JavaScript Error Tracking

12% of pages load with errors.
About 0% are reported by users.

Every minute people are left frustrated by broken software. It doesn't have to be like this.

CatchJS tracks any JavaScript error that happens on your site, and notifies you when new problems happen.

See the code where the error happened. Source maps are automatically applied.
See Core Web Vitals for all your pages.
Performance Monitoring

Everyone wants fast websites, but everyone keeps building slow websites.

Page speed affects both search engine rankings and user happiness.

The first step in building a fast site is to measure what's slow.

Know about performance problems by tracking the real speed experienced by your users.

Private Analytics

Track how your site is used, without tracking your users.

Simple analytics is included, that respects user privacy.

No need for cookie consent pop-ups.

No advertising giant tracking your users.

See what content is popular, and what it isn't, by the pages' pageview counts.
