Railway vs Fly.io

Q: Which is better for for app-shaped http workloads — Railway or Fly.io?

Railway wins. Railway's DX is the right primitive for "deploy a Next.js + Postgres + Redis." Visual editor + per-second billing covers 80% of full-stack apps without operational depth.

Q: Which is better for for globally-distributed services — Railway or Fly.io?

Fly.io wins. Fly's 30+ regions and Postgres clusters with read replicas across regions are unique. Railway's US/EU region pair can't match. For latency-sensitive global apps Fly is the answer.

Q: Which is better for for stateful workloads with persistent volumes — Railway or Fly.io?

Fly.io wins. Fly volumes are first-class. Run databases, queues, ML model caches with persistent disk. Railway's volume story is thinner. For storage-heavy services Fly wins.

A side-by-side comparison from 59 GitHub-verified developers who shipped production code on both platforms.

TL;DR — The Verdict

Railway wins on visual DX and onboarding; Fly wins on global distribution, persistent volumes, and TCP/UDP support. For app-shaped workloads Railway; for stateful or globally-replicated services Fly.
