Actix-web

Actix-web is the most performant web framework in the Rust ecosystem. Async handlers, middleware chains, extractors for typed request parsing, and WebSocket support — all with compile-time safety guarantees.

For Rust backend services, it's the default choice. We use it for microservices handling product sync, order processing, and API endpoints where throughput and reliability matter. The actor model heritage gives it natural patterns for concurrent workloads. Combined with SeaORM for database access, it's a complete backend stack.
