quiche is Cloudflare's Rust implementation of the QUIC transport protocol and HTTP/3 as specified by the IETF. It exposes a low-level API for processing QUIC packets and managing connection state, with the application responsible for I/O and event loops.

Use cases

• add HTTP/3 support to a server or edge network
• implement a QUIC client or server in Rust
• integrate HTTP/3 into curl
• implement DNS over HTTP/3
• experiment with the QUIC transport protocol

When to choose

• you need a production-proven QUIC/HTTP-3 implementation (powers Cloudflare's edge)
• you want a low-level QUIC API with full control over I/O and event loops
• you're building in Rust or integrating via C FFI (e.g., curl, Android)

When to avoid

• you need a batteries-included HTTP server with built-in socket handling
• you only need HTTP/1.1 or HTTP/2
• you want the bundled example apps for production use (they are explicitly not production-ready)
