Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.

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.
