FTB App vs Minecraft Launcher

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.

Minecraft Launcher is a free PC hub for accessing Minecraft games, downloading versions, reaching multiplayer servers, managing profiles, and getting mod support. It brings Java and Bedrock editions together on PC, though the games can also be launched without it. Players can use the latest versions and try snapshots, create one-click Quick Play shortcuts to favorite worlds, manage Java skins, and access account information. Settings include language and accessibility options, and the Launcher also shows Minecraft news and promotions. Installation is available through the Microsoft Store or the Minecraft download page. On Windows, installing from Minecraft.net still requires signing into the Microsoft Store with the account intended for the Launcher. A Microsoft account is required to play all Minecraft versions. The free Java and Bedrock trial includes the core Survival experience and about 100 minutes of in-game play, with duration varying slightly by device. It supports offline play and LAN multiplayer, but online multiplayer servers are disabled. Java Edition cross-play is limited to Windows, Mac, and Linux, while Bedrock supports cross-play across Windows, consoles, and mobile.
