GraphQL vs REST ComparisonFlexible queries vs simple conventions: the API design decision that shapes your entire stack

REST has been the default API approach since Roy Fielding defined it in 2000. GraphQL was open-sourced by Facebook in 2015 after they hit the limits of REST on mobile clients: too many round trips, too much over-fetching. Both are mature and production-proven. The choice between them has less to do with which is 'better' and more to do with your client complexity, team structure, and how many consumers your API has. For simple CRUD apps with one frontend, REST is usually enough. For complex product APIs with multiple clients, GraphQL starts earning its complexity.

Detailed comparison

Implementation simplicity
GraphQL
Higher complexity: schema, resolvers, DataLoader patterns required
REST
Lower: HTTP verbs and URL conventions are widely understood
Over-fetching
GraphQL
Eliminated: clients request exactly the fields they need
REST
Common: endpoints return fixed shapes regardless of what client needs
Under-fetching
GraphQL
Eliminated: single query can fetch nested data across types
REST
Common: multiple round trips needed for relational data
Caching
GraphQL
Complex: HTTP caching doesn't apply; client-side caching needed (Apollo, urql)
REST
Simple: HTTP caching, CDN, ETags work natively
Type safety
GraphQL
Excellent: schema is the contract; auto-generated types via GraphQL Code Generator
REST
Manual: OpenAPI/Swagger helps but requires discipline
Versioning
GraphQL
Not needed: schema evolves by adding fields, deprecating old ones
REST
Requires strategy: v1/v2 URL versioning or headers
Tooling & ecosystem
GraphQL
Good: Apollo, urql, GraphiQL, Hasura, but adds dependencies
REST
Excellent: Postman, curl, OpenAPI, every HTTP client works

Our verdict

We recommend: REST

REST is the safer default for most projects. It's simpler to implement, easier to cache, and has better tooling for documentation and testing. GraphQL is worth the investment when you have multiple clients (web, mobile, third-party) with diverging data needs, or when over-fetching and under-fetching are causing real performance problems. Don't add GraphQL's complexity without a specific reason.

When to choose each

Choose GraphQL when:

  • You have multiple clients (web, iOS, Android) with different data requirements
  • Your data model is highly relational and clients need to traverse relationships
  • You're building a public API where third-party developers will query it
  • Over-fetching is causing real mobile performance or bandwidth problems

Choose REST when:

  • You're building a simple CRUD app with one primary frontend client
  • Your team is small and GraphQL's learning curve isn't justified
  • You need HTTP caching at the CDN level for high-traffic read-heavy data
  • Your API will be consumed by non-JavaScript clients where GraphQL tooling is weaker
