OneClient

# OneClient OneClient ships the most bleeding-edge mods, packaged with the best visuals out of any client, powered by [OneConfig](https://modrinth.com/mod/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](https://modrinth.com/modpack/oneclient-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.
