Catch Fly.io apps stuck in a restart loop
Every hour, WebRun opens the Fly.io dashboard, reads how many times each machine restarted for every app, logs any app crossing your restart threshold to Google Sheets with the count and region, and emails you an alert.

How do I get alerted when a Fly.io app is stuck restarting?
WebRun checks every Fly.io app each hour, reading how many times each machine restarted. When an app crosses the restart threshold you set, it logs the breach to Google Sheets with the count and region, then emails you an alert, so a crash loop gets caught within the hour instead of burning through resources unnoticed.
- Crash loops get caught within the hour they start
- Every breach is logged with the restart count and region
- Your inbox stays quiet on hours nothing crosses the threshold

Questions, answered
Will it restart or roll back an app on its own?
No. WebRun only reads restart counts and reports a breach. Restarting, rolling back, or redeploying an app always stays a manual step in Fly.io.
What counts as a restart loop?
More restarts in an hour than the threshold you set, the pattern that usually means a machine is crashing on startup instead of running normally.
Does it check every app on the account?
Yes. It reviews every app under the account each hour, not just the ones you check manually.
