API design in 2026: REST, GraphQL or tRPC?

There is no universally correct API style. The right answer depends on who consumes the API, how many teams own it, and how fast the surface changes.
REST is still the default
HTTP semantics, caching, and tooling ubiquity make REST the safe choice for public APIs and anything that crosses an org boundary.
GraphQL for complex frontends
Multiple clients, deeply nested data, and federated teams — GraphQL still earns its complexity here.
tRPC for full-stack TypeScript
When the same team owns both ends in TypeScript, tRPC removes a whole layer of glue code.
