REST vs GraphQL vs tRPC 2026: What to Actually Use

A practical decision framework for choosing between REST, GraphQL, and tRPC in 2026, grounded in real project experience. The author argues that comparison tables are misleading because they ignore actual project constraints. REST remains the best choice for public APIs due to universal tooling and HTTP caching. GraphQL shines for complex relational data with multiple client types but adds significant operational overhead. tRPC is the top pick for TypeScript-only full-stack monorepos due to zero-cost type safety and developer experience. The recommended approach is multi-protocol: REST for public surfaces, tRPC or GraphQL for internal frontend-backend communication, and gRPC for service-to-service. The core message is to choose based on constraints (who consumes the API, data model complexity, team knowledge, scaling trajectory) rather than hype.
