Persistent Asset is an easy-to-use, reliable, and complete save system with a unique concept: it saves your data in scriptable objects.
Fast and Easy to Use
Persistent Asset does not require any extra setup.
Create a class with the fields you want to save, and you are good to go!
The tool even provides a way to save and load without any actions or configuration needed from you.
Clean and Maintainable Workflow
The scripts follow SOLID principles and are separated into logic modules with one-way dependencies.
This makes common operations like changing how some data is saved during development as simple as a few clicks in the inspector.
Integrated Design
Persistent Asset is highly integrated with Unity’s default behavior, ensuring ease of use and future-proof functionality.
It makes full use of modern engine features to be both comprehensive and straightforward.
Extendable API
Want to use a non-Unity serialization logic, like one from another tool on the store?
Or enjoy the simplicity of Persistent Asset with another save behavior, whether offline or online?
By inheriting from dedicated classes, you can extend the tool’s functionalities and make it compatible with any other serialization or save system.
Some utility classes are provided, making the process simpler.
Standard Features
• Automatic save and load at specific application events
• Automatic regular background save
• Save in local files, PlayerPrefs, or custom sources
• Backup your data in case of a crash, in the editor and at runtime
• AES encryption and secured hash generation
• Compression using Gzip
• And more!
Unique Features
• Effortlessly manage multiple save slots
• Reset to default values at runtime
• Synchronous and asynchronous support
• Memory dump protection for the encryption key
• Composition-based approach; no inheritance issues
• And more!
Painless Usage
The tool includes debug utilities: extensive logs in the inspector (no console spam!), benchmarking save and load operations, and a dedicated test component.
It does not produce any script warnings and works just the same in no reload on play mode.
The entire public API has XML comments, regrouped in a DocFX generated PDF for easy access, and all sources are included (100+ scripts).
Documentation and Help
The documentation is clear, complete, and includes a one-page quick usage guide.
The demo showcases all features in a complete game scenario.
Contacting support via email guarantees a response within a day or less, and there is a public Discord community for additional assistance.

Changelogs
VERSION 1.1.0: Serializer Module Update (09/20/23)
Aim of this update is to let you handle custom serialization logic by creating a small class instead of redefining an entire PersistenceManager.
New classes
• Serializer can be inherited to define a serialization logic
• VariableSerializerPersistenceManager is a PersistenceManager that contains a Serializer
• UnityJsonSerializer is the default Serializer, it follows Unity serialization rules
Other change
• SerializationMode enum created, used for Serializer methods
• DemoSecureKeyInitializer now only logs when launching the game from the editor
• Renamed the SerializeToString and DeserializeFromString methods in PersistenceManager to GenerateDefaultValues and ResetToDefaultValues
• Prototype, PlayerPrefs, and File persistence managers now inherit from VariableSerializerPersistenceManager
• PersistentJsonUtility.FromJsonOverwrite now has a parameter letting you choose whether to merge arrays or override them
• Addons editor classes updated to account for the aforementioned changes
