Looking into ditching Cloudflare and still need a way to add bot protection and prevent AI crawlers on your websites? Anubis seems be a straight-forward solution to that, it has been added to SudoVanilla as of late April 2025 and is operating as expected.

Unfortunately, Anubis (together with similar projects like various Captchas etc.) is hardly any better than Clownflare from the perspective of end users who simply try to access the site and then have to wait for another 'check' to complete which can last for good 10 minutes and STILL fail... Seriously, what's wrong with today's internet? It's being completely ruined by this neverending, pointless war between the 'AI bots' and various highly intrusive and ineffective solutions to stop them (which also seem to be used to train said bots in the first place). Things have clearly gone haywire, and nobody seems to bother with the actual solution to break this vicious circle...

And in the end, it's the users who suffer most. Real people, for whom the sites were intended in the first place, are denied all access. They are the victims of this war, which has to stop.

What is Anubis?

Anubis weighs the soul of your connection using a sha256 proof-of-work challenge in order to protect upstream resources from AI scraper bots.

Anubis was used by: • UNESCO • The GNOME Project's GitLab instance • The Linux kernel mailing list archives and Git server • Wine • FFmpeg • sourceware.org • The Science Olympiad Student Center • Enlightenment • FreeCAD • ScummVM

Easy to Use Anubis sits in the background and weighs the risk of incoming requests. If it asks a client to complete a challenge, no user interaction is required.

Lightweight On average it uses less than 128 MB of ram.

Block the scrapers Anubis uses a combination of heuristics to identify and block bots before they take your website down. You can customize the rules with your own policies.

Installing and using this will likely result in your website not being indexed by some search engines. This is considered a feature of Anubis, not a bug.

This is a bit of a nuclear response, but AI scraper bots scraping so aggressively have forced my hand. I hate that I have to do this, but this is what we get for the modern Internet because bots don't conform to standards like robots.txt, even when they claim to.

In most cases, you should not need this and can probably get by using Cloudflare to protect a given origin. However, for circumstances where you can't or won't use Cloudflare, Anubis is there for you.
