TrackJS

Overview

TrackJS is a JavaScript error monitoring tool that helps developers track, log, and recreate bugs in production web applications. It captures telemetry data including console logs, network activity, and visitor interactions leading up to an error, providing the necessary context to resolve issues quickly. Designed for simplicity, it works across all major web frameworks and provides detailed insights into end-user experiences.

What it does

• Monitors web applications to catch and report JavaScript errors.
• Provides detailed telemetry and network logs leading up to crashes.
• Helps developers recreate bugs accurately in their local environments.
• Reduces the time spent debugging obscure frontend issues.

Who it's for

• Frontend Developers
• QA Teams
• IT Administrators
• Small to Mid-Market Businesses

Why it works

• Provides a comprehensive Telemetry Timeline leading up to errors
• Includes enhanced stack traces with source map integration
• Captures end-user context including console logs and network events
• Offers highly customizable reporting and alerting settings
• Simple and fast integration into existing web applications

Founder story

TrackJS was bootstrapped in 2012 by independent engineering consultants Todd Gardner and Eric Brandes. Frustrated by the lack of effective debugging tools for JavaScript applications, they leveraged their own savings to build a solution that provides the context—the 'Telemetry Timeline'—needed to understand how and why code fails in production, while maintaining full ownership of the company.

Alternatives

• Sentry
• Bugsnag
• LogRocket
• Rollbar

Comparison overview

• TrackJS differentiates itself by focusing specifically on simplicity and the Telemetry Timeline, which provides a sequence of events leading to an error.
• Unlike heavier APM tools, it is highly specialized for client-side JavaScript error reporting and lacks the complex overhead of full-stack performance monitoring suites.
