No trackers. No CAPTCHAs. No lockouts. Just a local classification based on our rules.
Paste a website URL, script URL, or domain. The checker will:
• Treat Cloudflare & Turnstile as Allowed.
• Treat anything matching our “abusive” script domains as Abusive.
• Otherwise mark it as Unknown.
Note: This tool checks domains against a local allowlist and blocklist only. Most websites will appear as Unknown because they are not included in either list. This is expected and does not indicate a problem.
Browser Notice: For the most accurate results, use Firefox with your uBlock Origin filters enabled. These filters determine which domains are classified as abusive. Filters can be updated at any time, and regions such as mainland China often block CAPTCHA providers entirely, so users there will never see CAPTCHA widgets.
