warden / watch something

Point Warden at something you have running.

One URL is enough to begin. Add your deploy hook and Warden can bring the thing back when it goes down; add where to reach you and you hear about it. Tell it the machine and the process as well and it can read the logs, the process table and the last few commits when that URL stops answering — the difference between being told something is down and being told why.

What is itNameWhat breaks for a person when this is down optionalWarden puts this in front of itself while it works. It is the difference between a restart and a careful one.

How Warden can tell it is alrightURL to checkAsked every five minutes. Two failures in a row count as an outage — one blip on a network does not. This Warden watches public addresses only.

Expect statusAnd the body contains optional

Deploy or restart hook optionalA URL that redeploys or restarts this when POSTed — Render, Railway, Vercel and Coolify all issue one. It is the one thing Warden can do for a service it cannot reach. The key in it is never shown again.

Where to reach youA webhook optionalA Slack or Discord incoming webhook, or any URL that takes a POST. You hear when something breaks, and when Warden stops to ask. Change it later in Settings.

What Warden may do when it is not alright

Watch onlyLook at anything — logs, the process table, recent commits — and work out what is wrong. Change nothing, ever. Start here if it is not yours, or you are not ready.Ask me firstInvestigate, work out the fix, and show you the exact command it would run. Then stop and wait. The run is held open until you answer, however long that takes.Fix what undoes itselfRestart it, start it, run the tests — unattended, then re-run the failing check to prove it worked. Anything that does not undo itself still comes to you.

Four actions — migrating a database, deleting data, rotating a secret, destroying infrastructure — are refused by name whatever you pick here, and no rule can turn them on. You can change everything else, action by action, on the next screen.
