What TrackJS is

TrackJS is a cloud service that monitors frontend JavaScript errors across real users. Its agent captures unhandled errors, rejected promises, failed network calls, and console errors. The Telemetry Timeline shows preceding network requests, interactions, console logs, and navigation events. An optional AI Debugger examines telemetry, browser data, and source code to explain failures and suggest fixes. The agent is 8 kilobytes, has no dependencies, and sends data asynchronously. TrackJS says it uses no end-user cookies, identifiable profiles, or session recordings, and does not record user input or network payloads. Integrations include Angular, Axios, NextJS, React, Redux, Vue, and Web Workers. Plans start at $45 a month billed yearly, with a free trial but no free plan. Starter includes 10 days’ retention; higher plans provide longer periods.
