Automated Expo EAS Build Failure Alerts
Every hour, WebRun opens Expo, checks EAS Build for any build that failed, texts the mobile lead through WhatsApp naming the platform and the failing step, and books a calendar reminder to retry the build before the release freeze so a broken build doesn't quietly slip past the deadline.
How do I catch failed Expo EAS builds before a release deadline?
WebRun checks Expo EAS Build every hour for a failed build, texting the mobile lead through WhatsApp with the platform and failing step. It also books a calendar reminder to retry before the release freeze, so a broken build gets fixed with time to spare instead of surfacing right before the deadline.
- Failed builds reach the mobile lead within the hour
- Retries get booked before the release freeze, not after
- Broken builds surface with time to fix them, not at the deadline
Built for mobile engineering teams · React Native developers · release managers · platform teams

Questions, answered
Will it retry the build itself?
No. WebRun only reports the failure and books a reminder. Retrying the build is always started by your developer.
Does it submit anything to the App Store or Play Store?
No. It only checks EAS Build status. Submitting a build to a store is always a separate, deliberate step your team takes.
How fast does a failure get reported?
Within the hour it happens, since every build profile is checked each hour.
