About:
mvfst is Facebook's production-grade implementation of the QUIC transport protocol, designed for high-performance, low-latency network communication. It provides a robust, standards-compliant library for building applications that benefit from QUIC's features like multiplexed streams, improved congestion control, and reduced connection establishment time.
Key Features:
  • Full IETF QUIC protocol implementation
  • Optimized for high throughput and low latency
  • Integrated congestion control algorithms
  • TLS 1.3 integration for security
  • Extensive performance monitoring and diagnostics
Use Cases:
  • Accelerating web and mobile application traffic in large-scale services
  • Building custom client/server applications requiring modern transport protocols
  • Research and development of network transport technologies
Alternatives:
  • ngtcp2 – Another QUIC implementation, often used with nghttp3; mvfst is more tightly integrated with Facebook's ecosystem and performance tooling.
  • quiche – Cloudflare's QUIC implementation, powering their edge network; mvfst is Facebook's internal implementation optimized for their specific scale and use cases.
