ATLauncher vs FTB App

ATLauncher is a Minecraft launcher for browsing, downloading and installing modpacks. Its catalog includes packs from ATLauncher, CurseForge, Modrinth and Technic, and it supports multiple mod loaders and pack imports. Users can maintain separate instances so a new installation does not affect an existing one; the launcher automatically selects the Java version for a pack.

The launcher supports multiple accounts, including Mojang and Microsoft accounts and Xbox Game Pass subscribers. Instance management can install mods, maps and resource packs from CurseForge and Modrinth. It also offers one-click save backups and tools to create and run servers for ATLauncher modpacks. ATLauncher is free and has downloads for Windows, macOS and Linux, as well as a Jar download. Playing modpacks requires a purchased Minecraft account. The site no longer accepts submissions for its own pack platform and recommends Modrinth or CurseForge for sharing packs. For help, users can turn to Discord; contact form requests needing a response are answered within 24 hours.

FTB App is Feed The Beast’s desktop launcher for finding and managing modpacks, then playing them. It is the officially supported way to get FTB modpacks, and it also connects to CurseForge for discovering and installing its packs. The app supports NeoForge, Fabric, and Forge, and lets users create and share their own modpacks or add, remove, and update mods. Packs stay in separate instances, with automatic updates and controls for Java version, arguments, and RAM. Users can install FTB modpack servers through the app or a Linux command line. The app runs on Windows, macOS, and Linux; Windows uses Overwolf, while the other desktop versions use Electron without another background application. It is free to use and contains ads supporting Feed The Beast. Authentication is required to use the app, and playing Minecraft requires a Minecraft account. Its source code is available through GitHub.
