But you haven't matched the experience

The hierarchy of needs for a website might look like

and we have accessibility (many unblocked platforms) and usability (decently fast), but we don't have any of the others. We don't have functionality - nothing's easy to use and deploy to yet. We don't have scalability - it's hard to support multiple apps. And we definitely don't have invisiblity - we're a while from the platform disappearing into the background.

The annoying thing is we're almost there

but we haven't matched the experience quite yet.

So at this point there are 5 workarounds we can deploy:

• Monoliths. Combine services and apps into one, so you only need to deploy it once. If a free tier only lets you deploy one app or gives you terrible cold starts, a monolith would easily offset them. (Needs to be combined with another domain provider to reseparate.)
• Use another static host. Then you can stop caring about how the compute provider charges for bandwidth or how they name their subdomains.
• Use a free domain. This means playing a lot of feeble games, but it could work; not sure.
• Use a paid domain. If you can pay for it and get it unblocked, you now own a part of the internet where you don't need to worry about the free default subdomains. You can even get back to Cloudflare.
• Get off the free tier. This one is really just for Fly, but you could start separating apps and disabling scale to 0 and tank the cost.

At this point, I know what to do (click on each provider to see which workarounds I might use), and I think I'm ready to match the experience.
