What are you looking for? I use Bunny CDN along with Bunny Shield, and together they're better than Cloudflare for me. It's $10/month, but I can afford it for the privacy of my users. Bunny's aggressive bot blocking without bothering the vast majority of users with regular challenge pages provides a much better UX.

But Bunny Shield is not a Cloudflare WAF replacement afaik. Not even close.
