TrackJS

TrackJS helps development teams catch JavaScript bugs before users ever notice them. Our intelligent error monitoring goes beyond simple crash reports to deliver the complete story behind every issue. What makes TrackJS different: Our innovative Telemetry Timeline captures the full context of each error - network requests, user interactions, console logs, and navigation events that happened before the crash. This means you can quickly reproduce and resolve issues without the performance overhead of session replay tools. Key features include instant error filtering with no query language required, unlimited ignore rules to cut through third-party noise, seamless integration with all modern frameworks like React, Angular, Node.js, and Next.js, a lightweight 8kb agent that won't slow down your site, and privacy-first design with no sensitive user data collected. Trusted by leading companies across software, retail, media, travel, and finance, our customers report saving thousands of developer hours and reducing bugs by up to 80%. Built for the long haul: Bootstrapped and independent since day one, we're aligned with your success, not your problems. That's why we price based on traffic growth, not error volume. From a simple script tag to advanced enterprise integrations, TrackJS installs in minutes and puts actionable error insights at your fingertips.
