About Fallout Shelter Save Editor

Free, open-source tool for editing your Fallout Shelter vault saves

📖 Our Mission

Fallout Shelter Save Editor is a free, open-source web application for inspecting and editing supported Fallout Shelter vault save fields. The project is designed to keep the editing step in the browser while making the file-access, backup, and compatibility limits clear to users.

We believe that single-player games should be enjoyed however players want. Whether you're looking to experiment with different vault strategies, recover from a difficult situation, or simply have fun with unlimited resources, our save editor makes it possible.

🔧 What We Offer

  • Browser-Based: No separate save-editor installation is required. The editor interface runs in your browser using JavaScript. Try our online save editor now.
  • Browser-Based Editing: The editor processes the selected save in the browser. Keep the file on a trusted device and review our Privacy Policy for analytics and advertising services.
  • Platform Workflows: The site documents PC, Steam, Android, and iOS file-access workflows. File locations, cloud behavior, and compatibility can vary by device and game version; check the platform guides first.
  • Open Source: Our code is publicly available on GitHub for transparency and community contributions.
  • No Account Required: The editor flow does not require a subscription or account. Site analytics and advertising disclosures are listed in the Privacy Policy.
  • Repository-Based Updates: Check the linked source repository and issue tracker for implementation changes; no page can promise compatibility with every future save format.
  • Advanced Tools: Need manual editing? Use our save decryption tool for JSON access.

👥 Our Team

This project is maintained by passionate developers and Fallout Shelter fans. Originally created by MobileSam, the editor has been updated and improved by rakion99, TheCreatorJames, and numerous community contributors.

We're a community-driven project that welcomes contributions, bug reports, and feature suggestions from users worldwide.

🛡️ Safety & Security

Your security is our top priority:

  • The editor flow processes the selected save in your browser without an application upload step
  • Save-file handling is separate from site analytics and advertising services described in the Privacy Policy
  • Open-source code allows anyone to verify our security claims
  • Analytics and advertising disclosures are maintained on the Privacy Policy page
  • Users should review source changes and keep backups before editing
