There are several Inform 7 extensions (and other design systems) that perform the same task, but this one is the only (AFAIK) based on the Glulx VM.
The “MilleUna Framework” is a collection of Inform 7 extensions devoted to the creation of online Interactive Fiction. Authors may use hyperlinks, HTML tags and JavaScript code in Inform 7 texts, and their games are executed by the Quixe interpreter in a browser.
To understand what I mean, a simple online example is available here: youdev.it/if
Initially the framework was written to support italian authors, but now all the necessary extensions are also available in English.
