Hypixel 1.21.11
Hypixel Utils, stats lookups, Urchin, Bed Wars team and upgrade widgets, Quick Play, LevelHead and the Hypixel helpers.
3 mods
Small Hypixel helpers: /who and gl when a game starts, hide messages (and other players' gg / gl), a limbo timer and auto-reply, boop back, welcome back for guild and friends, and auto-accept for party invites and friend requests.
Bind a key to queue one Hypixel game. Press the key anywhere on Hypixel and it sends that game's /play line for you — no chat, no typing. Pick a category, click a game to select it, then set its key in the Keybind field under the grid. Hypixel renames a mode now and then; the Command field edits the line the selected game sends.
Look any player up by name with /stats and /tag, from anywhere — including people who are not in your lobby. Sour answers these on the client, so Hypixel never receives the command.
