HYSTERIA2
About HYSTERIA2
Hysteria2 redesigns the original Hysteria around a standard QUIC stack so the connection behaves like HTTP/3 traffic. Authentication is a simple password carried in the URI userinfo, optional Salamander obfuscation can mask the QUIC fingerprint, and the connection is tunable between friendly and brutal congestion control. Because it runs over UDP it avoids TCP head-of-line blocking and performs well on poor networks, at the cost of being blocked wherever UDP is denied. The Hysteria2 guide covers the share-link fields.

Frequently asked questions
What is Hysteria2?
Hysteria2 is a QUIC-based proxy protocol. A record contains a password, a server, a UDP port and optional TLS or masquerade settings.
How is Hysteria2 different from TCP-based protocols?
It runs over QUIC/UDP instead of TCP, which changes how records behave in the wild — port hopping and high port numbers are common in public shares.
Which formats support Hysteria2 exports?
Raw hysteria2:// links, base64 feeds and sing-box JSON include Hysteria2 records; Clash-format support depends on the client version.
