Sentry
Tells you your app broke, for whom, and on which line — before users email you.
1. Learn it
- It captures errors in production with a stack trace and the steps that led there.
- Without it, a production bug is invisible until someone complains.
- Group similar errors, fix the loudest, ignore the noise.
Cost: Free tier.
2. Practice it
Simulated — nothing real happensTrace the 500
Production returns 500 on checkout only. List the first three things you look at.
3. Connect it
Real — your own account- 1Create a Sentry project, add the SDK, trigger one test error.
MessyDev never signs you up, spends your money, or touches your accounts. You do that part.
4. Use it
Before launch. Finding out from a customer is worse.
Honest alternatives
There is no single correct stack. Any of these would be a reasonable choice instead.
