What makes Fly different is we manage the servers for you. All you do is run `fly launch` from the root of your project, then we take your Dockerfile (or generate one for you) and run it as a Firecracker VM on our very own bare metal servers. Waaay less layers and moving parts.
I don't see the point of docker:.VMs give maximum flexibility.Vercel/AWS Lambda gives max convenience. Docker is is this strange middle ground which only adds extra complexity š¤.

One of Fly's most powerful, less-talked about features is domains. You've probably seen the *.fly.dev domain, but did you know all apps have *.internal and *.flycast domains? Do you know what they do?. Watch & learn in just 5 minutes and 6 seconds.

Anyone want to tackle a project for us? We have a few bucks to spend.
@mrkurt @CollierAdam @flydotio @remix_run I'm honestly surprised nobody has written a Postgres wire protocol compatible wrapper for SQLite. It'd be nice to have a private port that you could run `psql` over Wireguard to query a SQLite database. It doesn't even sound *that* hard to implement.
