# GUI Frameworks
|
||
|
||
AmigaOS spawned several GUI frameworks beyond the built-in GadTools/BOOPSI system. These frameworks provide layout management, user customization, and richer widget sets — features that the base Intuition API does not offer.
|
||
|
||
## Framework Index
|
||
|
||
| File | Framework | Era | Description |
|
||
|---|---|---|---|
|
||
| [mui/](mui/) | **MUI** (Magic User Interface) | 1993– | De-facto standard. Architecture, developer guide, code examples |
|
||
| *reaction.md* | **ReAction** / ClassAct | 1997– | Hyperion's official OS 3.5+ GUI toolkit |
|
||
| *bgui.md* | **BGUI** | 1994– | Lightweight BOOPSI-based layout system |
|
||
|
