Version: actix-web 4.x | MSRV: Rust 1.72+ | Source: https://actix.rs/docs

Actix Web is a powerful, pragmatic, extremely fast Rust web framework for building HTTP servers and web services. It supports HTTP/1, HTTP/2, TLS/HTTPS, WebSockets, and provides a type-safe request extraction and response system.

Key Benefits

• Extremely fast — one of the fastest web frameworks available
• Type-safe — extractors (FromRequest) and responders (Responder) provide compile-time guarantees
• Async by default — built on Tokio runtime
• Flexible routing — macro-based (#[get], #[post]) or manual web::route()
• Middleware system — composable Transform + Service traits, wrap_fn, from_fn
• WebSocket support — via actix-ws crate
• HTTP/2 support — automatic upgrade with TLS
• Static file serving — via actix-files crate
• CORS support — via actix-cors crate
• Session management — via actix-session crate
• Actor framework — actix crate for actor-based concurrency (WebSocket endpoints)
