Website Blocker Checker

Test if your website blocking tools are working effectively

How This Checker Works

Select the distracting websites you want to test below

Click "Test Selected Sites" to check if they're blocked

If a site opens, your blocker isn't working. If it fails to load, it's blocked ✅

Note: Due to browser security (CORS), we can't automatically test if sites are blocked. You'll need to manually click each link to verify your blocker is working.
