Kickstarter: Feathers UI for OpenFL and Haxe

Hey, everyone! A couple of months ago, I mentioned that I was working on a new OpenFL and Haxe version of my open source project, Feathers UI. I originally released these UI components for Flash/AIR about 7-8 years ago. Over that time, they’ve powered a ton of amazing creative projects, and the library has grown far beyond my initial expectations. Now, with the changing technology landscape, it’s time to give Feathers UI a new foundation. I think that Haxe and OpenFL are a perfect fit.

Today, I’m launching this new version of Feathers UI on Kickstarter so that the community can support its development.

Please help make Feathers UI for Haxe and OpenFL a reality by becoming a Kickstarter backer, Thank you!


This is great! I’ll certainly contribute in the next days.

I learned to be a developer with flash, creating Adobe Air projects. My first serious app was built using feathers for starling.

On the current days I’m developing for the web and when I have to do anything multiplatform I end up relying on react native or electron.

Being able to use a familiar stack that can export to native code in pretty much every platform is a dream. When it comes to performance, open FL + feathers UI will beat electron without a doubt and the developer experience will be more than acceptable, specially if feathers sdk gets ported as well.

Looking forward to it!

Thank you! I’m really happy with the performance so far, and I haven’t even fully optimized everything yet. Yesterday, I was playing around with a five-year-old Galaxy S5, and the ListBox component was scrolling smooth as butter. It was even good in a JS build (not just the native cpp target). I’ll be posting a link to an online demo soon so everyone can check out my progress.


I have a XOOM for real frail tests. :slight_smile: I wonder if it would scroll like butter.

This is really great that a mature UI framework could be destined for Haxe/OpenFL. For others, I have apps built with FeathersUI/SDK framework for Starling and it rocks, has a professional API and Josh’s documentation of the Starling version is top notch.

It was only the last couple weeks I realized how cool this could actually be, complex UI is complex and having a deep 2D UI framework is a good thing. I say this since I am sure I am not the only one that wanted to migrate away from AIR/AS3 but had no really good 2D UI framework, this is it (from my experience).

This project also gives me the chance to try and contribute to Haxe/OpenFL ecosystem down the road.

This is one of the things I’m looking forward to with Feathers UI for OpenFL: Some well set standards to make it easy for a community/ecosystem to prosper. I envision Feathers UI marketed as an alternative to other cross-platform engines with UI components such as Flutter. With the advantage to be able to publish to even more targets. Its amazing to be able to easily test in a smartphone with several build types (JS, Air, Native…).


I think my oldest device is a Nexus One phone from 2010. I should give that a try! It’s stuck on Android 2, though. I’m not sure if OpenFL can target devices that old.

I also have a Nexus S from 2011. That one is running Android 4.x, so it would be more likely to work.

I’ll charge them up and see what happens!

I have a Nexus 7 2nd gen from 2013 and a Pixel 2, iPhone and IPad Air 1st.

I said the XOOM because I was able to run most of the Feathers apps I have made on the XOOM, slower but runs. (my UIs are pretty busy so it surprised me)

Is it possible to receive an invoice if I back you on Ks?

I can certainly create an invoice and email it to you after Kickstarter has processed your payment. I will mark it as “paid in full” for the amount that you pledged. Will that work for you?
