RescueSlot Lite — Reliable Saves for Godot 4

RescueSlot Lite is a dependency-free GDScript plugin for creating explicit, versioned JSON save files in Godot 4.

It provides a straightforward save system for solo developers and small teams who want structured results, data validation, and safer file writes without building everything from scratch.

PRO VERSION: https://shell-code.itch.io/rescueslot-pro

Lite features

• Save and load JSON-compatible dictionaries
• One default profile and save slot
• Explicit schema versioning
• Recursive data validation
• Crash-resistant temporary-file writes
• Structured success and error results
• Simple global RescueSlot API
• No servers, accounts, APIs, or runtime dependencies
• MIT licensed

Supported data

RescueSlot accepts:

• Dictionaries with string keys
• Arrays
• Strings
• Integers and finite floating-point numbers
• Booleans
• null
• Nested combinations of these values

Godot objects, resources, vectors, colors, callables, packed arrays, non-string dictionary keys, and non-finite numbers are rejected.

JSON does not preserve custom Godot types or guarantee exact large-integer representation.

Tested versions

• Godot 4.6.3
• Godot 4.7.1

The plugin is written entirely in GDScript and has no third-party runtime dependencies.

Lite limitations

RescueSlot Lite supports only the default profile and default slot. It does not include rotating backups, automatic corruption recovery, schema migrations, or backup inspection.

RescueSlot Pro adds:

• Multiple profiles and slots
• Configurable rotating backups
• Automatic corrupted-file recovery
• Sequential schema migrations
• Backup inspection and restoration

Upgrading only requires replacing the addons/rescue_slot directory. Existing Lite save files remain compatible.

Important scope

RescueSlot is intended for small save files outside latency-sensitive gameplay.

It is not encryption, anti-cheat protection, cloud storage, arbitrary object serialization, or a guarantee against every possible form of data loss.
