ct-main
The module host: scanning, dependency sorting, the service registry, the welcome window, and the command dispatcher.
Every line is public.
The complete source of CT-Main and all 13 feature modules is published on this site — browsable file by file, or as one archive.

Read the code online
The code/ folder on this site mirrors the repository exactly: one folder per Maven module, with its pom.xml, manifest, tests, and every Java file.
installer & versions
Verified downloads, asset planning, the runtime installer, and the official version catalog.
launcher & rules
Argument expansion, JVM flags, profile routing, and Mojang rule evaluation.
accounts
Device code sign-in through Xbox Live and Minecraft services, plus the offline profile.
theme & console
The hand-drawn dark interface: every visible control painted in-project, no look-and-feel dependency.
ctloader & modman
The CT mod API, dependency-ordered mod loading, and the mod manager for the mods folder.
Build
Build it yourself
The build needs JDK 21 or later and nothing else — the Maven wrapper downloads the rest on first use.
unzip CT-Platform-4.3.0-src.zip
cd CT-Platform-4.3.0
./mvnw packageThe build produces ct-main/target/CT-Main-<version>.jar and one jar per module in ct-module-*/target/. All unit tests run during the build; the same commands that verify a release are the ones you run at home.
To run your own build, point CT-Main at a modules folder:
mkdir modules
cp ct-module-*/target/ct-module-*.jar modules/
java -jar ct-main/target/CT-Main-<version>.jar --modules-dir modulesLicense
Terms
CT's own code is open source; read the license page for the exact terms. The only third-party dependency is Gson, shaded into CT-Main and the CT loader jar; its license is included in the source archive. CT downloads Minecraft files only from Mojang's official endpoints and never distributes game content.
