It's pretty easy to write your own. I made this one a while ago: https://github.com/chainguard-dev/crow-registry

https://github.com/cloudflare/serverless-registry

Well, Cloudflare does not launch anything. They acquire to build products. Look into all their recent product launches. They acquired a relatively small company and converted the founding team to a product team.

So, if you want them to build stuff, ask yourself, are there any "Docker Registry" startups out there. If jsdelivr/globalping is not keeping you busy enough... there is an idea

What would the business case be?
