OpenUPM¶
🔹 What it is:

- Hosts open-source Unity packages, allowing you to install and update them easily within Unity’s package system.
🔹 Pros:
✅ Fully compatible with Unity’s Package Manager.
✅ Provides Unity-specific libraries, tools, and plugins (e.g., Odin Serializer, Addressables extensions).
✅ No external tooling required—integrates directly into Unity workflows.
✅ Supports scoped registries, making it easy to manage multiple package sources.
🔹 Cons:
❌ Smaller library selection compared to NuGet (mostly Unity-related packages).
❌ Some packages might not be actively maintained.
