Tool Breakdown
Sentry
Open-source, broadest platform coverage, AI-assisted root cause analysis, and the largest developer community make Sentry the best default error tracking tool for most teams.
- Open-source — self-host or use the cloud product
- Covers every platform: web, mobile (React Native, iOS, Android), backend
- Sentry AI identifies probable root causes and suggests code fixes
- Free tier caps at 5K errors/month for cloud product
- Initial configuration for release tracking and alerting requires investment
Rollbar
Real-time error monitoring with RQL query language, intelligent error grouping, and deployment tracking.
- RQL (Rollbar Query Language) enables SQL-like queries over error data
- Intelligent grouping reduces noise by clustering related errors
- Deployment tracking links every error to the release that introduced it
- Less broad SDK coverage than Sentry — fewer mobile options
- Essentials and Advanced tiers require sales contact for pricing
Bugsnag
Mobile-specialized error monitoring with App Stability Score, release health tracking, and native iOS/Android crash analysis.
- App Stability Score — single % metric for mobile app health per release
- Best native iOS and Android crash grouping in the market
- Release health dashboard shows crash-free session rate per version
- Web and backend coverage is weaker than Sentry
- Custom pricing on paid tiers — no transparent public pricing
Frequently Asked Questions
Which error tracking tool is best for a startup? +
Sentry is the best choice for most startups. Its free tier (5K errors/month) is sufficient for early-stage products, the open-source version is available for self-hosting if the cloud free tier isn't enough, and the SDK covers every stack a startup might use. The Sentry Team plan at $26/mo is also the most transparent pricing in this comparison.
Do these error tracking tools support source maps for JavaScript? +
Yes — Sentry, Rollbar, and Bugsnag all support source map upload for JavaScript. Source maps de-obfuscate minified production stack traces so errors show the original source file and line number. Sentry has the most mature source map tooling, including automatic upload via Sentry CLI and Webpack/Vite plugins.
Can error tracking tools send alerts to Slack or PagerDuty? +
Yes. All three tools — Sentry, Rollbar, and Bugsnag — integrate with Slack, PagerDuty, and OpsGenie for error alerting. You can configure alert rules based on error rate thresholds, new error types, or regression of previously resolved errors. Sentry has the most granular alerting rules of the three.
