rspc is a Rust framework for building typesafe web backends, inspired by tRPC, that lets you define routers with queries, mutations, and subscriptions in Rust and call them from a TypeScript client with end-to-end type safety. It integrates with Axum over HTTP/WebSocket and with Tauri via IPC, exporting TypeScript bindings from your Rust router.

Use cases

• build a typesafe API in Rust called from a TypeScript frontend
• tRPC-like end-to-end type safety with a Rust backend
• expose Rust backend logic to a Tauri desktop app frontend
• generate TypeScript bindings from Rust router definitions
• add middleware like auth and logging to typed API procedures

When to choose

• you want tRPC-style end-to-end typesafety with Rust on the backend
• you are building a Tauri app and want typed IPC between Rust and the web frontend
• you already use Axum and want typed procedures with minimal runtime overhead

When to avoid

• starting a new project - rspc is explicitly no longer maintained; look at its successor specta instead
• you need a general-purpose REST or GraphQL framework rather than RPC-style typed procedures
• your team does not use TypeScript on the frontend, since the main benefit is Rust-to-TS type safety
