G3M vs RimSort

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.

RimSort is a free, GPL-3.0 community mod manager and sorter for RimWorld, with Windows, macOS, and Linux support. It orders mod lists from mod data, community rules, and Steam data, while detecting conflicts and warning about missing dependencies or incompatibilities. Lists can be imported, exported, saved, and appended. SteamworksPy connects with the Steam client and can launch the game through the Steam API; the Steam Browser downloads Workshop mods through SteamCMD or the client, even without a Steam RimWorld copy. RimSort also handles Git-based mods and databases, shares logs through 0x0.st, and shares mod lists through Rentry.co. Its todds DDS encoder offers three texture-optimization presets. Database tools build, compare, merge, publish, and edit rules. Optional external metadata databases require separate configuration. Releases may trigger antivirus false detections, and Snap-installed Steam is unsupported on Linux.
