Editorial take
Why it stands out
Batching and HTTP limits differ by adapter—load-test before mobile launch.
Tool profile
Typesafe API framework for TypeScript apps that connects client and server without schema boilerplate.
Full-stack TypeScript teams avoiding GraphQL boilerplate
TypeScript-first remote procedure calls without codegen: share types between client and server, infer inputs/outputs, and ship quickly on top of HTTP.
tRPC is MIT-licensed open source. No usage-based tRPC fee—budget Next.js/Express/Fastify hosting, database access, and observability. Often paired with TanStack Query for caching.
Not a replacement for public OpenAPI contracts—pair REST/gRPC at system boundaries when other languages must consume your API.

Pricing snapshot
tRPC is free under MIT-style open-source licensing. There is no tRPC subscription or metered SaaS cost; your spend comes from whatever infrastructure runs the API layer, such as Vercel, Fly.io, AWS, or your own Node hosting.
