What is TrackJS?

TrackJS is a frontend focused JavaScript error monitoring tool that automatically captures unhandled errors, rejected promises, failing network calls, and console errors from web applications. Its Telemetry Timeline reconstructs the network requests, user interactions, and console logs that happened before an error, giving developers the context needed to reproduce and fix issues without guesswork. An AI Debugger analyzes this telemetry alongside source code to explain what went wrong.

TrackJS pricing scales with monthly page views rather than error counts, starting at $49 a month for the Starter plan covering 100,000 page views and rising to $199 a month for the Business plan covering up to 100 million page views. All plans include unlimited users and unlimited server side ignore rules, and discounted pricing is available for bootstrapped and charity organizations.
