Core Capabilities
End-to-End Safety
No external parsers. Route schemas drive the TypeScript inference entirely, preserving safety across the network bridge.
Built on Bun
Designed natively for Bun's extreme performance. Cold starts are lightning-fast with minimal overhead for every request.
Real-Time First
Subscriptions via WebSockets and SSE are treated like HTTP endpoints. Type-safe streams directly mapped to identical contexts.
Built-in Builder
Forget external dependencies. The native `h` schema builder seamlessly generates types and acts as a runtime validator automatically.
Plugins Architecture
Encapsulate logic beautifully. Any module export can be `.use()`d directly as a distinct application, enabling immense scale.
Auto-Swagger Docs
Your typing directly reflects the OpenAPI specification. Install a plugin to autogenerate pristine interactive documentation instantly.
