The first version of Vorple was as a library for Undum, and allowed the inclusion of many features to Undum stories, such as buttons, images, sound, etc. It was released in November 2011.
In 2015, librairies for Inform 6 were written by Hugo Labrande, allowing the compilation of Inform 6 games for Vorple; the release was announced on November 17th 2015. The game Tipelau, released a few weeks later, is the first to have been released using these librairies.
The Vorple interpreter for Inform allows the author to use the following tools in games:
- Multimedia, including sounds, images, and Youtube videos;
- Hyperlinks (to a website or a command);
- Text effects, including different fonts, font sizes and alignment;
- Tooltips on mouse hover, or displaying by themselves;
- In-browser notifications;
The Vorple for Inform interpreter being based on Parchment, it only supports Z-Machine games. This currently poses a problem for Inform 7 stories, as the newer versions of I7 generate code that is too big to fit in a Z-Machine format ; as such, Inform 7 has been effectively incompatible with Vorple for a number of years. However, this does not pose a problem for Inform 6 games, what with recent compatibility added.
