Feature Comparison

Feature GraphQL REST
Data Fetching Client specifies fields Server determines response
Endpoints Single endpoint Multiple resource endpoints
Caching Custom (client-side) HTTP native (ETags, 304)
Type System Built-in schema Optional (OpenAPI/Swagger)
Real-time Subscriptions Webhooks, SSE, WebSocket
File Upload Multipart spec (complex) Native multipart
Learning Curve Moderate-Steep Easy
Versioning Schema evolution URL or header versioning

GraphQL

Best for: Applications with complex, nested data requirements and multiple client types (web, mobile)

Pricing: Free, open specification

Pros

  • + No over-fetching or under-fetching
  • + Single endpoint for all data
  • + Strong type system and schema
  • + Real-time with subscriptions
  • + Excellent developer tooling (GraphiQL)

Cons

  • - Caching is more complex
  • - N+1 query problem if not careful
  • - Steeper learning curve
  • - File uploads are awkward
  • - Security (query depth/complexity attacks)

REST

Best for: Simple CRUD APIs, public APIs, microservices communication, and teams new to API design

Pricing: Free, architectural pattern

Pros

  • + Simple and well-understood
  • + HTTP caching works natively
  • + Easy to implement and test
  • + Great tooling (Postman, Swagger)
  • + Stateless by design

Cons

  • - Over-fetching and under-fetching
  • - Multiple endpoints for related data
  • - API versioning challenges
  • - No built-in type system
  • - Documentation requires extra effort

Our Verdict

REST remains the best choice for most APIs, especially simple CRUD services, public APIs, and microservices. GraphQL shines when you have complex, nested data requirements or need to serve multiple client types efficiently. Consider starting with REST and migrating specific endpoints to GraphQL when the complexity justifies it.
