tRPC vs REST API: Which Is Right for You?
tRPC provides end-to-end type safety between your Next.js front end and back end with zero code generation. REST APIs are more portable and support any client. tRPC wins for internal full-stack TypeScript projects.
Our Verdict
We use tRPC for internal full-stack Next.js projects where the API will only be consumed by our own TypeScript front end. We build REST APIs when the API is public, consumed by mobile apps, or needs OpenAPI documentation for external developers.
tRPC vs REST API: At a Glance
tRPC wins when…
- ✓ End-to-end TypeScript types from database to browser with zero generated code
- ✓ Any API change that would break the client is caught by TypeScript at compile time
- ✓ React Query integration gives you loading states, caching, and invalidation automatically
- ✓ No API documentation needed — TypeScript IS the documentation
REST API wins when…
- ✓ REST APIs can be consumed by any client in any language — not just TypeScript
- ✓ REST with OpenAPI provides discoverable, documented APIs for third-party developers
