This wiki tracks known implementations of QUIC. See also our Tools listing. Current interop status; make sure you are looking at or editing the correct tab.

Please add your implementation below. Keep sorted alphabetically. There are three sections, one for "IETF QUIC Transport", one for "HTTP/3C", and one for "QPACK". Entries may appear in multiple sections e.g. where a stack provides both IETF QUIC Transport and HTTP/3.

Note

If you are working on a QUIC implementation, please consider joining the QUIC Developers Slack Channel. Also, if possible, please set up a public server and publish its details below, so others can try and interoperate with your code.
