h3-masque is an implementation of the CONNECT-UDP protocol RFC 9298, based on h3 and MsQuic. It provides both a client and a proxy implementation. It also supports the Proxying Bound UDP in HTTP I-D.
h3-masque is very early prototype with no thorough testing, poorly documented, and very poor error and edge case handling.
