Trillium Solutions operates the Trillium Solutions Archive, a community platform for browsing and downloading archived Minecraft modifications and related tools. The site lists Minecraft mods, clients, plugins, macros, source files, and other resources, with filters for game versions, mod loaders, categories, and download activity. Visitors can sort listings by ratings, date, or popularity, and view details such as authors, compatibility, verification status, usage instructions, and community feedback.

The archive includes resources for Minecraft versions ranging from older releases to recent versions, with many entries designed for Fabric. Listings cover both free and paid downloads, and the site highlights community activity through upload, download, membership, and online-user counts. Users can browse the archive, search for specific items, and access instructions for installing some files, typically by placing them in the game’s mods folder. The platform also provides account sign-in, including Discord sign-in, and links to information about how the archive works, sponsorship, donations, terms, privacy, and its Discord and GitHub communities. Its stated tagline is “Everything is just free.”.
