CompozyOS

The autonomous control plane for your AI coding agents

One board for every agent session

Sessions are grouped into Needs you, Working, Waiting, In review, and Done so you immediately see which agent is blocked on your decision.

Always-on check-ins

Agents review their project on a schedule in hidden read-only sessions, stay quiet when nothing changed, and report back in a single card.

Loops with honest endings

A Loop pairs a goal with a way to verify it and a stop; runs are iteration-capped and end as done, no-op, blocked, failed, exhausted, stalled, or canceled.

Schedules, triggers, and webhooks

Put agent work on a cron-like schedule, a runtime trigger, or a signed webhook, with every run recorded automatically.

Strengths & Pros

+Runs the agent CLIs you already use rather than locking you into one vendor
+Local-first and MIT-licensed, with your subscriptions and API keys staying yours
+Always-on agents and Loops make unattended, verifiable work practical
+Same jobs managed from the web UI, the CLI, or HTTP
