What RepoDitor is

RepoDitor is a free, open-source editor for local R.E.P.O. encrypted .es3 save data. The unofficial Electron desktop app runs separately from the game and needs no mod loader or installation in the game directory. Its workspaces cover run overviews, player health, upgrades, supported run values, items, maps and cosmetics. Item changes are limited to eligible exact-instance refill-to-full actions, and maps can be listed but not edited. Before saving, RepoDitor checks the source fingerprint and whether the game is closed, creates a timestamped backup, validates the encrypted output and replaces the source atomically. Save parsing and editing run locally; the renderer cannot access raw decrypted save JSON. The desktop version requires Windows x64 and a local R.E.P.O. installation and save. A browser version allows manual file import and export, but does not provide every desktop capability. Desktop downloads are available through GitHub Releases, Nexus Mods and Thunderstore, with GitHub Releases as the canonical source. The project uses the MIT License, and desktop updates are manual.
