Most analytics tools tell you how many people visited. They don't tell you the page broke for half of them. Datasense records JavaScript errors from real browsers with the same script that counts your visitors, so traffic and errors sit in one dashboard.
Free up to 5k events a month. No card.
Uncaught exceptions, unhandled promise rejections, failed scripts, images and stylesheets, and console.error calls. You can filter the list by kind.
Each error comes with its message, stack trace, page, browser, operating system, device and country. You see where it happened and for whom.
The same error from many visitors shows up as one row. It tells you how many times it happened, how many visitors hit it, which pages and browsers, and when it was first and last seen.
New errors appear while the page is open, without a refresh. The same dashboard shows visitors, sources and revenue, so you can tell if a drop in sales lines up with a new error.
Create a free account and paste one script tag into your site's <head>. It's under 3 KB.
Error tracking is on by default. There's no second SDK and no extra config. Errors start coming in with your first pageviews.
Click an error to see its stack trace and each time it happened. Export the list as CSV if you want to share it.
So you know before you sign up.
