You hold the helm.

Your crew.
Under your watch.

You launched the agent. Now what?

Looping for an hour. You had no idea.

It opened your auth layer. You never asked.

$180 in token usage. Still not done.

Tmonier shows you — in real time. When something's off, you're the one who catches it.

How it works

Watch. Know. Decide.

One Claude Code agent. Every file read, every edit, every test run.
Loops caught. Scope drift flagged. Nothing ships without your approval.

What Tmonier caught

Not heuristics. Counts, boundaries, and thresholds — the kind of rules that don't hallucinate.

Live

Real-time visibility

Every file read, every edit, every test run — streamed live to your dashboard.

Alert

Loop & drift detection

Stuck in a cycle? Touching files outside scope? Flagged before it burns your budget.

$ Cost

Context & cost awareness

Context window filling up? Wrong model for the job? Tmonier tells you before you waste tokens.

Gate

Checkpoints & rollback

Nothing ships without your signal. Things go sideways? Roll back to the last clean state in one click.

Local

Local-first daemon

Runs on your machine. Your code never leaves localhost. Dashboard connects via local websocket.
