What Fallout Shelter Save Editor is
Fallout Shelter Save Editor is a free browser app for viewing and changing Fallout Shelter save files. It processes saves locally: the browser decrypts, edits, and re-encrypts them, and files are not uploaded to a server. You can adjust dwellers’ SPECIAL stats, levels, happiness, health, equipment, and appearance, or revive dead dwellers. Vault editing covers caps, resources, food, water, power, Nuka-Cola, and lunchboxes. Room tools let you rearrange, upgrade, theme, clear rocks from, and repair rooms. The editor can display reward tracks for every season, including past ones, and claim missed rewards. It also shows a vault family tree with relationship and genetics statistics, includes catalogs of weapons, outfits, pets, junk items, and recipes, and offers a save-health check to help repair corrupted files. It supports saves from PC, Android, iOS, and Switch. Before the first export, it downloads a timestamped backup of the original file. The project says it has no backend or telemetry and is an independent, non-commercial fan project for personal and educational use.

The full review of Fallout Shelter Save Editor
Fallout Shelter Save Editor is a browser-based tool for inspecting and changing Fallout Shelter saves. It is best suited to players who want precise control over dwellers, vault resources, or past season rewards. Its broad editing toolkit is compelling, provided you are comfortable changing a game save rather than relying on ordinary in-game progression.
Overview
The app decrypts, edits, and re-encrypts saves in the browser, without uploading them to a server. The project says it has no backend or telemetry, and it automatically downloads a timestamped copy of the original file before the first export. Local processing and that recovery copy are meaningful safeguards, although neither changes the fact that save editing itself can alter your progress.
The editor runs on the web and supports saves from PC, Android, iOS, and Switch. It is an independent, non-commercial fan project, free for personal and educational use; its original source code is MIT-licensed. 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, as well as reviving dead dwellers. Vault controls reach caps, resources, food, water, power, Nuka-Cola, and lunchboxes. That range suits both focused character adjustments and larger changes to a vault's stock and progression. It is less suitable for players who only want to view a save or preserve the game's usual progression.
Room management lets users rearrange and upgrade rooms, change their themes, clear rocks, and make repairs. The season-pass section displays complete reward tracks for every season, including past seasons, and can claim missed rewards. Together, these tools make the editor useful beyond basic resource changes, especially for players looking to revisit vault layout or seasonal rewards.
A family-tree view adds relationship and genetics statistics that the game does not show. Catalogs cover weapons, outfits, pets, junk items, and recipes, while a save-health check can help repair corrupted saves. These inspection and repair tools broaden its appeal, though the app remains focused on Fallout Shelter rather than general save editing.
Pricing
The Free plan costs nothing. It is browser-based, requires no account, carries no ads or telemetry, and is MIT open source. Every described editor feature is included without a paid tier, so there is no cheaper plan with reduced editing scope to weigh against a subscription. The project is provided free for personal and educational use.
Platforms
The editor itself is web-based, with support for saves from PC (Windows), Android, iOS, and Switch. Those are supported save sources, not separate native editor apps; choose it if a browser workflow fits your device, rather than expecting a standalone Switch app.
Who it's for
This is a strong fit for Fallout Shelter players who want to adjust dweller attributes, manage vault resources and rooms, claim past season rewards, or inspect family relationships. The local processing and automatic original-file backup are useful for anyone making consequential changes. Players who want an official publisher-supported tool, or prefer to advance only through normal gameplay, should look elsewhere.
Pros and cons
- Pros: Local browser processing, no backend or telemetry, and an automatic timestamped original-file backup give users privacy and a recovery copy before the first export.
- Pros: Dweller, vault, room, season, family-tree, catalog, and save-repair features cover much more than basic inventory editing.
- Pros: The free plan includes the browser editor without accounts or ads.
- Cons: It is an independent fan project, not an affiliated or endorsed Bethesda, ZeniMax, or Microsoft product.
- Cons: The editor is web-based, so it is not a native app for the supported PC, mobile, or Switch platforms.
- Cons: Its broad powers are a poor fit for players who want to leave character and vault progress untouched.
