SaveGuard browser save editor

Edit game saves safely in the browser without downloading sketchy exe files

Problem

Players want to edit saves for RPG Maker and similar games, but forum editors are mostly exe files, Windows-only, and scary to download. Mac, Linux, and Android users have no good local options. Many tools also upload saves to a server, creating privacy risk.

Solution

A pure web save editor that parses and rebuilds files locally in the browser, with no uploads and no signup. Start with RPG Maker MZ .rmmzsave, validate and add fields like stats, items, and variables, then expand to .rpgsave and earlier formats.

Users

Players of RPG Maker and indie games, casual users who won't download exe files, Mac/Linux/mobile players

MVP

Drag in .rmmzsave and parse in-browser; view and edit core fields like gold/money; export the new save; keep selected files in local storage without server uploads; a page listing supported formats and verified fields

Revenue

Free basic features with paid advanced field unlocks or batch processing; affiliate ads; one-time purchase ad-free version

Why now

RPG Maker and similar engines power a long tail of indie games, and in-browser local file handling makes it possible for an indie to start with one or two formats
