help TrackJS FAQ

Does TrackJS measure Core Web Vitals or mainly JavaScript errors?

TrackJS is primarily a client-side JavaScript error-monitoring service, not a synthetic page-speed tester. It captures browser errors, stack traces, network context, and user actions rather than continuously measuring global Lighthouse metrics.

Will TrackJS work with React, Vue, or Angular applications?

Yes. Its browser agent is framework-agnostic, so it can monitor applications built with React, Vue, Angular, or plain JavaScript.

How is TrackJS different from Sentry?

TrackJS concentrates on browser-side JavaScript failures and provides tools such as Timeline context and unlimited ignore rules. Sentry covers a broader range of platforms, including backend services and native applications, so teams needing full-stack tracing may find its scope wider.
