Fly.io has GPUs now 2 years ago
I don't see any reason use Fly. There are more mature, feature-richer and cheaper solutions out there. We have the big complex ones like AWS, Azure, GCP, the easier more affordable all rounder like DO, Render, the hosting plattforms like Vercel, Heroku and finally the biggest bang for your money barebones like Hetzner.
Why should I choose Fly? How come they are so prominent on hackernews? Are they backed by VC and get their default 400 upvotes by backers? I get the impression that Fly posts here are kind of sponsored.
