Measurement Search

Here you can find the last 1500 measurements. If you want to access the rest of the measurements, please use the API at api.captcha.wtf

You can click the ID of the measurements and see further details such as HTTP headers and the received HTML data. If you already have a specific measurement ID, you can view it's details at /measurements/details/ID

You can also use the search bar below to find a specific method, Tor Browser security level, exit node IP address, or CAPTCHA detection result. You can also enter multiple keywords to find various combinations.

Reminder: captcha.wtf is the IPv4 only domain and exit11.online is the IPv6 only domain used in the measurements. You might also use them for the search criteria.
