REST vs GraphQL

Compare REST and GraphQL APIs: when to use each, trade-offs, and practical guidance.

REST uses multiple endpoints (GET /users, GET /users/1/posts) with fixed response shapes. GraphQL uses a single endpoint with flexible queries that request exactly the data needed. REST is simpler to implement, cache, and debug. GraphQL eliminates over-fetching and under-fetching, reduces round trips for complex data needs, and provides strong typing via schema. Use REST for simple CRUD APIs and public APIs. Use GraphQL for complex data relationships, mobile apps (bandwidth optimization), and internal APIs where frontend needs change frequently.
