GDLauncher Carbon
GDLauncher released a rewrite called "GDLauncher Carbon" which changed the architecture and moved parts of the codebase to closed source. This caused some community members to switch to Prism Launcher.
Mod Management
Both launchers support browsing and installing mods from CurseForge and Modrinth within the app. Prism Launcher additionally supports ATLauncher modpacks and has more granular mod version management.
Which Should You Choose?
- Prism Launcher if you want open source, lightweight, and maximum control
- GDLauncher if you prefer a more visual interface and are familiar with it
Both are solid choices. Prism Launcher has become the community favorite in 2026 due to its open source nature and lightweight performance.
