Tool Breakdown
Sentry
Open-source, broader platform coverage (frontend, backend, mobile), and stronger AI-assisted debugging make Sentry the best default error tracking tool for most development teams.
- Open-source — self-hostable on your own infrastructure
- Covers frontend (JS/React), backend (Python, Go, Java, etc.), and mobile
- Sentry AI suggests probable root causes and fixes from stack traces
- Free tier limited to 5K errors/month — can fill up fast
- Alerting and release tracking configuration requires initial setup time
Rollbar
Real-time error tracking with intelligent error grouping, RQL (Rollbar Query Language) for log analysis, and CI/CD deployment tracking.
- RQL (Rollbar Query Language) for flexible log and error querying
- Intelligent grouping clusters related errors without duplicates
- Deployment tracking shows exactly which release introduced an error
- Less broad platform coverage than Sentry (fewer mobile SDK options)
- Pricing on Essentials/Advanced plans requires contact for current rates
Frequently Asked Questions
Is Sentry really open-source? +
Yes. Sentry's core is MIT-licensed and the full self-hosted version is available on GitHub. Many features of the cloud product are in the community-maintained open-source version. However, some enterprise features (SSO, SCIM, advanced analytics) are cloud-only. The open-source version is a genuine alternative to the cloud product for self-hosted teams.
What is Rollbar's RQL and why is it useful? +
RQL (Rollbar Query Language) is a SQL-like query language for searching and filtering errors and log data. Unlike Sentry's filter UI, RQL lets you write custom queries like 'SELECT count(*) FROM item WHERE level = error AND custom.user_plan = enterprise' — useful for teams with complex multi-tenant applications where errors need to be sliced by customer attributes.
Which error tracking tool is better for frontend React applications? +
Sentry is the stronger choice for React — it has native React SDK with component stack traces, session replay integration, and performance monitoring for Core Web Vitals. Rollbar supports JavaScript including React but without the same depth of React-specific instrumentation that Sentry provides.
