Celestial Client

A Minecraft client written from scratch in C++. It loads fast, keeps a steady frame rate, and runs every mod in a sandbox.

The Celestial Client title screen: Singleplayer, Multiplayer and Settings over a forest at dusk
Built from scratch.
A new engine in C++ with a Vulkan renderer. It starts fast and holds a steady frame rate on integrated graphics and high-end cards alike.
Your game as it is.
Always the newest Java Edition. Your worlds, servers, resource packs and shader packs work unchanged.
Mods in a sandbox.
Write them in Lua, C or C++. Each one runs in its own sandbox and only gets what it asks for.

Every feature in one place

Zoom, fullbright, a HUD you can rearrange, cosmetics and more live in one Features screen. They're all off until you turn them on, and none of them change how the game plays.

  • Search every feature and setting
  • Move and resize the HUD in an editor
  • A Fancy style or the vanilla look, your choice

  1. clight new lua my_modStart a project from a template
  2. clight runLaunch the game with your mod. Saving a Lua file reloads it
  3. clight build --releaseCheck it and pack my_mod-1.0.0.clmod
