What it is
This free, open-source browser application lets you inspect and modify Fallout Shelter save files. Its tools cover dwellers, vault resources, rooms, quests, items, and seasons, and it also shows family-tree details. Files stay in the browser, with a timestamped backup downloaded before the first export. Nothing needs installing, but JavaScript is required, and edits can damage saves or conflict with game terms.

Who it suits
Fallout Shelter players working on vaults from supported platforms Players seeking browser-local processing and automatic backups Technical users interested in advanced JSON and self-hosting
Choose this if you want detailed control over one Fallout Shelter vault across PC, mobile, and Switch saves. It combines everyday edits with quest, season, family-tree display, catalog, and advanced JSON tools, while keeping processing in the browser. The free offering removes cost and account setup. Preserve the downloaded original, review diagnostics and diffs, then export carefully. Players who need another game, a native install, or a documented API should look elsewhere.
The full write-up
Overview Fallout Shelter Save Editor is a free browser app for viewing and changing Fallout Shelter saves. It is best suited to players who want precise control over dwellers, vault resources, and progression. Its broad editing range and local processing make it a capable choice for deliberate save changes, though it is not an official Bethesda tool. The app decrypts, edits, and re-encrypts saves in the browser; files are not uploaded to a server. The project says it has no backend or telemetry, and a timestamped copy of the original file downloads automatically before the first export. That backup is a practical safeguard, but editing still means departing from the game’s ordinary progression. The browser app works with saves from PC, Android, iOS, and Switch. It is an independent, non-commercial fan project, free for personal and educational use under the MIT license for its original source code. It is not affiliated with, endorsed by, or sponsored by Bethesda, ZeniMax, or Microsoft. Key features Dweller editing covers SPECIAL stats, levels, happiness, health, equipment, and appearance, and can revive dead dwellers. Vault controls reach caps, resources, food, water, power, Nuka-Cola, and lunchboxes. This is useful both for narrow fixes to a character and for broader changes to vault progression; players who only want a save viewer may find the editing scope unnecessary. Room management lets players rearrange, upgrade, theme, clear rocks from, and repair rooms. The editor also displays complete season reward tracks, including past seasons, and can claim missed rewards. Together, these tools make it relevant to players looking to revisit vault layout or rewards as well as character and resource values. A vault family tree adds relationship and genetics statistics the game does not show. Catalogs cover weapons, outfits, pets, junk items, and recipes, while a save-health check can help repair corrupted files. The combination of inspection and repair tools broadens the app beyond direct progression editing. Pricing The Free plan costs nothing and includes the browser-based editor with no accounts, ads, or telemetry. There are no paid plans or account-based seat limits to weigh against the feature set. For a free, single-purpose tool, the trade-off is not a tier cap but that its focus is Fallout Shelter save editing and it is provided as a non-commercial fan project for personal and educational use. Platforms The editor runs on the web, with supported save files from PC (Windows), Android, iOS, and Switch. That split is useful for players moving between supported platforms: the app is browser-based rather than a native desktop editor, while the save itself can come from any of those four systems. Who it's for Choose it if you want to edit Fallout Shelter dwellers, vault resources, rooms, or season rewards, inspect family relationships, or try to repair a save. Local processing and an automatic original-file copy are meaningful safeguards for players making changes to valuable progress. Look elsewhere if you want an officially supported Bethesda product or a general-purpose editor for other games. Pros and cons Pros: Broad controls span dweller attributes, vault resources, rooms, and missed season rewards, so players can address more than one kind of save change in one tool. Pros: Saves are processed locally, with no backend or telemetry, and the original file is backed up before the first export. Pros: Family-tree statistics, item catalogs, and save-health checks add inspection and repair value beyond editing. Cons: It is a fan project, not an official Bethesda, ZeniMax, or Microsoft product. Cons: It is specifically for Fallout Shelter; players seeking a save editor for another game need a different tool. Alternatives For other options, browse Game save editors . Palworld Save Pal is the better fit for Palworld players: it is free across Android, iOS, Linux, macOS, web, and Windows, with every feature and no paywall. SaveEditor.top suits someone looking for a broader save-editor option; its free plan allows files up to 50MB, requires no registration, and supports only certain formats. Pokémon SRM Editor is aimed at Pokémon Red, Blue, and Yellow saves, with a web app and desktop app. NHSE is a free desktop option for its supported game, but it requires an existing save and does not dump or import save data from the console. NMSE (No Man's Save Editor) is a free, ad-free desktop save editor. Elden Ring SaveForge is a free Windows option. ACNH Save Editor is another free option. Kingdom Save Editor is free and open-source for Windows. Verdict Fallout Shelter Save Editor is the right pick for players who want detailed control of a Fallout Shelter vault without uploading their save, especially when family-tree inspection, missed rewards, or save repair matter. Its main reason to look elsewhere is equally clear: it is an unofficial fan project limited to this game, not a supported or general-purpose editor.
