HaxeUI review
A free, open-source Haxe UI framework with rendering options across multiple backends.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HaxeUI is a free, open-source user-interface framework for developers building desktop, web, or mobile applications with Haxe. Its central idea is to keep interface logic in a shared core while a chosen backend handles rendering and platform-specific behavior. Teams can define interfaces in Haxe code or XML, then compose them from reusable components, containers, and layouts. That makes it a fit for Haxe teams that want to share UI work across targets without committing every project to one rendering system.
The backend ecosystem is the main reason to consider HaxeUI. It connects with Kha, Luxe, NME, OpenFL, hxWidgets, Raylib, Heaps, PDCurses, and Flixel. The shared interface code can be paired with different backends, and some backends provide native OS components while others use framework-specific rendering. CSS-style syntax supports skinning, and list and table virtualization address larger collections of interface items. This separation offers flexibility, but it also makes the backend an important architectural choice: rendering and platform behavior vary with the option selected. Teams should check that a backend fits their target platforms and desired control style before settling on it.
HaxeUI has no paid tier in its stated free pricing model, and its deployment is self-hosted. Its targets span Windows, macOS, Linux, iOS, Android, and web, though desktop OS support depends on the backend. Community support is the listed support channel, so teams seeking a formal vendor support path may prefer another framework. Choose HaxeUI when Haxe, shared interface code, and backend choice matter more than a uniform rendering approach. It is less suitable when a project needs predictable OS support independent of backend selection or relies on vendor-provided support.
