Fly.io vs Railway
An honest, context-aware comparison. No affiliate links. No paid placements. Just the data that helps you decide.
Fly.io
Run full-stack apps as lightweight Firecracker VMs in 35+ regions worldwide — deploy by pushing a Dockerfile.
Railway
Modern cloud platform — deploy any stack in minutes without infrastructure expertise.
Side-by-Side Comparison
Objective metrics, no spin.
Teams needing multi-region latency without managing Kubernetes, or startups running AI inference on flexible GPUs.
Mission-critical databases without tolerance for occasional hardware reshuffles — Fly Postgres is unmanaged and requires engineering ownership.
Startups and indie developers who want the power of the cloud without DevOps overhead. Perfect companion to Vercel for backend services.
Teams needing complex networking, compliance controls, or advanced IAM — use AWS or GCP at that point.
