Sentry
Error monitoring. The stack trace from production, with the release.
Best for Knowing what broke in production
Sentry is an error-monitoring platform. The SDK reports exceptions from your app, groups them, and ties them to a release. Use it the day the app has a real user. There is a free developer plan. Event quotas and team pricing: check site.
Best use cases
- Frontend and backend exception tracking
- Seeing which deploy introduced a crash
- A first observability tool before a full platform
Pros
- + The SDK drop-in is a known afternoon of work
- + Stack traces are grouped instead of living in a log hose
- + A free tier exists for small apps
Cons
- − It tells you about failures. It does not prevent them
- − Quota pricing: check site
Pricing
Free developer plan and paid event quotas. Current prices: check site.
