Deploying Next.js: Vercel vs Railway, and What to Set Up First

You've built the app; now it has to go live and stay live. Here's how I think about deploying Next.js, and the setup that prevents day-two headaches.

Vercel vs Railway

Vercel is the path of least resistance for Next.js — it's built by the same team, auto-detects everything, and handles the App Router's edge and serverless behavior natively. For a portfolio, marketing site, or most apps, it's the default.

Railway shines when your app is more than a frontend — when you want a long-running server, a database, background workers, and cron jobs living together. I run larger apps on Railway for exactly that reason: it's a full environment, not just frontend hosting.

The rule of thumb: frontend-heavy or static-leaning → Vercel; full backend with persistent services → Railway.

Set environment variables before your first deploy

Secrets, API keys, database URLs — these live in the platform's environment settings, never in your code. Remember the Next.js rule: only NEXT_PUBLIC_-prefixed vars reach the browser, and those are visible to anyone, so keep real secrets server-side.

Add your domain and analytics on day one

Point your custom domain early so you're testing the real URL. And wire up analytics immediately — you want visitor data from the first day, not retroactively. On Vercel, that's a one-line addition.

Deploy early, before it's "ready"

Environment-specific issues — fonts, caching, env vars — only show up in production. Deploy behind a password while building so these surface cheaply.

Takeaway

Vercel for frontend-leaning apps, Railway for full backends, env vars and domain and analytics configured up front, and deploy early to catch the real issues. Boring, reliable deploys are the goal.
