Catch JavaScript errors before your users do
Add one `<script>` tag to your page and Uptime Assure automatically captures JS exceptions, failed network requests, and unhandled rejections — and reports them straight to your dashboard.
Everything you need
Purpose-built features that make console error monitoring reliable, fast, and easy to act on.
JS exception tracking
Captures uncaught JavaScript exceptions and unhandled promise rejections — the silent errors that break user workflows.
Failed network requests
Detects failed fetch and XHR requests (4xx/5xx) logged to the console — so broken API calls don't go unnoticed.
Error grouping & trends
Identical errors are deduplicated into groups with occurrence counts and daily sparklines so you can prioritise what matters.
One script tag to install
Copy a single <script src="..."> tag from your monitor settings and paste it into your page's <head>. No build step, no SDK.
How it works
One script tag — up and running in under 2 minutes.
Enable Console Monitoring on your monitor
Toggle "Console Monitoring" when adding or editing an HTTP/HTTPS monitor, then copy the generated script tag from monitor settings.
Add the script tag to your page
Paste the one-liner <script src="..."> into your page's <head>. The snippet intercepts errors and beacons them to Uptime Assure — nothing else required.
View errors on the monitor detail page
A dedicated Console Errors card shows each captured error with type, message, source file, and timestamp. Grouped errors show frequency trends over time.
