RimSort

RimSort is a free, open-source, multi-platform mod manager built specifically for RimWorld, designed to help players organize and maintain large mod collections without relying on in-game ordering alone. It focuses on reliability and community-driven maintenance, positioning itself as an alternative to other external RimWorld mod managers while keeping the workflow straightforward for everyday use. The app is intended to be used before launching the game so you can curate your active list, resolve ordering concerns, and reduce the risk of startup errors caused by messy load orders. Because it targets Windows, macOS, and Linux, it is meant to fit neatly into typical Steam-based RimWorld setups regardless of operating system. RimSort also emphasizes a practical onboarding path through downloadable releases and documentation, so users can install it quickly and then refine their setup over time.
