TrackJS — Developer Tools

What is TrackJS?

TrackJS is a frontend error monitoring tool that helps developers track, diagnose, and fix JavaScript errors in production. It captures errors across browsers and frameworks, providing a chronological timeline of network requests, user interactions, console logs, and navigation events leading up to each error.

What problem does it solve?

Debugging production JavaScript—especially code generated by AI—is often time-consuming because errors lack context. TrackJS gives developers the full story behind every error, making it easier to identify root causes and fix issues before they escalate into incidents.

Who is it for?

TrackJS is designed for developers and teams shipping frontend code, from small businesses to large enterprises. It is particularly useful for teams using AI coding assistants that generate code quickly but struggle to debug the resulting runtime issues. It is not for backend-only monitoring or infrastructure-level observability.

Real use cases

Use TrackJS to monitor error rates across user segments, filter out third-party noise, and receive AI-generated debugging insights that explain what went wrong and how to fix it. Integrate it with React, Angular, Node.js, Next.js, or any browser environment.

• Error Monitoring — Track JavaScript errors in real time, with full stack traces and browser context.
• Timeline of Events — See network requests, console logs, and user interactions before each error.
• AI Code Debugger — Get actionable explanations and fixes for cryptic errors, including framework-specific quirks.
• Discoverable Error Filters — Use one-click filters to zero in on patterns across users, browsers, and pages—no query language needed.
• Unlimited Ignore Rules — Automatically filter out third-party errors and expected issues to focus on what matters.
• Framework Compatibility — Works with any browser and framework, including React, Angular, Node.js, and Next.js.
