Waiting for your writeup, especially the Bunny part. We moved away from AWS but Cloudflare remains a point of failure, we are going to remove it as soon as we have some spare time to do the required research.
Honestly my needs are not super complicated. There are a few edge rules I have in place to try and block things like the TikTok Bytespider which is hammering one of my sites. It's able to support round-robin multi-endpoint DNS, including weightings you can update which is super useful for what I'm doing. I've only really needed to speak to support twice so far; one was to get un-blocked because I migrated all my sites too quickly on a fresh account lol, so triggered their suspicious activity (so just be aware of that) - but both times they replied within an hour and resolved things.
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.
