Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

Open-source AI workspace for building and governing agents
Create agents on a drag-and-drop workflow canvas, by describing them in chat, or through code and a CLI.
Connect tools like Slack, GitHub, Notion, Salesforce, and Stripe, and pick from every major model provider.
Ground agents in synced sources and manage structured Tables, Files, and artifacts in one workspace.
Enforce permission groups, spend limits, audit records, data retention, and SSO/SCIM from a central console.
