Developer Tools comparison
Two of the best developer tools tools, compared side-by-side. Here’s how each one stacks up.
Run apps close to your users globally.
🎯 Why it’s useful
For latency-sensitive apps (collaborative tools, games, realtime APIs), Fly's multi-region deploy is uniquely simple.
💜 Why we like it
The CLI-first developer experience. `fly launch` from any folder gets you a URL in 90 seconds.
The open-source Firebase alternative.
🎯 Why it’s useful
Generous free tier. You can ship an MVP with auth + DB + file storage without writing a backend.
💜 Why we like it
It's real Postgres. When you outgrow the SaaS, you can lift-and-shift to your own infra.
