Volga

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.

Why Volga?

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

Features

• HTTP/1 and HTTP/2 support
• Explicit and robust routing
• Composable async middlewares
• Dependency Injection without derive macros
• Typed request extraction
• WebSockets and WebTransport
• Streaming-friendly HTTP
• Full Tokio compatibility
• Runs on stable Rust 1.90+

Getting Started

Dependencies

[dependencies]
volga = "0.8.1"
tokio = { version = "1", features = ["full"] }

Simple request handler

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.

Performance

Tested on a single instance with 4 threads and 500 concurrent connections:

OS: Arch Linux
CPU: Intel i7-8665U (8) @ 4.800GHz
RAM: 31686MiB
