Stratum
A powerful, modern mod manager for Bethesda games — deeply integrated with Modding Lounge.
Inspired by Mod Organizer 2. Built from scratch in Rust + React for speed, safety, and a seamless modlist experience.
Non-Destructive By Design
Mods are deployed via symlinks — your game files are never modified. Remove or reorder mods instantly without reinstalling anything.
Wabbajack-Inspired Compilation
Author and share full modlist compilations using hash-based archive indexing. Binary diffs for modified files — no file bundling, fully legal.
Built for Performance
Rust-powered backend via Tauri 2. Handles conflict detection across hundreds of mods instantly, with a virtualized UI that never lags.
