Comprehensive comparison to help you choose the right API architecture for your project
| Feature | REST | GraphQL |
|---|---|---|
| Data Fetching | Multiple endpoints | Single endpoint |
| Over-fetching | Common issue | Not a problem |
| Under-fetching | Multiple requests | One request |
| Learning Curve | Easy | Moderate |
| Caching | HTTP caching (easy) | Complex (needs tools) |
| Versioning | v1, v2, v3... | Schema evolution |
| Type Safety | Optional (OpenAPI) | Built-in |
| Tooling | Mature | Growing |
REST (Representational State Transfer) uses multiple endpoints, each returning fixed data structures. It's the traditional approach that's been around since 2000.
// Need user data? Make 3 separate requests
GET /api/users/123
GET /api/users/123/posts
GET /api/posts/456/comments
// Each returns ALL fields (even if you only need a few)
{
"id": 123,
"name": "John",
"email": "[email protected]",
"bio": "...",
"avatar": "...",
"settings": {...}, // Don't need this
"preferences": {...}, // Don't need this
// ... more unused data
}GraphQL uses a single endpoint where clients specify exactly what data they need. Developed by Facebook in 2012, open-sourced in 2015.
// One request, get exactly what you need
query {
user(id: 123) {
name // Only these fields
posts {
title
comments {
text
author {
name
}
}
}
}
}
// Nested data in one go, no over-fetchingThere's no universal winner. REST is simpler and battle-tested, perfect for most APIs. GraphQL shines with complex data needs and multiple clients. Many companies use both - REST for public APIs, GraphQL for internal services.
