The public fleet

Three real services, no sign-up.

Watch something of yours

This is the fleet this Warden actually watches, live. It is not a screenshot, the outages in it really happened, and the button below really causes one.

Nothing of yours yet.

Give Warden a URL and it starts checking. Add your deploy hook and, when that URL stops answering, it works out why over the network, redeploys within the rules you set, and proves it by asking the check again. Give it the machine and the process as well and it can read the logs, the process table and the last few commits too.

No account and no email: a signed cookie makes a service yours. Below is the fleet this Warden actually watches, live — it is not a screenshot, and the outages in it really happened.

SAGE

Someone else's production, and it is submitted to two competitions. Warden watches it and touches nothing.
