Decker
A downloadable tool for Windows, macOS, and Linux
Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior. It draws strong influence from HyperCard, as well as more modern "no-code" or "low-code" creative tools like Twine and Bitsy.

Combine drawings and photographs with behaviors:

Build games and toys,
And even useful applications!

Decker can be used for making:
- Interactive Documentation
- E-Zines
- Visual novels

- Point-and-click games
- And much more!
