Two modern app-hosting platforms with different defaults — a centralized usage-based PaaS with a polished deploy UX versus a multi-region container host that runs your app close to users.
Pick Railway when you want a centralized PaaS with usage-based billing and a tight deploy UX — the right call for side projects, prototypes, and small teams who want web, workers, and Postgres in one place without thinking about regions. Pick Fly.io when latency matters globally and you want to run your app and database close to users in multiple regions, and you're comfortable with a more infrastructure-flavored mental model than Railway's curated PaaS feel.
