Fast, simple, and high-performance web framework for Rust, built on top of Tokio and hyper.
Volga is designed to make building HTTP services straightforward and explicit, while keeping performance predictable and overhead minimal.
💡 Status: Volga is currently in preview.
The public API may change while core abstractions are being finalized.

Volga focuses on clarity and control without sacrificing performance.
It avoids hidden behavior and framework-driven magic. Macros are used sparingly and primarily to reduce boilerplate. Handlers, middleware, and routing behave exactly as they look in code.
Volga is a good fit if you:
- Want simple and readable handler signatures
- Care about predictable performance and low overhead
- Need fine-grained control over the HTTP request/response lifecycle
- Work with streaming, WebSockets, or long-lived connections
- Prefer explicit APIs over code generation
- HTTP/1 and HTTP/2 support
- Explicit and robust routing
- Composable async middlewares
- Dependency Injection without derive macros
- Typed request extraction
- WebSockets and WebSocket-over-HTTP/2
- Streaming-friendly HTTP
- Full Tokio compatibility
- Runs on stable Rust 1.90+
[dependencies]
volga = "0.8.9"
tokio = { version = "1", features = ["full"] }use volga::{App, ok};
#[tokio::main]
async fn main() -> std::io::Result<()> {
let mut app = App::new();
app.map_get("/hello/{name}", async |name: String| {
ok!("Hello {name}!")
});
app.run().await
}This example demonstrates:
- typed path parameter extraction
- async request handlers
- minimal setup with zero boilerplate
More advanced examples (middleware, DI, auth, rate limiting) can be found in the documentation and here.
