TrackJS

Frontend-only JavaScript error tracking with telemetry timeline.

By TrackJS, LLC · Founded 2014 · Minneapolis, MN · private

TrackJS is the focused frontend-only JavaScript error tracking platform. Founded 2014 by Todd Gardner. The product specifically refused to expand into backend tracking, performance monitoring, or session replay, and that focus is the value proposition. The SDK is among the lightest in the category, the telemetry timeline (network calls, console logs, user actions) before the error is the strongest in the frontend space, and pricing is flat-rate with no per-event surprise. The trade-off: only frontend JavaScript. If your stack is server-side, TrackJS is not for you. The advantage: for marketing sites, frontend-heavy single-page apps, and JavaScript-only teams, TrackJS often catches things Sentry misses (browser-specific quirks, third-party script failures, network-level errors).

    Founder publicly affirmed frontend-only focus
    Founder restated TrackJS will remain frontend-only and not expand into backend or full APM
Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.
