In their own words
G3M
G3M is a free, open-source desktop manager for GameMaker mods. It can browse supported GameBanana games and install mods from GameBanana, external URLs, local archives, or one-click links. Built-in game entries include DELTARUNE, DELTARUNE Demo, UNDERTALE, UNDERTALE Yellow, Pizza Tower, Sugary Spire, and FRICKBEARS3; users can also add custom games through its Game Manager.
Multiple library profiles can hold separate active mod selections and settings. The Mod Editor combines patches, file replacements, and archive contents, while other tools create and apply patches, merge patch sets, compare files, export diff reports, and convert supported formats. Supported games can launch directly or through Steam where available; Linux users can use PortProton for compatible Windows games. Its Catalog includes themes and plugins, including tools for DELTARUNE saves and custom save folders. Downloads are available for Windows, Linux, and macOS on x86_64 and ARM64 computers. The project states that normal launch mode restores game files after the game closes.
Prismo
Prismo publishes Zephyr, a free, open-source desktop mod manager for Linux, macOS, and Windows. Zephyr lets users browse, install, update, and organize mods for about 200 games. Built-in access combines Thunderstore and CurseForge browsing. Users can create and switch between profiles for each game, then share a profile through a code or link. Optional cloud synchronization uses Discord sign-in to synchronize profiles across devices. The app also includes an Archipelago multiworld randomizer with a bundled Python runtime, a configuration editor, gamepad navigation, and seven languages. Without sign-in, profiles, configuration files, and preferences remain on the device, while public mod metadata is requested anonymously. Cloud-enabled profile archives and metadata are stored with Prismo Studios’ hosting provider in France. Zephyr is licensed under GPL-3.0, with source code on GitHub. Installers include Windows .exe, Linux AppImage and .deb, and macOS .dmg files.
