JustSave | Zero-Code Save System

JustSave — Zero-Code Save System You don't manage every actor individually. Everything is just a checkbox.

No serialization code. No per-actor wiring. No save manager to build. Add the Saveable component, tick what you want to keep — centrally in the JustSave panel, or with the standard SaveGame flag — and call Save. Your whole world persists. That's the entire workflow.

JustSave is a zero-boilerplate save/load framework for Unreal Engine 5. The design goal is simplicity: instead of writing and maintaining custom save logic for every class, you describe what to keep with a checkbox and let JustSave handle how through reflection. It works identically in Blueprint and C++, and — critically — it works in packaged builds, not just the editor.

Add the Saveable component to an actor and it shows up in the JustSave panel automatically. From there, choosing what persists is just ticking boxes — never writing serialization code — and there are two equally valid ways to do it:

Centralised, in the JustSave panel (the easy route). The Configuration window lists every saveable class and all of its properties in one place; tick the ones to keep. No per-actor editing, no flags to remember — one visual source of truth for everything your game saves, and you can see and toggle properties you'd never expose as SaveGame by hand.

Per-property, the classic Unreal way. Or mark a property with the standard SaveGame flag right on the actor or Blueprint, exactly as you already do — JustSave picks it up automatically.

Both routes do the same thing (the effective saved set is the union of the two), so mix and match freely. Then call Save and your whole world persists — actor state, spawned and destroyed actors, references between them, and cross-level data — identically in Blueprint and C++.

A save system is only worth what it does the day you ship. JustSave is fully documented (a bundled User Guide and Technical Reference, plus an in-editor quick-reference Guide), works in packaged builds (config cooks into your game via DefaultGame.ini — verified on packaged Win64), and is self-contained — no separate example project to download before you can use it. It covers the features you expect from a premium save plugin — open-world support, server-authoritative multiplayer saves, slots, thumbnails, and compression — and adds an integrity pipeline (AES-256 anti-tamper, CRC32, atomic writes, auto-backup, live save-version migration) and a visual Save Graph on top. Simplicity is the headline; the depth below is the payoff.
