I got into the self-hosting scene this year when I wanted to start up my own website run on old recycled thinkpad. A lot of time was spent learning about ufw, reverse proxies, header security hardening, fail2ban.
Despite all that I still had a problem with bots knocking on my ports spamming my logs. I tried some hackery getting fail2ban to read caddy logs but that didnt work for me. I nearly considered giving up and going with cloudflare like half the internet does. But my stubbornness for open source self hosting and the recent cloudflare outages this year have encouraged trying alternatives.
Coinciding with that has been an increase in exposure to seeing this thing in the places I frequent like codeberg. This is Anubis, a proxy type firewall that forces the browser client to do a proof-of-work security check and some other nice clever things to stop bots from knocking. I got interested and started thinking about beefing up security.
I'm here to tell you to try it if you have a public facing site and want to break away from cloudflare It was VERY easy to install and configure with caddyfile on a debian distro with systemctl. In an hour its filtered multiple bots and so far it seems the knocks have slowed down.
My botspam woes have seemingly been seriously mitigated if not completely eradicated. I'm very happy with tonights little security upgrade project that took no more than an hour of my time to install and read through documentation. Current chain is caddy reverse proxy -> points to Anubis -> points to services
Good place to start for install is here
Anubis is an elegant solution to the ai bot scraper issue, I just wish the solution to everything wasn't just spending compute everywhere. In a world where we need to rethink our energy consumption and generation, even on clients, this is a stupid use of computing power.
It also doesn’t function without JavaScript. If you’re security or privacy conscious chances are not zero that you have JS disabled, in which case this presents a roadblock.
On the flip side of things, if you are a creator and you’d prefer to not make use of JS (there’s dozens of us) then forcing people to go through a JS “security check” feels kind of shit. The alternative is to just take the hammering, and that feels just as bad.
No hate on Anubis. Quite the opposite, really. It just sucks that we need it.
What would you propose as an alternative?

Not having catgirls is def a con
No numbers, no testimonials, or even anecdotes... "It works, trust me bro" is not exactly convincing.
That blog post is fundamentally misunderstanding what Anubis actually does.
Imagine friends seeing catgirl on your browser and now you have to explain it to them who has zero knowledge in it
