File-specific size monitoring
Wondering what part of your JS code just got larger? DebugBear will tell you exactly what file changed. If you have a JavaScript bundle with a hash in the file name DebugBear will detect that and track size changes for that bundle.
Access past page versions
Trying to figure out when a bug was introduced or how a feature used to work before? Load a fully interactive archive of the old page version in your browser.
How it works
Nothing to install
Just enter the URLs of the pages you want to monitor and we'll do the rest.
Automatic monitoring and alerts
DebugBear regulary loads and analyzes your site, either once a day or once an hour. If there's been a big change we'll let you know via email or Slack message.
