OneClient
ModpackAll in one modpack for OneClient, the client for everyone
Description
OneClient
OneClient ships the most bleeding-edge mods, packaged with the best visuals out of any client, powered by OneConfig.
Performance
In the background, our competitors like Lunar Client and Feather/Dawn Client literally run an instance of Chromium in-game to power their GUIs.
Yes, clients actually are running Chrome IN YOUR MINECRAFT...
We use our own rendering library called PolyCompose (based on JetBrains Compose), resulting in drastically better visuals but also performance.
We package almost TWICE as many performance mods as Fabulously Optimized (27 vs 14 mods), meaning performance is significantly better in-game. And don't even get us started with Lunar/Feather...
User Interface
OneClient features a clean and sleek user interface, meticulously designed by actual designers. Optimized for looking good without sacrificing any easy of use. Supports themeing, so you can choose between what you prefer.

HUDs
We package our own HUD mods: EvergreenHUD and VanillaHUD, two of the best HUD mods ever created for Minecraft. On Hypixel SkyBlock, we support all the major SkyBlock mod HUDs, meaning all your favorite mods' HUDs show in one place.
Fully open-source
This should go without saying, but we are 100% open-source. We haven't had a single private repository on our GitHub since January 2026.
