HYSTERIA
About HYSTERIA
Hysteria is a UDP-based proxy built on a customized QUIC stack, designed to keep throughput usable on lossy or throttled links. Its signature feature is brutal congestion control, which sends at a configured rate instead of backing off like TCP-friendly algorithms. Authentication uses an auth parameter or userinfo string, and optional obfuscation can disguise the UDP traffic. The protocol was superseded by Hysteria2, which simplifies the design, but first-generation endpoints still appear in public lists.

Frequently asked questions
Where do these records come from?
All records are collected from public sources — channels, websites, pastebins and repositories. Each record links back to the sources that published it.
What does freshness mean?
Freshness shows when a configuration was last seen in a public source. It is not a test result and does not mean the server is reachable.
How often is this page updated?
The index is refreshed continuously as sources are re-checked; these pages are regenerated every few minutes from the latest data.
Freshness shows when a config was last seen in a public source — not whether it works.
