WagSave - Save Game System

Full SDK. No-code editor. Zero lock-in.

Whether you're writing every line or skipping code entirely, WagSave gives you the tools to build your save system exactly how you want it.

WagSave is a comprehensive, production-ready save game system for Unity 2022 LTS and above, designed to serve developers of all experience levels — from students building their first game to professional studio teams shipping on multiple platforms. It provides a flexible, extensible architecture for saving and loading game data across a wide range of output formats, platforms, and optimization strategies, all configurable through a robust Unity Editor toolset.

OUTPUT FORMATS

Binary

Compact and fast. Ideal for production builds where file size and read speed matter.

JSON

Human-readable and portable. Great for debugging and cross-platform development.

Text

Plain text output for simple or legacy save structures.

PlayerPrefs

Unity's built-in key-value store for lightweight settings and small save data.

Cloud Save

Sync saves to Unity's hosted cloud backend. Requires Unity Gaming Services (optional dependency).

Note: Binary, JSON, and Text formats each include an indexed variant that uses a data map for random access, allowing individual values to be read without loading the entire file into memory — ideal for larger save files.

SAVE OPTIMIZATION

Compression

Reduce on-disk file size automatically.

Encryption

Protect save data from user tampering.

File signing

Detect corruption or unauthorized modification.

Indexed files

Uses a data map for random access so individual values can be read without loading the entire file into memory, keeping performance smooth with larger save files.

FEATURES

Save Slot System

Full multi-slot support so players can maintain multiple independent save states. Includes a ready-to-use base UI for save and load slot selection, fully customizable to match your game's visual style.

Autosave

Built-in autosave system with interval-based and event-driven trigger options, configurable directly in the Unity Editor.

Unity Editor Toolset

A comprehensive Editor integration for configuring all save options, formats, optimization layers, and slot settings. Includes per-profile setup, a debug view to inspect save state and serializer output, and extensive logging to trace the complete save and load flow.

Extensible Architecture

Advanced developers can create entirely new output formats or override existing ones. Custom serializers can also be created or replaced to take full control of how save data is structured and encoded — no package source edits required.
