I'm curious what you use for a database on Fly.io. When I last looked into it, a proper managed database option was the last thing that they were missing from what I wanted.
I'm not skin in the game on either company but I know that they partnered with Supabase for awhile on this. I'm not sure if that partnership is ongoing or not.
Not first party, but they offer integrations with Neon, Supabase, PlanetScale, and Crunchy Bridge for managed pg.
Their “you’re on your own” option is really nice though for cheap, non-mission-critical stuff, and you can even scale the compute to zero during inactivity and just pay the attached volume costs.
Supabase would be a good pick. Vercel and Cloudflare both do SQL DBs now too, curious how they are. Neon seemed interesting, haven’t heard much about them in a while.
None of those integrated of course, but easier than going big cloud or self hosted
(I work at Vercel) We got rid of this and made it the same price as using Neon directly. We also added a bunch more database options (e.g. Supabase) https://vercel.com/marketplace
