Two usage-based cloud platforms with different defaults — a CLI-and-primitives approach versus a repo-first, visual-canvas workflow.
Here is how they line up as of 2026-07-29.
Fly.io and Railway both let you deploy apps and services and pay for what you use, but they start from different defaults.
Railway centers on connecting a Git repository and letting the platform read your code and configure the deploy, all viewed on a visual canvas.
Fly.io centers on the flyctl command line and a documented catalog of infrastructure primitives, from machines to managed databases and GPUs.
This comparison walks through how each platform handles deployment, pricing, databases, networking, and scaling, using each vendor page as of 2026-07-29.
Plan details and prices change often, so treat the figures here as a snapshot and confirm the current terms on each site before you commit.
At a glance In short Both are usage-based platforms for shipping apps.
Pick Railway to connect a repo and let the platform configure, preview, and roll back deployments from a visual canvas.
Pick Fly.io for CLI-driven control plus a documented catalog of Managed Postgres, GPUs, Kubernetes, and HIPAA-ready hosting.
