Track errors when they happen. You are notified when something goes wrong.
Fixing bugs gets a lot easier when you know how they happened
Be safe knowing that no hidden bugs are silently ruining your users' experience
Create a flawless user experience. Capture any error caught on your site and see it immediately in the error log. You are notified when a new error occurs.
Playback the clicks that lead to the error, with a screenshot straight from the users' device.
Avoid guesswork and see exactly how the error happened.
Just add the following script tag, set up an account, and your JavaScript error tracking is ready.
<script src="https://cdn.catchjs.com/catch.js"></script>
The CatchJS script will set up JavaScript error monitoring directly from your users' browsers. It will automatically collect uncaught exceptions and present a detailed log of their circumstances. Read more about setting up CatchJS.
CatchJS has processed billions of errors for customers around the world.
Create delightfully fast websites. Don't let error tracking slow things down. The CatchJS library is up to 8 times smaller than our competitors, only 1.77KB gzipped.
Get the full error context and see exactly what went wrong. Source maps will be collected and applied automatically, with no action needed from you.
We track JavaScript exceptions, not users. Services that perform user tracking will store personal data, and thus require collecting explicit consent from the user, according to EU law. CatchJS is privacy preserving by default and does not require the extra work of collecting such consents.
Track and log whatever data you'd like, using the catchjs.log() function. It is like the developer console, but logging remotely from your users' device. In addition to JavaScript error reporting, you get a dead simple way to monitor any event of interest.
Get alerts when new errors happen, along with weekly summaries.
