FeliX is a save file visualizer for the game Satisfactory. It is written in TypeScript and JavaScript using Vue.js and three.js.

You can upload your .sav files directly in the browser or download the desktop app created using Electron. FeliX also has some basic editing capabilities. It can convert the .sav format to a human-readable .json format. You can edit the .json file externally and then open it in FeliX to convert it back to a .sav file. FICSIT - FeliX Screenshot
