An open source Lunar Client alternative
Lunar, Feather and AZ Launcher are PvP clients whose code is not published. Prism Launcher is open source, but it is an instance manager: it adds no in-game features. YuyuFrame brings both together: the code of the launcher and of the in-game agent is public, and it includes the modules you expect from a PvP client — keystrokes and CPS, zoom, freelook, 1.7 animations, armor HUD…
It is also a full launcher: vanilla, Fabric, Forge, NeoForge, Quilt, Modrinth and CurseForge mods and modpacks, multiple accounts. Each module is described on the modules page.
What YuyuFrame still lacks
- Windows only: no macOS or Linux version yet.
- Fewer modules than the biggest clients: 25, chosen for PvP and comfort.
- Targeted versions: the modules work on 1.8.9, 1.21.11 and 26.1 to 26.3, not on every version.
- An executable not yet signed with a publisher certificate: Windows shows a warning during install (explanation).
- No published performance numbers: until a reproducible benchmark protocol is online, we don’t claim any FPS gain.
- A young project, with a community that is still small.
