TraceKit vs Sentry: Full-Stack Observability in One Platform
Sentry pioneered error tracking, and it shows -- years of polish on error grouping, source maps, release management, and session replay. TraceKit now covers all of that for web applications AND adds full distributed tracing, live code monitoring, and browser-to-backend trace correlation in a single platform. Same error tracking power, plus the backend observability Sentry was never built for.
Pricing and feature information is based on publicly available data as of March 2026. Check Sentry's website for the latest.
Why developers choose TraceKit
Live Code Monitoring
Set live breakpoints and capture snapshots in production code. Sentry shows you errors after they happen -- TraceKit lets you debug code as it runs, without waiting for the next crash.
Pricing Simplicity
$29/month flat vs event-based pricing with overages at $0.000290/event. No counting errors, no worrying about quota spikes during a bad deploy.
Full Stack in One Tool
Frontend errors, session replay, source maps, AND backend distributed traces -- all in one platform. Sentry pioneered replay; TraceKit connects it to distributed traces so you can follow a user session from browser click to backend database query.

Pricing Comparison
TraceKit
$29/month
Flat monthly
One price includes distributed tracing, live code monitoring, custom metrics, dashboards, alerts, and security scanning. Unlimited traces.
None. What you see is what you pay.
Sentry
Free (5k errors/month), Team $26/month (50k errors), Business $80/month (100k errors)
Per-event tiered
Sentry prices by error volume. The Team plan includes 50k errors, 100k performance units, and 500 replays per month. Additional errors are $0.000290/event. Performance monitoring and session replay have separate quotas.
Event-based pricing means costs scale with error volume. High-error-rate applications or noisy deployments can burn through quotas quickly. Performance monitoring has its own separate event limits.
Pricing considerations with Sentry
- Event-based pricing means noisy deployments or error spikes can burn through your monthly quota
- Performance monitoring events are counted separately from error events
- Business plan at $80/month still has event limits -- overages add up at $0.000290/event
- Need more than error tracking? You will need additional tools for full APM coverage

// TraceKit: One-line SDK setup

We believe in honesty. Sentry is a great product, and there are situations where it is the better choice.
- You need mobile SDK support (iOS, Android, React Native, Flutter) -- Sentry's mobile ecosystem is mature and battle-tested
- You need years of polish on error grouping, fingerprinting, and issue management workflows
- You want strong open-source roots and a large community ecosystem
Frequently Asked Questions
TraceKit is a full APM platform that now includes browser error tracking, source maps, release tracking, and session replay -- alongside distributed tracing and live code monitoring. For web/JS applications, TraceKit covers everything Sentry offers plus full distributed tracing. For mobile applications (iOS, Android, React Native, Flutter), Sentry remains the stronger choice.
You can, but you may not need to. TraceKit now covers error tracking, source maps, session replay, and release tracking for web applications. The main reason to keep Sentry alongside TraceKit would be for mobile SDK coverage. For web-only stacks, TraceKit handles the full pipeline from browser error to backend trace.
Yes, for web/JavaScript applications. TraceKit now offers browser error tracking, source maps with debug IDs, release tracking with regression detection, and session replay linked to distributed traces. For mobile apps (iOS, Android, React Native, Flutter), Sentry still leads with mature, battle-tested mobile SDKs.
TraceKit is $29/month flat with unlimited traces. Sentry's Team plan is $26/month for 50k errors, and the Business plan is $80/month for 100k errors. If your error volume is low, Sentry can be cheaper. If you need full APM beyond error tracking, TraceKit includes everything at one price.
Sentry has performance monitoring with transaction tracing, but it is not a full distributed tracing solution. TraceKit provides complete distributed trace collection with waterfall and flamegraph visualization, span-level detail, and cross-service correlation. TraceKit also captures browser-side traces that connect to backend spans via W3C traceparent, giving you true end-to-end visibility from click to database query.
It depends on your primary need. If you mostly need to catch and fix errors with great stack traces, Sentry's free tier (5k errors/month) is an excellent starting point. If you need production debugging, distributed tracing, and custom metrics, TraceKit at $29/month covers all of that in one tool.
