Only installed GTNH versions appear in your library. Add new instances when you are ready — no clutter from packs you do not use.
Detects Java on PATH, JAVA_HOME, and common install paths. Override per instance when a pack needs Java 8 or 17.
Sign in with your Microsoft account. OAuth in the browser with device-code fallback, plus automatic token refresh.
Live stdout and stderr from every launch, persisted per instance so you can debug without digging through log folders.
Workflow
Browse stable and beta GTNH releases from the official manifest and install with one click.
Set RAM, JVM arguments, Java path, and auth mode per instance. Theme the launcher while you are at it.
