GraphQL vs. REST
Flexible Queries vs. Predictable Endpoints
GraphQL offers flexible queries and reduces over-fetching. REST is simpler, more cacheable, and battle-tested. The choice depends on your data graph complexity.
📊 Scoring Matrix
Single query, exact fields
Multiple endpoints, fixed response
Complex (query-level)
Simple (HTTP-level)
Schema, resolvers, types
HTTP verbs, status codes
Eliminated by design
Common without versioning
Rich (Apollo, Relay)
Universal (any HTTP client)
N+1 query risk
Predictable per-endpoint
📋 Executive Summary
Use GraphQL for complex, relationship-heavy UIs with many different views. Use REST for simple CRUD, public APIs, and when caching is critical.
GraphQL can reduce frontend API calls by 60–80% but increases backend complexity by 30–40%. Net ROI depends on frontend/backend team ratio.
🎯 Decision Framework
- ✓ Multiple clients with different data needs
- ✓ Complex, nested data relationships
- ✓ Rapid frontend iteration
- ✓ Mobile apps needing minimal data transfer
- ✓ Public APIs consumed by third parties
- ✓ Simple CRUD operations
- ✓ High cacheability requirements
- ✓ Teams without GraphQL expertise
GraphQL if: multiple clients (web, mobile, partner) with different data needs. REST if: single client, public API, or high-cache requirements.
🌐 Market Context
35% of companies use GraphQL in production (2025). Growth has plateaued as teams discover the operational complexity. REST remains dominant for public APIs.
GraphQL adoption peaked in 2023. Many teams are now adopting hybrid: GraphQL for internal APIs, REST for external. tRPC is emerging as a type-safe REST alternative.
