Some thoughts on how useful Anubis really is. Combined with comments I read elsewhere about scrapers starting to solve the challenges, I’m afraid Anubis will be outdated soon and we need something else.

And it was/is for sure the lesser evil compared to what most others did: put the site behind Cloudflare.
I feel people that complain about Anubis have never had their server overheat and shut down on an almost daily basis because of AI scrapers 🤦
Is there a reason other than avoiding infrastructure centralization not to put a web server behind cloudflare?
Yes, because Cloudflare routinely blocks entire IP ranges and puts people into endless captcha loops. And it snoops on all traffic and collects a lot of metadata about all your site visitors. And if you let them terminate TLS they will even analyse the passwords that people use to log into the services you run. It’s basically a huge survelliance dragnet and probably a front for the NSA.
Cloudflare would need https keys so they could read all the content you worked so hard to encrypt. If I wanted to do bad shit I would apply at Cloudflare.
Maybe I’m misunderstanding what “behind cloudflare” means in this context, but I have a couple of my sites proxied through cloudflare, and they definitely don’t have my keys.
I wouldn’t think using a cloudflare captcha would require such a thing either.
That’s because they just terminate TLS at their end. Your DNS record is “poisoned” by the orange cloud and their infrastructure answers for you. They happen to have a trusted root CA so they just present one of their own certificates with a SAN that matches your domain and your browser trusts it. Bingo, TLS termination at CF servers. They have it in cleartext then and just re-encrypt it with your origin server if you enforce TLS, but at that point it’s meaningless.
Oh, I didn’t think about the fact that they’re a CA. That’s a good point; thanks for the info.
Hmm, I should look up how that works.
Edit: https://developers.cloudflare.com/ssl/origin-configuration/ssl-modes/#custom-ssltls
They don’t need your keys because they have their own CA. No way I’d use them.
Edit 2: And with their own DNS they could easily route any address through their own servers if they wanted to, without anyone noticing. They are entirely too powerful. Is there some way to prevent this?
Yeah, I’m just wondering what’s going to follow. I just hope everything isn’t going to need to go behind an authwall.
The developer is working on upgrades and better tools. https://xeiaso.net/blog/2025/avoiding-becoming-peg-dependency/
I’ll say the developer is also very responsive. They’re (ambiguous ‘they’, not sure of pronouns) active in a libraries-fighting-bots slack channel I’m on. Libraries have been hit hard by the bots: we have hoards of tasty archives and we don’t have money to throw resources at the problem.
The Anubis repo has an enbyware emblem fun fact :D
Yay! I won’t edit my comment (so your comment will make sense) but I checked and they also list they/them on their github profile
Cool, thanks for posting! Also the reasoning for the image is cool.
Unless you have a dirty heatsink, no amount of hammering would make the server overheat
Are you explaining my own server to me? 🙄
What CPU do you have made after 2004 that doesn’t have automatic temperature control ?
I don’t think there is any, unless you somehow managed to disable it ?
Even a raspberry pi without a heatsink won’t overheat to shutdown
You are right, it is actually worse, it usually just overloads the CPU so badly that it starts to throttle and then I can’t even access the server via SSH anymore. But sometimes it also crashes the server so that it reboots, and yes that can happen on modern CPUs as well.
You need to set you http serving process to a priority below the administrative processes (in the place where you are starting it, so assuming linux server that would be your init script or systemd service unit).
Actual crash causing reboot ? Do you have faulty ram maybe ? That’s really not ever supposed to happen from anything happenning in userland. That’s not AI, your stuff might be straight up broken.
Only thing that isn’t broken that could reboot a server is a watchdog timer.
You server shouldn’t crash, reboot or become unreachable from the admin interface even at 100% load and it shouldn’t overheat either, temperatures should never exceed 80C no matter what you do, it’s supposed to be impossible with thermal management, which all processors have had for decades.
Great that this is all theoretical 🤷 My server hardware might not be the newest but it is definitly not broken.
And besides, what good is that you can still barely access the server through ssh, when the cpu is constantly maxed out and site visitors only get a timeout when trying to access the services?
I don’t even get what you are trying to argue here. That the AI scraper DDOS isn’t so bad because in theory it shouldn’t crash the server? Are you even reading what you are writing yourself? 🤡
Even if your server is a cell phone from 2015, if it’s operating correctly and the cpu is maxed out, that means it’s fully utilized and services hundreds of megabits of information.
You’ve decided to let the entire world read from your server, that indiscriminatory policy is letting people you don’t want getting your data, get your data and use your resources.
You want to correct that by making everyone that comes in solve a puzzle, therefore in some way degrading their access, it’s not surprising that they’re going to complain. The other day I had to wait over 30 second at an anubis puzzle page, when I know that the AI scrappers have no problem getting through, something on my computer, probably some anti-crypto mining protection is getting triggered by it and now I can’t no-script the web either because of that thing and it can’t even stop scrappers anyway !
So, anubis is going to be left behind, all the real users are, for years, going to be annoyed and have their entire internet degraded by it while the scrappers got that institutionally figured out in days.
If it’s freely available public data then the solution isn’t restricting access trying to play a futile arms race with the scrapper and throwing the real users to the dogs, it’s to have standardized incremental efficient database dumps so the scrappers stop assuming every website is interoperability-hostile and scrape them. Let facebook and xitter fight the scrappers, let anyone trying to leverage public (and especially user contributed data) fight the scrappers.
Aha, an apologist for AI scraper DDOS, why didn’t you say so directly instead of wasting my time?
Even if one would want to give them everything, they don’t care. They just burn through their resources and recursively scrape every single link on your page. Providing standardized database dumps is absolutely not helping against your server being overloaded by scrapers of various companies with deep pockets.
