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, human-in-the-loop workflow layer for on-premise AI
AI reads, extracts and drafts inside a workflow, but a named person reviews and approves each critical step so there is an audit trail by design.
Build processes with triggers, conditions, forms, tasks and approvals without writing code, and refine them as the process evolves.
Ready-made workflows for HR, sales, finance, procurement, IT, healthcare and more, usable as-is or as a starting point.
Apache 2.0 core with public code, so security teams can audit it and organisations can deploy on-premise or in a private cloud.
