A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
No spam posting.
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
No trolling.

I'm running a website that is getting a lot of bot traffic and found Cloudflare free rule tier to be a bit limiting. (5 custom rules with length limits)
Ive got subnets for major VPS providers to block and will run analysis against my traffic to build on these lists.
What do others do?
I'm contemplating my Cloudflared tunnel into Crowdsec to my app.
Edit: Adding in image of my analysis of the IPs scanning for vulnerabilities.

You can set
dbpurgeageto30dand pretty much just run it--or you can setupjail.confwith abantime.factor. Its appeal is that you basically can download it, enable it, and it just works for you. It depends on your environment, though. If you have incoming authorized requests from other services it might be a pain to configure, but I've never used anything easier to protect you from bad actors.fail2ban isn't a WAF?
fail2ban can be configured in just about any way you want. There's no reason to say that fail2ban "isn't" a WAF simply because it wasn't designed that way. It's kinda moot when it can be configured that way.
