Type-safe HTML templating language for Go with compile-time safety
tRPC delivers end-to-end TypeScript type safety with no codegen — still the cleanest DX in TS monorepos in 2026. Rated 82/100.
tRPC is the open-source TypeScript framework that lets a Next.js, Express, Fastify or Bun server expose typed procedures and have those types flow into a React, React Native or Vue client with zero schemas, zero codegen and zero generated SDKs. We rate it 82/100 — for full-stack TypeScript monorepos, tRPC v11 is still the cleanest end-to-end developer experience on the market, even as Server Actions and TanStack Start chip away at its core pitch.
tRPC was created in 2020 by Swedish developer Alex "KATT" Johansson, building on a tiny ZodRPC proof of concept by Zod author Colin McDonnell. The core idea is almost unfair: define a server router as a plain TypeScript object, import its type on the client, and TypeScript inference does the rest — autocomplete, parameter validation, return-type narrowing, error types — all without a single OpenAPI file, GraphQL schema or generated client.
The project is MIT-licensed, lives at github.com/trpc/trpc with around 40,000 GitHub stars, and ships its current major version, v11, since . The 2026 release line (v11.13.x → v11.14) added OpenAPI JSON generation for any tRPC router, a `streamHeader` option for `httpBatchStreamLink`, and a documentation revamp.
Sentiment in TypeScript circles is positive but increasingly nuanced. On Hacker News, builders shipping production apps describe tRPC in glowing terms — one commenter on the v11 launch thread wrote that they had used it across two roughly 50,000-line web apps and "love it." Reddit threads on r/typescript and r/nextjs repeatedly praise the way tRPC eliminates the "API contract" as a separate artifact. Recurring criticisms are real, though: GitHub Discussion #2448 catalogues TypeScript IDE slowdowns on routers with around 40 endpoints and heavy Zod schemas; Issue #5249 documented an 18 KB bundle-size regression between v10.44.1 and v10.45.0; and Discussion #1860 captures a long-running gripe that tRPC essentially assumes a TypeScript monorepo, so non-monorepo users end up publishing private npm packages of types just to share a router. Most pointedly, mindshare is shifting — one HN comment titled "I'm currently in the process of removing tRPC from our codebase" framed Server Actions and TanStack Start server functions as good-enough replacements for simple Next.js apps. tRPC's defenders push back that those alternatives still don't match its caching, batching and multi-client story.
tRPC is free and open source under the MIT license. There is no commercial tier, no SaaS layer, and no enterprise upsell.

Best for: small-to-mid-size product teams shipping a TypeScript backend and TypeScript frontend in the same monorepo, especially when they already use React Query, Next.js or a Bun/Hono fetch-based runtime and want zero contract drift.
Not ideal for: public APIs that need a published spec, polyglot teams with non-TypeScript clients, very large routers where TS IDE performance matters, or simple Next.js apps where Server Actions plus a couple of validated mutations are enough.
Pros:
Cons:
Compared with GraphQL, tRPC trades cross-language tooling and introspection for pure TypeScript inference. Versus a REST + OpenAPI codegen workflow, tRPC removes the build step but loses a published contract. Hono RPC with the `hc` client is leaner and edge-native but ships a thinner ecosystem. Next.js Server Actions are zero-config for in-app mutations; TanStack Start server functions cover most of tRPC's territory inside a Start app. ts-rest and the newer oRPC are the contract-first challengers worth watching.
If you live inside a TypeScript monorepo and want the fastest possible iteration loop between a typed backend and a typed frontend, tRPC is still the answer in 2026 — and v11's SSE, RSC and TanStack Query work make it more capable than ever. If you're shipping a Next.js app where a few mutations and a public REST surface are the whole job, Server Actions plus a thin route handler will probably get you there with less ceremony. We score it 82/100: outstanding DX, real ecosystem pressure, and an open-source license that means trying it costs nothing.
