You can now get Bindables as part of the Flexalon + Proxima + Bindables bundle.

Bindables brings the power of reactive programming to Unity—giving you a clean, declarative way to track game state and automatically reflect changes wherever they’re needed.

With Bindables, you declare your state using Bindable<T>, then declaratively bind that state to any Unity component—like UI text, images, animations, or prefabs. It works seamlessly across UGUI, UI Toolkit, and any other Unity objects.

Reactive by Design: State changes drive everything. You declare your bindings once and they update automatically.

Extension Methods: Bindables generates Bind extension methods to every Unity object (that you want). This makes easy and type-safe to bind to all built-in Unity types, 3rd party packages, and your own components. Materials, images, text, sprites, transforms, you name it.

UI Toolkit and uGUI Support: Works with both UI frameworks in the same way. Declare bindable state and bind it to UI components.

Two-Way Bindings: For input fields, sliders, dropdowns, and toggles, you can bind your state to update automatically on user input.

Advanced Bindings: Derived state, animations, time intervals, file URIs, and more.

FEATURES:

Bindable: declare reactive state.
Exension Methods: All Unity components get convenient new .Bind*() methods.

For example: textmeshpro.BindText(playerName)

Derived: transform or combine Bindables into new state.
BindableList: Bind to lists to instantiate prefabs or visual elements.
BindableDictionary: Bind to dictionaries to instantiate prefabs or visual elements.
BindableAnimator: Drive animations using easing curves, math, or Unity animation curves.
Bind to input actions, events, time intervals.
Bind to file and web URIs to download images and audio clips.
Automated event handler management with BindContext.
