RescueSlot Pro — Versioned Saves and Automatic Recovery

Your player should not lose progress because one JSON write broke.

RescueSlot Pro is a dependency-free Godot 4 addon for developers who want explicit save data plus the reliability work that usually gets postponed: rotating backups, recovery, schema migrations, profiles, and manual restore.

var result = RescueSlot.save_slot(     
"campaign",     
{"level": 12, "coins": 840},     
"player_1" ) 

Included

• Unlimited named profiles and slots
• One to ten rotating backups; three by default
• Automatic recovery from the newest valid backup
• Corrupt-primary quarantine and repair
• Backup inspection and manual restore
• Contiguous version-to-version schema migrations
• Strict JSON-safe validation before disk writes
• Structured results, recovery metadata, warnings, and signals
• Source code, demo, API reference, and commercial-use license

Explicit by design

RescueSlot does not reflect over scenes or serialize arbitrary Godot objects. You choose the dictionary you own, making save formats reviewable, testable, and easier to migrate.

Tested with Godot 4.6.3 and 4.7.1 on macOS. RescueSlot is not encryption, anti-cheat, cloud storage, or a zero-data-loss guarantee.
