Satisfactory Map Editor - Best Save Tools
Drop a .sav file and see your whole factory: buildings, belts, resource nodes, vehicles and collectables. Two browser tools do this now - here is how they differ.
Free toolsNo installBrowser + desktop.sav files
The community favorite is SCIM (satisfactory-calculator.com interactive map). A new open-source editor, satisfactorymap.net, parses saves locally in Rust-compiled WebAssembly and claims ~13x faster loads on huge saves - a 600k-object factory in about 8 seconds.
SCIM (satisfactory-calculator)
- Interactive map + save editor - upload a save, view the factory, spawn and edit buildings
- Resource overlays - nodes by purity, slugs, artifacts, drop pods, caves
- Part of a bigger toolkit - production planner, recipes, power math
satisfactorymap.net (new)
- Runs fully local - the .sav is parsed in your browser, nothing uploads
- Search everything - find items across all inventories ("where are my hard drives?")
- Edit + download - move, copy/paste, rotate, delete with undo
- Desktop app for saves too large for a browser tab
FAQ
Is it safe to edit my save?
Both tools write a new .sav - keep a backup of the original before loading an edited file.
Which should I use?
Small saves: either. Huge endgame factories: the WASM editor is dramatically faster; SCIM has the fuller feature set and production planner.
