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.

Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
