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.
Zephyr
Zephyr is a free desktop mod manager for browsing and installing mods, then switching between game mod profiles. It supports about 200 games out of the box and combines Thunderstore and CurseForge browsing in one search. Mods are deployed by copying them, and users can share a profile code or link so friends can reproduce a setup. Optional cloud sync requires signing in with Discord and enabling the feature. Zephyr also includes an Archipelago multiworld randomizer with Python bundled, a BepInEx configuration editor, and gamepad navigation throughout the interface. Customization includes seven themes, custom fonts and colors, and seven language options. The app is available for Windows, macOS, and Linux, and is distributed under the GPL-3.0 license. The maker says that without sign-in, personal data stays on the device and mod metadata requests are anonymous. With cloud sync enabled, profile archives and metadata are stored with the maker's hosting provider in France. The Windows build is not code-signed and the macOS build is not notarized.
