Open-source AI automation that unifies agents, flows and 770+ app integrations
Describe a task in everyday words and the agent determines the steps, chooses tools from your connected apps and MCP servers, and pauses for approval on sensitive actions.
Build automations on a canvas with branching, retries, waitpoints, subflows and error handling, then write inline TypeScript for the steps that need real code.
Every piece is MIT-licensed and community-built, covering the apps you already run, with an HTTP piece for any REST or GraphQL endpoint with auth and pagination handled.
Draft flows by chatting, store structured data in Tables that flows and agents can read and write, and keep internal documents searchable by every agent.

Open-source, block-based platform for building and monetizing your own private AI app suite
Core AI capabilities are decomposed into modules with a plugin layer for custom functionality, so you compose systems by assembling components such as knowledge base, agent or workflow rather than coding from zero.
Build agents on a drag-and-drop canvas, attach knowledge bases, import/export agents via DSL, and interoperate with Coze, Dify and MCP-based tools.
Create structured, extensible knowledge stores, import multiple document formats, and share editing/management rights with collaborators through role-based permissions.
Connect mainstream global large language models and AIGC image models, or run fully local inference through Ollama, with unified key management.
