre-built integration pieces published as npm packages
• Support for loops, branches, and auto retries within workflows
• Native AI pieces and an AI SDK for building agents
• Ability to write custom code pieces using TypeScript and NPM
• Human-in-the-loop capabilities for execution delays and approvals
• Built-in human input interfaces such as forms and chat interfaces
• Versioning for all created automation flows
• Integration of pieces as MCP servers for use with LLMs

The platform is built on a type-safe framework written in TypeScript, which enables developers to create and test new pieces locally with hot reloading. Because pieces are distributed via npm, the ecosystem is open for community contributions, with a significant portion of the available integrations provided by the community. The architecture is designed for organizational use where developers set up the core infrastructure and non-technical staff manage the automation logic via the builder, allowing for custom branding and administrative control.

Activepieces is an extensible, AI-first automation platform that balances a no-code experience with a developer-centric framework for building and deploying integration tools.
