Agents that ship real code.

Describe what to build and let the agent work autonomously until it's done.

  • File ops, search, shell, and task delegation built in
  • Explorer and executor subagents for parallel work
  • Multi-model support with AI Gateway

Durable workflows that survive anything.

Agent loops run as durable workflows that survive restarts, retry on failure, and coordinate multi-step operations over time. No work is ever lost mid-run.

  • Resumable agent loops with automatic checkpointing
  • Post-finish: usage tracking and session telemetry
  • Reconnect to running workflows from any client
