I think these kind of requests can not be blocked. It is like asking if Claude computer control can be blocked from visiting websites. It is not detectable.
You could ofc display captchas which are difficult to solve for an AI.
As mentioned, browser-use doesn't seem "out of this world" hard to fingerprint since all instances would be using the exact same settings.
Browser-use just switched to patchright https://github.com/Kaliiiiiiiiii-Vinyzu/patchright which is an “undetectable” version of Playwright and can rotate/randomize fingerprints. Another extension uses residential proxies and pulls real fingerprints of real people.
Sorry if I'm missing something, but why can't Anubis not detect/block such AI agents? Is it because they use headful browsers?
Yes, they are doing the Proof of Work. If need be, we will completely emulate human-like mouse movements. These are essentially clients no different from real users.
But the thing is, the more they push for this, the less accessible websites will get, so there has to be another solution. Not everyone uses a mouse.
