TrackJS
JavaScript-only error tracking for browsers and Node.js, priced by page views with unlimited users and no free plan.
In short
- The Starter plan costs $49 a month, or $45 a month billed yearly, for 100,000 page views and 1 application1.
- Starter keeps up to 800,000+ errors a month, at most 20 a minute, with 10 days of history1.
- Every plan has unlimited users; SAML SSO is on the Business plan only1.
- The agents cover browsers and Node.js; no mobile library is listed2,3.
- There is no free plan, only a free trial1.
TrackJS suits teams that only need JavaScript errors from the browser or Node.js, with a timeline of what the visitor did before an error2,7. Pricing follows page views, not errors, and users are unlimited1. The catch: no free plan, 10 days of history on Starter, no mobile or other-language libraries, and alerts reach only email, Slack and Microsoft Teams1,3,5.
Best for: Front-end teams that only need JavaScript error tracking.
