TL;DR
I no longer recommend Railway as the default platform for serious production workloads after its recent pattern of platform-level incidents.
Vercel is a strong exit path if your app is frontend-heavy, Next.js-first, or relies on lightweight serverless APIs, because it can reduce how much of your customer experience depends on Railway.
Vercel cannot directly replace Railway for persistent WebSocket servers, long-running workers, heavy Docker workloads, or platform-hosted databases.
Railway and Vercel have inverted cost mechanics. Railway bills usage around provisioned compute resources, while Vercel charges around request-driven usage, function duration, and active compute.
