Features

Celestial Client is a Minecraft: Java Edition client written from scratch in C++ with a Vulkan renderer. It plays the newest Java Edition, works with your worlds, servers, resource packs and shader packs, and runs mods written in Lua, C or C++ in a sandbox.

What's in it

A new engine

Written from scratch in C++ with a Vulkan 1.2 renderer. It is built to start quickly and hold a steady frame rate, on integrated graphics as well as dedicated cards.

The newest Java Edition

Celestial follows the newest Minecraft: Java Edition release. Gameplay, physics and network packets match vanilla, so servers see a normal client.

Your worlds and packs

Singleplayer worlds, multiplayer servers, resource packs and shader packs work without converting anything.

Client features in one place

Zoom, fullbright, a HUD editor, block outlines, a fog customizer, motion blur and more sit in one searchable Features screen. All of them are off until you turn them on, and none of them change how the game plays.

Fancy or vanilla look

Menus and the HUD come in a Fancy style or the vanilla look, with themes for the Fancy style.

Sandboxed mods

Mods use the CLight API and are written in Lua, C or C++ (C and C++ compile to WebAssembly). Each mod runs in its own sandbox with no native code, and only gets the permissions it asks for.

Mods checked before listing

Every mod file on this site is scanned and reviewed by staff before it is listed.

Launcher

The Celestial launcher signs you in with Microsoft, downloads the game files, keeps Celestial up to date and keeps separate instances for different mod sets.

Cosmetics

Capes, hats and other cosmetics made by creators, shown only to other Celestial players. They have no effect on gameplay or hitboxes.

What you need

  • A Minecraft: Java Edition account (the Celestial launcher downloads the game files itself)
  • Windows 10 or 11, 64-bit (macOS and Linux: coming soon)
  • A 64-bit x86 processor with AVX2 (Intel 4th generation or AMD Ryzen and newer)
  • Graphics with Vulkan 1.2: Intel HD Graphics 500 series, AMD Radeon HD 7000 series, NVIDIA GeForce GTX 900 series or newer; integrated graphics are supported
  • About 1.5 GB of free disk space

The full list is on the download page. How it compares with the official game: Celestial Client vs vanilla.
