SaveKit – Lightweight Save/Load Solution for Unity

Solo Save Kit is a modern, lightweight save system for Unity that makes saving and loading data simple, secure, and powerful. Designed for both beginners and experienced developers, it gives you everything you need to persist player progress, settings, and game state across all major platforms.

With just two lines of code — or no code at all using the AutoSave components — you can start saving instantly. Data is serialized with industry-standard JSON, with optional AES encryption, GZip compression, and automatic backups for reliability. Multiple save slots are supported out of the box, letting you manage profiles with ease.

The included Save Explorer window sets Solo Save Kit apart. Inspect your saves directly inside Unity, view size and timestamps, decode encrypted or compressed files, search and syntax-highlight JSON, export to CSV, and manage slots or keys with bulk actions. Debugging and testing saves has never been easier.

Whether you’re building for desktop, mobile, or WebGL, Solo Save Kit offers a clean, dependency-free runtime that “just works” while giving you professional-grade tools in the editor.
