The REST vs GraphQL debate is mostly settled—use the right tool for the job.

REST Still Works

REST isn’t dead. It’s boring, predictable, and works everywhere:

GET /api/users/123
POST /api/users
PUT /api/users/123
DELETE /api/users/123

Advantages:

  • HTTP caching works out of the box
  • Every developer understands it
  • Tooling is mature (Swagger, Postman, etc.)
  • CDNs handle it perfectly

Use REST when:

  • Your API is simple CRUD
  • Mobile clients need caching (battery life matters)
  • You want HTTP-level security/monitoring

GraphQL Shines in Specific Cases

GraphQL solves real problems:

query {
  user(id: "123") {
    name
    posts(limit: 5) {
      title
      comments { author }
    }
  }
}

One request, exactly what you need. No over-fetching, no under-fetching.

Use GraphQL when:

  • Multiple client types need different data shapes
  • You have complex, nested relationships
  • You want strong typing + auto-documentation
  • Backend for Frontend (BFF) pattern fits

The Hybrid Approach

Many successful APIs use both:

  • REST for simple CRUD
  • GraphQL for complex queries
  • gRPC for service-to-service

Don’t be dogmatic. Mix and match.

Practical Advice

Start with REST. Add GraphQL only if:

  1. Multiple mobile apps want different data
  2. Over-fetching causes real performance issues
  3. Your team understands GraphQL complexity

GraphQL isn’t magic—it’s a trade-off. More flexibility, more complexity.

Conclusion

REST is the default. GraphQL is for specific problems. Both have their place.

Focus on solving user problems, not following trends.
