CT v4.3.0

Every Minecraft Java version.
One precise launcher.

CT reads Mojang's official manifest, verifies every download with SHA-1, and launches releases, snapshots, legacy versions, and installed Fabric, Forge, and NeoForge profiles. Choose your track below — everything is searchable from the box in the header.

Download everything — one click CT-Main only v4.3.0 How installing works

The full download contains CT-Main, all thirteen feature modules, launcher scripts, and a read-me: unzip it, double-click Start CT-Main.command (macOS) or Start CT-Main.bat (Windows), and the launcher starts with every feature. Nothing to install by hand.
