What Circinus Mod Manager is

Circinus Mod Manager is a free desktop application for arranging RimWorld mods before starting the game. Its HALO system places mods into eight phases according to their contents and explains each placement. You can add your own sorting rules; when rules conflict, the manager identifies the conflict so you can remove one and finish sorting. Before launch, it checks for missing dependencies, declared incompatibilities, misplaced definitions, duplicate mods, and texture collisions. Imports include ModsConfig.xml files, save files, Steam collection links, RimSort exports, rentry pages, and clipboard contents. Workshop downloads run through SteamCMD in a queue that can pause when Steam slows down, retry failures, and resume after the app closes. Sorting and checks can use files already stored locally, while community databases remain disabled unless enabled. Circinus runs on Windows, Apple Silicon Macs, and 64-bit Linux through an AppImage. It checks updates at startup, verifies signatures, and shows SHA-256 fingerprints for downloads. The project is independent and unaffiliated with Ludeon Studios.
