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

CatchJS automatically collects all uncaught exceptions from your users' browsers, and presents a detailed log of their circumstances. This includes the browser type, the stack trace, and even screenshots and the click trail which lead to the error.

Add the above snippet to your site's HTML, create an account, and you are ready to begin tracking JavaScript errors.
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.
