TsgcQUICServer — a raw QUIC transport server (RFC 9000): bind a UDP port, load a certificate and key, terminate TLS 1.3, and handle each QUIC connection and stream in an event so you can build your own protocol on top of QUIC, in Delphi, C++ Builder and .NET.
The listener half of the raw QUIC pair. Point it at a port and a PEM certificate, activate it, and answer connections and stream data in events. Built on the native OpenSSL 3.5 QUIC engine.
TsgcQUICServer
QUIC (RFC 9000) over UDP, TLS 1.3
Delphi, C++ Builder, .NET
Set the port and the certificate / key on QUICOptions, hook the QUIC events, then set Active. Reply on a connection's stream with WriteData.

Port and Active bind and release the UDP listener; Start / Stop do it explicitly.
QUICOptions.SSLOptions.CertFile and KeyFile load the PEM certificate and private key for the TLS 1.3 handshake.
OpenStream(aConnection) opens a server-initiated stream; the builtin engine carries several streams per connection.
WriteData(aConnection, …) writes a string or TBytes payload back to a client on a stream.
OnQUICConnect, OnQUICData, OnQUICStreamData, OnQUICDisconnect and OnQUICException handle the connection lifecycle and inbound bytes.
OnStartup and OnShutdown fire as the listener starts and stops.
