All in one modpack for OneClient by Polyfrost, the client for everyone. Optimized FPS / performance, world hosting, QoL features, in one place.
OneClient is a modpack made by Wyvest. It supports Minecraft 1.21 – 26.x. It has been downloaded 114,007 times on Modrinth. The last update came out on Nov 10, 2026.
OneClient ships the most bleeding-edge mods, packaged with the best visuals out of any client, powered by OneConfig.
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...
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.
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.
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.
Written by Wyvest. Read it with pictures on Modrinth.
This modpack runs on Fabric for Minecraft 1.21 – 26.x. The launcher you install it with sets that up for you.
Download the .mrpack file from Modrinth.
Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.
Give the instance enough memory: most modpacks want 4 to 8 GB.
To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
