LSQUIC Documentation

This is the documentation for LSQUIC 2.13.3, last updated Mar 23, 2020.

LiteSpeed QUIC (LSQUIC) Library is an open-source implementation of QUIC and HTTP/3 functionality for servers and clients. LSQUIC is:

  • fast;
  • flexible; and
  • production-ready.

Most of the code in this distribution has been used in our own products – LiteSpeed Web Server, LiteSpeed Web ADC, and OpenLiteSpeed – since 2017.

Currently supported QUIC versions are Q043, Q046, Q050, ID-25, and ID-27. Support for newer versions will be added soon after they are released.

LSQUIC is licensed under the MIT License; see LICENSE in the source distribution for details.
