I wouldn't use this, because it seems odd to use a Cloudflare Worker for something inherently static, but I thought about what I might use, and bunny.net came to mind. Now I have a question, which is why on the Bunny.net pricing page doesn't it mention Cloudflare? https://bunny.net/pricing/ It mentions CDN77, BytePlus, CacheFly, CloudFront, and Fastly. Is what Cloudflare provides in a different market segment?
Cloudflare's pricing is "free until you get a message from the sales team that it's time to pay up". That's impossible to compare to anything else, so yes effectively a different market segment.
