03.11.2026 · Compatibility not verified

↓ Choose a version
OneClient is an optimized Minecraft client featuring high performance, custom rendering via PolyCompose, and a clean user interface. It includes EvergreenHUD and VanillaHUD mods, supports SkyBlock HUD

An interface powered by OneConfig

OneClient is a modpack using OneConfig and its PolyCompose interface library, based on JetBrains Compose. Its interface supports theming.

Optimization as described by the author

The description lists 27 performance mods and compares that count with 14 in Fabulously Optimized. A component count is not an FPS measurement; this website does not provide its own benchmark results.

HUDs and the separate SkyBlock edition

The main pack names EvergreenHUD and VanillaHUD. For Hypixel SkyBlock, the author points to the separate OneClient SkyBlock pack, which describes support for other SkyBlock mod HUDs. Keep the editions’ files distinct.

Open source

The authors state that the project is fully open source and has had no private repositories since January 2026. Refer to the project and license for the selected release.
