Replacements

Listings that take over the same core job as ATLauncher.

  • Prism Launcher

    A Minecraft launcher that keeps every modpack in its own instance so one update cannot break the others.

    FreeOpen sourceWindowsmacOSLinux

    Prism Launcher also keeps modpacks in separate instances, installs from Modrinth and CurseForge, handles multiple Minecraft accounts, and is more polished for building packs by hand.

  • Modrinth App

    The official launcher for Modrinth, built around installing mods and modpacks in a couple of clicks.

    FreeOpen sourceWindowsmacOSLinux

    Modrinth App is built with Rust and Tauri instead of Java, starts quickly, but its catalogue is Modrinth only, so CurseForge packs must be imported by hand.

  • GDLauncher

    A free Minecraft launcher that installs mods and modpacks from CurseForge and Modrinth with one click.

    FreeProprietaryWindowsmacOSLinux

    GDLauncher offers one-click installs from CurseForge and Modrinth, supports Forge, Fabric, NeoForge and Quilt, and shares instances by code, but its source license is not stated.

  • MultiMC

    An alternative Minecraft launcher for managing multiple cleanly separated instances with their own mods and saves.

    FreeOpen sourceWindowsmacOSLinux

    MultiMC also isolates instances with separate mods and saves and gives fine control over Java runtimes, though recent releases are infrequent and it lacks built-in modpack browsing.

  • CurseForge

    A mod platform with a desktop app for finding and installing mods and modpacks for many games.

    FreeProprietaryWindowsmacOSLinux

    CurseForge is a closed-source desktop app that installs mods and modpacks for many games, but it is tied to the CurseForge catalogue rather than several sources.

  • Minecraft Launcher

    The official launcher for installing, updating and playing Minecraft Java and Bedrock editions and other Mojang games.

    FreemiumProprietaryWindowsmacOSLinux

    Minecraft Launcher is the closed-source official app that launches Java and Bedrock editions and snapshots, but it offers no modpack browsing or separate modded instances.
