At work I was asked by a different team how we can deal with bots, because someone in my team remembered that I knew how to do it.
I reluctantly suggested Anubis because I got shit for it last time, This is the URL https://anubis.techaro.lol/
This is the 2nd and last time I will ever recommend Anubis anywhere at work to deal with bots because of how unprofessional, un-serious and weird others perceive it.

The mascot being a ~10 year old “cutsie” anime cat girl is weird in a work setting.
I will never put myself in a situation again where I have to explain that it’s not weird to anyone again, same for that URL.
What is a professional looking open-source alternative to Anubis?


That is not always possible, or worth the fight.
Even if I was willing to go through all of that, not everyone is, so what happens is more people turn to cloudflare instead of something Foss
Sounds like you work with a bunch of short-sighted, judgemental simpletons who cannot look past initial aesthetics for a product that has nothing to do with aesthetics.
Tbh I would run far the fuck away from that company if they can’t be bothered to sit down for a meeting where you explain that it’s an open-source project run by an extremely small team of nerds and that there is a commercial product available without the branding issues.
Everything you’re describing about your employer/coworkers gives me giant red-flag warnings regarding their decision making process.
Time to start looking for a new employer, or accept that they’re idiots and next time they ask about bots tell them “I’ve tried explaining this already but you dismissed me for silly reasons, so go pay for CloudFlare and stop bothering me”.
