Parallel scheduling, faster iteration

Agents run in sandboxes, coordinated by the PM — iteration gets another gear.

Capabilities

  • Visual orchestration Canvas FSM with live states; parallel requirement lanes and a Gates Inbox.
  • Real Docker sandboxes Execute in containers via ACP and sandbox-gateway; the Web UI uses the API.
  • Multi-agent backends Cursor, Claude Code, CodeBuddy, Trae — pick acpBackend per agent.
  • Artifact contract + MCP write_artifact / set_* / node_complete — isolated by run token.
  • Git credentials in sandbox GITHUB_* / GITLAB_* / SSH; GitLab auto-MR and GitHub gh supported.
  • Single-repo self-host sandbox-gateway and sandbox image sources live in this repo — one clone to self-host.
