NMSE (No Man’s Save Editor) is a free, open-source desktop tool for editing No Man’s Sky saves. It can change inventories, unlock items, adjust discoveries, and create backups. Its visual inventory grid supports drag-and-drop item management, auto-stacking, and sorting, and a backup picker can restore saved copies. The editor supports saves from Steam, GOG, Xbox Game Pass, PlayStation 4, and Nintendo Switch, as well as all 16 game languages. It also supports cross-editor import and export of practically everything. NMSE runs on Windows, Linux, and macOS: Windows users receive a ZIP release, Linux has an AppImage with Wine included, and macOS has a DMG with a Wine launcher. The Linux and macOS versions run through Wine compatibility layers. The maker says NMSE will remain free and ad-free. It is a fan-made GPL 3.0 project and is not affiliated with Hello Games; the maker points users to Discord for community help and GitHub issues for bug reports.
