Welcome to the MUI for AmigaOS Development Site

This web page is a public site for organizing and maintaining the development of the so-called Magic User Interface (MUI) for AmigaOS-driven computer systems. While the services and information on these pages are mainly focused for the developers of the AmigaOS port of MUI only, it also provides online API documentation targeted for interested software developers using MUI. In addition, for end-users wanting to enhance their MUI experience, this site provides updates as well as online documentation and Frequently Asked Questions (FAQ). Even more important every developer and end-user using MUI is invited to report bugs and request enhancements by using the public ticket management system.

What is MUI?

MUI is the abbreviation of Magic User Interface, an object-oriented BOOPSI-driven user interface framework for AmigaOS-based operating systems. It features a flexible user interface where end-users can define the Look&Feel of applications using MUI in high detail. Beside this end-user flexibility MUI comes with a wide variety of so-called Custom Classes which developers using MUI can use in their applications and which provide additional functionality (e.g. such as a full-fledged text editor). This third-party custom class functionality as well as the high user flexibility in defining the Look&Feel of a MUI applications makes MUI the most advanced user interface framework for AmigaOS computer systems today.

Getting MUI

The MUI versions available at this web site are developed and distributed with official permission by the original MUI author, Stefan Stuntz. These versions are distributed under a shareware license and provide limited functionality regarding the possibility to tune all user interface settings. Aside with this limited functionality the versions distributed here come with a default Look&Feel while the full functionality can be unlocked by registering (via PayPal) and receiving a key file from the original authors' homepage (

Finding help

These web pages should serve as a starting point for MUI application developers as well as for end-users in finding information, documentation as well as FAQs. As such, the API documentation of MUI as well as the general documentation are about to be converted to editable pages on this web site.


While development on MUI itself is limited (due to its closed-source license) to a closed community of developers, interested parties can still contribute in a wide range to the development and future success of MUI. One possibility would be to contribute in translating YAM to your own language as an official translator. Another way would be to help to maintain the online user as well as the API documentation or the FAQs pages. And last not least you can also perfectly contribute in identifying bugs or potential enhancements you can file to us via the ticket management system of this site. We would really be happy to receive your help.
