TrackJS review
Detailed browser telemetry for JavaScript teams, with paid plans and short retention windows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TrackJS is a cloud error monitoring product for production JavaScript applications. It focuses on browser-side failures, including JavaScript errors, unhandled promise rejections, network failures, and console errors, while also supporting Node.js integrations. JavaScript-focused teams can use it to investigate client-side problems with stack traces, telemetry timelines, filtering, searching, alerts, release context, and source maps.
Pricing is based on page-view traffic rather than error volume. Starter costs $49 per month with monthly billing and includes 100,000 monthly page views, one application, 10 days of data retention, 800,000+ errors per month, and unlimited users. Professional costs $99 per month and raises those limits to 1 million monthly page views, five applications, 15 days of retention, and 2,700,000+ errors per month. Business costs $199 per month, includes 10 applications, 30 days of retention, monthly page views selected by account, and 3,800,000+ errors per month. Annual billing shows Starter at $45 per month. Enterprise uses customized contracts and service levels.
The standout area is browser telemetry depth: TrackJS connects user actions, navigation, console logs, and network requests in a timeline around an error. Application and release version context, source-map processing, real-time alerts, email reports, unlimited server-side ignore rules, and the AI Code Debugger add investigation and triage options. Integrations include React, Angular, Next.js, Express, and Node.js. Choose TrackJS if detailed frontend JavaScript capture is more important than broad observability coverage. Teams that need session replay, a free plan, or longer retention at the entry tier should consider alternatives.
