What tRPC does
tRPC is an open-source TypeScript library, first introduced publicly in May 2021 by creator Alex/KATT, that enables developers to build end-to-end typesafe APIs without code generation, schema definitions, or build steps. Its core architecture exploits TypeScript's native `import type` erasure to share type information between server and client at runtime with zero overhead: server procedures (queries, mutations, and subscriptions) defined in `@trpc/server` are consumed type-safely via `@trpc/client`, `@trpc/react`, or the newer `@trpc/tanstack-react-query` package. The framework is runtime- and framework-agnostic, with official adapters for Next.js, Express, Fastify, AWS Lambda, and a native Fetch API adapter that enables Cloudflare Workers, Deno Deploy, Vercel Edge Runtime, Astro, Remix, SolidStart, and Bun, supplemented by community adapters for SvelteKit and Nuxt.
The product portfolio consists of the four npm packages above plus community extensions (tRPC Panel, tRPC-OpenAPI, tRPC Devtools, tRPC Playground, ZenStack) and the create-t3-app scaffolder that bundles tRPC with Next.js, Tailwind, and Prisma. Composability is delivered through an immutable builder pattern (procedures, middleware chaining via `.pipe()` and `.concat()`, context extension), and integrations with Zod, Superjson, TanStack React Query, and AbortController round out the ecosystem. Production users include Google, Netflix, PayPal, and Mistral alongside startups such as Cal.com, Documenso, Langfuse, Legora, Ping.gg, and Pleo.
tRPC is MIT-licensed and distributed at no cost via npm and the GitHub repository. The only disclosed funding is non-dilutive: participation in the GitHub Accelerator program in April 2023, and ongoing operational support from GitHub Sponsors, with Silver-tier sponsorship from Greptile, CodeRabbit, and SerpApi plus smaller backers such as Ahoy Labs and Unkey. The project is maintained by a small core team (1–10 people) headed by creator Alex/KATT, with core contributors Julius Marminge, Nick Lucas, and former core member Sachin Raja. Major version cadence includes v10 in November 2022 and v11 in March 2025, with no commercial product, paid tier, or contractual customer relationship attached to the open-source distribution.

Product offeringCore offering
tRPC is an open-source TypeScript framework for building end-to-end typesafe APIs without code generation, build steps, or schema definitions. It uses TypeScript's native type inference to share types between client and server at runtime via the 'import type' feature. The product is distributed as an MIT-licensed library across npm, with official packages for server, vanilla client, React, TanStack React Query, and Next.js integrations, plus adapters for Express, Fastify, AWS Lambda, Cloudflare Workers, Deno, Vercel Edge, Astro, Remix, and other frameworks.
Product overview
tRPC is an open-source TypeScript RPC framework for building end-to-end typesafe APIs without code generation. The core offering consists of @trpc/server for building type-safe backend APIs with procedures (queries, mutations, subscriptions), middleware, and context handling; @trpc/client for consuming those APIs; and @trpc/tanstack-react-query (recommended) and @trpc/react for React integrations. Official framework adapters support Next.js, Express, Fastify, AWS Lambda, and the Fetch API standard (enabling Cloudflare Workers, Deno, Vercel Edge, Astro, Remix, SolidStart, Bun). A rich community ecosystem provides additional framework adapters (SvelteKit, Nuxt, Remix), developer tools (tRPC Panel, Devtools, Playground), the tRPC-OpenAPI extension for REST compatibility, and scaffolding tools like create-t3-app. The framework leverages TypeScript inference to provide automatic type safety across the client-server boundary.

tRPC competitors and assessment
Company assessmentOthers
- Zod: Zod is tRPC's recommended schema validation library and a deeply integrated part of the tRPC developer experience. It is also a partial substitute for end-to-end type safety, as some teams use Zod + REST instead of tRPC.
- Prisma: Prisma is the default ORM in the T3 Stack (alongside tRPC) and powers many tRPC codebases; it is also a partial substitute for tRPC's typesafe data layer when paired with tools like ZenStack or GraphQL generators.
- TanStack (React Query): TanStack React Query is tRPC's recommended data-fetching integration and a deep technical partner; it is also a partial substitute (developers could use TanStack Query with REST/GraphQL instead of tRPC), making it an adjacent/partner-as-competitor relationship.
Emerging players
- PostgREST: PostgREST serves a typesafe CRUD API directly from a Postgres schema, targeting a similar developer audience that wants to avoid hand-writing API layers. It is a partial alternative to tRPC for read-heavy internal APIs.
- Blitz.js: Blitz.js is a fullstack React/TypeScript framework that uses a typesafe RPC layer (zero-API) for client-server communication — directly inspired by and conceptually parallel to tRPC's approach, and built by adjacent community members.
Broad incumbents
- Supabase:
- gRPC: gRPC is the canonical typesafe RPC framework for polyglot backend services and competes with tRPC for the same conceptual slot (end-to-end typed API contracts), although it lacks tRPC's TypeScript-native developer experience.
- Hasura: Hasura auto-generates GraphQL/REST APIs from databases and competes for the same typesafe API layer that tRPC addresses, though it does so via a hosted engine rather than a code-first framework.
- GraphQL (Apollo): Apollo is the dominant GraphQL platform and the most established typesafe-API alternative to tRPC. tRPC is often evaluated as a 'lighter-weight internal-API' alternative to Apollo/GraphQL, and they compete for the same developer mindshare in full-stack TypeScript apps.
Direct peers
- WunderGraph: WunderGraph is a typesafe API framework that similarly aims to eliminate manual API contract work between frontend and backend, with strong GraphQL/TypeScript positioning. It is the most direct conceptual competitor to tRPC's typesafe-RPC approach.
