Sentry groups exceptions by root cause, attaches the stack trace, the affected release, and the breadcrumbs leading up to the failure, which turns 'a user says it is broken' into a specific line of code. Release tracking and the link back to the commit are what make it worth the instrumentation effort.
Who it is for
A small engineering team that needs to know which deploy introduced an error before users report it.
Key features
- Groups errors by root cause and stack trace
- Release tracking ties errors to commits
- Breadcrumbs show events before a crash
- Performance tracing and span analysis
- Alerts to Slack, PagerDuty, and email
- Self-hosted option for regulated teams
Where it falls short
The event quota is easy to blow through during an incident - exactly when you need the data - and an untuned project generates so much noise that the team stops reading it.
Pricing
Free developer tier includes a monthly error quota with 30-day retention; paid plans are per organization, and longer retention plus SSO are the gates.
Prices move; the tier structure is the part that stays true. Check current pricing on Sentry.
