CubeDI

CubeDI is a modern dependency injection (IoC) container for Unity, built to be small, fast and genuinely easy to use.

Why CubeDI?

Dependency injection shouldn't require a 300-page manual or a heavyweight framework. Zenject is powerful but bloated; VContainer is lean but under-documented. CubeDI hits the sweet spot: a tiny, readable API you can learn in an afternoon, backed by a resolver that stays out of your way at runtime.

Built for real projects

- One clear entry point: SceneContext per scene, GlobalContext auto-loaded across scenes (no bootstrap scene needed).

- Constructor, method, field and property injection - use whichever fits.

- Real keyed (tagged) bindings, multi-binding, and nested child containers.

- A clean lifecycle: Initialize, Tick / FixedTick / LateTick, and deterministic Dispose.

- Prefab instantiation with dependencies injected before Awake.

- Zero-allocation injection at runtime - no GC hitches during gameplay.

- No hidden global state - safe with disabled Domain Reload and fast Play Mode enter.

- IL2CPP / AOT friendly. No code generation required to ship.

See it, don't guess it

CubeDI ships with a live Dependency Graph window (Window > CubeDI > Dependency Graph): inspect every context and binding, and catch missing dependencies and constructor cycles before they ever throw at runtime. Nothing like it comes built into Zenject or VContainer.

Everything is plain C#, fully commented, and shipped with complete source code - no DLLs, no black boxes. Read it, tweak it, own it.

Roadmap

- Optional source generator for zero-reflection injection on AOT platforms.
