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.

Test, monitor and improve the voice AI agents you already run
Run your agent against hundreds of realistic personas, accents, background noise and edge cases before a customer ever dials in.
Red-team callers attempt prompt injection, jailbreaks and social engineering to check your agent holds policy under pressure.
Every live call is scored as it lands on more than 500 metrics, with issues filed, alerts fired and traces attached.
Purpose-built audio models measure pronunciation, emotion, vocal stress, pace, interruptions and dead air, not just transcript quality.
