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.

AI voice agents that run your customer calls end to end
telli Studio lets teams create and refine agents by describing the conversation in natural language, without engineering work.
Deploy agents with native fluency, local accents and cultural context across 30+ languages, with curated voices and optional voice cloning.
Pre-built and custom actions let agents act during a call, while post-call workflows push outcomes into connected systems automatically.
Native Salesforce and HubSpot connections plus API access, with telli phone numbers or bring-your-own via SIP trunking.
