GraphQL vs REST API
2026년 올바른 도구 선택을 위한 상세 비교
🏆 빠른 결론
무승부! 둘 다 훌륭한 선택입니다.
GraphQL excels when clients need flexible data fetching and you have complex, interconnected data. REST is simpler, better cached, and ideal for straightforward CRUD APIs.

GraphQL란?
GraphQL is a query language for APIs developed by Facebook. It allows clients to request exactly the data they need, reducing over-fetching and under-fetching common with REST APIs.
✅장점
- •Clients request exactly the data they need
- •Single endpoint for all queries
- •Strong type system with schema
- •Real-time subscriptions built-in
- •Excellent developer tooling (GraphiQL, Apollo)
- •Self-documenting via introspection
❌단점
- •More complex to set up and maintain
- •Caching is harder than REST
- •N+1 query problem requires careful handling
- •Steeper learning curve
- •File uploads not natively supported
- •Rate limiting is more complex
REST API란?
REST (Representational State Transfer) is the most widely used architectural style for web APIs. It uses standard HTTP methods and is simple, stateless, and well-understood by developers.
✅장점
- •Simple and well-understood
- •Native HTTP caching support
- •Stateless architecture
- •Wide tooling and library support
- •Easy to debug with standard HTTP tools
- •Works naturally with CDNs
❌단점
- •Over-fetching and under-fetching data
- •Multiple endpoints to maintain
- •Versioning can be challenging
- •No standard type system
- •Documentation requires separate tools
- •No built-in real-time support

🏆우리의 추천
광범위한 분석과 테스트 후, 우리의 결론은 다음과 같습니다: GraphQL와 REST API 모두 생산성을 크게 향상시킬 수 있는 훌륭한 도구입니다. 최선의 선택은 여러분의 구체적인 요구 사항, 워크플로우, 우선순위에 따라 달라집니다.
GraphQL을 선택하세요:
You have complex data relationships, multiple client types (web, mobile) with different data needs, or need real-time subscriptions.
REST API을 선택하세요:
You're building simple CRUD APIs, need strong HTTP caching, or want maximum simplicity and the widest ecosystem support.
자주 묻는 질문
No. GraphQL is an alternative, not a replacement. Many companies use both: GraphQL for complex client-facing APIs and REST for simple internal services.
최종 결론: 무엇을 선택해야 할까요?
