In short
G3M: Choose G3M when your games are built with GameMaker and you want one desktop tool for mod installs, profiles, patch creation, and launching. Since it is free GPL-3.0 software, there is no purchase decision, and releases support Windows, Linux, and macOS. Check the built-in game list first, because other titles need custom setup. For security coverage, stay on the main branch or latest release; older releases are unsupported. This is a local mod workflow, not a hosted service for a group.
Modrinth: Modrinth is a sensible starting point for Minecraft Java players who want one place to find content and manage modded instances. Its free platform is substantial, and creators get team controls, analytics, and monetization options. Hosting adds backups and server administration tools, with clear RAM and player ranges on the listed plans. The main cautions are the app's public-beta status, reported Linux stability problems, and hosting compatibility limits. Groups should confirm their loader, version, location, and expected player count before paying.
