Why Your Next.js App Needs a Proper API Gateway

The Missing Piece in Most Next.js Deployments

Many Mumbai teams deploy Next.js directly to the edge — Vercel, Netlify, or Cloudflare — and add API routes inside the app itself. This works for small projects, but once you add authentication, rate limiting, and multiple microservices, you need a dedicated API gateway.

What an API Gateway Provides

• ›Unified authentication: JWT validation, API key checks, and OAuth flows handled in one layer
• ›Rate limiting: Prevent abuse before it reaches your application servers
• ›Request routing: Direct /api/v1/* to one service, /api/v2/* to another, without app-level routing logic
• ›Response caching: Cache frequently accessed API responses at the gateway level

When to Add a Gateway

Add a gateway when: you have more than 3 backend services, need per-endpoint rate limiting, or require different authentication strategies for different routes.

A Mumbai SaaS platform we worked with added Kong as their gateway and reduced API latency by 40% through response caching alone.
