Introduction

Swift Rust is a full-stack React framework powered with Rust + Bun that combines the developer experience of Next.js with the performance and safety of Rust. Write your app in TSX, render with a Rust core, and ship a single statically-linked binary — 10x faster than Next.js.

What you'll build

This is a complete framework, not a renderer. It includes routing, layouts, data fetching, image and font optimization, video embeds, PDF generation, error handling, metadata, code splitting, and a CLI for scaffolding and adding components.

Why a new framework?

We love Next.js's developer experience — the file-based routing, the layout system, the data fetching primitives. But we wanted to ship a single binary with no Node.js runtime, and we wanted to keep the option of full-WASM SPAs without a different framework. Swift Rust is the result.

Key features

  • Native Rust HTTP Server & Radix Router: Built on Axum, Hyper, and matchit with 21ns route dispatch and sub-3ms cold starts.
  • Embedded JavaScriptCore C-FFI & WASM Navigator: In-process C-ABI JSX evaluation on the server and a compiled WebAssembly SPA router in the browser.
  • SafeHtml Cryptographic Boundary: Replaces insecure dangerouslySetInnerHTML with HMAC/BLAKE3 origin verification that allows signed server/codebase markup while blocking unauthenticated browser XSS injections.
  • Server Actions & Partial Prerendering (PPR): Full support for "use server" mutations, progressive <Form>, "use cache", revalidateTag, and streaming PPR shells.
  • Four rendering modes: pure SSR, SSR with WASM hydration, SSR with HTMX, and full WASM SPAs (plus pure-Rust UI components).
  • 2,071 Google fonts & bundled local fonts with automatic subsetting and size-adjust fallbacks.
  • Image, Video, Script & PDF components: Built-in AVIF/WebP <Image>, HTML5/YouTube/Vimeo <Video>, priority <Script> strategies, and declarative <Document> PDF generation.
  • 50+ shadcn-style UI components added with one CLI command: bunx @swift-rust/ui add button card input.
  • Single binary & Vercel BOA v3 deploy: swift-rust build emits both a standalone binary and zero-config .vercel/output in milliseconds.
