There's something about the tone and content of fly.io blog posts that makes it impossible for me not to root for them. (It also helps that the DX is so great.) I've only had a chance to deploy toy apps to Fly.io, nothing at scale, yet, but it checks all my boxes.
Fuck no. If you asked me whether I valued Fly.io more than my HN account, I'd have to think about it. I have, uh, an HN problem. We actually hoped not to see this post on the front page! We have a mode of writing for HN ("has to be interesting for people who will never use Fly.io") and there's a Fly Machines post in the works that fits that model. At any rate: I had very little to do with this post; if you liked it, you like Chris Nicoll, who writes for us professionally. And Kurt, of course, who wrote the original guts of this post, and also has been beating the Fly Machines drum inside of Fly.io for most of the last year.
The DX is great until you think of using their rest api (not for machines) and the link Google gives you to their docs is a very very incomplete page with even the base url obselete and you're left browsing the forum to understand why your requests don't work ;)
