What It Is

QML (Quest Markup Language) is a free, XML-based Choose-Your-Own-Adventure text adventure system. It organizes branching narratives around “sites” and “options,” making it suitable for interactive fiction and text adventures, while also being adaptable to non-story scenarios such as internal technical support workflows or simple casino-style games.

Core Capabilities

Based on the main documentation, QML supports state checks, random events, user input, numbers and strings, image maps, automatic redirects, if-else branching, and the insertion of images, sounds, and GIF animations. There are two ways to create content: writing simple text/XML directly, or using the free QML-Edit editor. Its main advantage is a low barrier to entry—authors do not necessarily need a programming background, making it well suited to content-focused creators.

Technology and Deployment

QML’s technology stack is very much of its era: on the client side, it depends on IE5+, VBScript, Microsoft.XMLDOM, and MSXML; on the server side, the documentation mentions that it can be made accessible from any browser via Apache or Windows Server, and may support text-to-speech clients or mobile phones. It is based on XML and DTD validation, giving it a clear structure, but compatibility with modern browsers, mobile platforms, and current security policies should be assessed carefully.

Pricing and Licensing

The documentation clearly states that QML-related content is free. Creators are free to do what they want with their own adventure works, including selling their story XML files; however, they may not sell the QML system itself, as it is in the public domain. The website does not mention commercial support, subscriptions, or paid services.

Pros, Cons, and Who It’s For

Its strengths are that it is free, has a simple format, supports branching and state logic, and comes with an editor plus tutorial documentation. Its drawbacks are its reliance on outdated IE/VBScript technology, as well as limited information on the modern ecosystem, APIs, SDKs, community, and maintenance. It is better suited to retro interactive fiction creation, teaching and research, maintaining historical projects, or developers who need to understand XML-based narrative formats. It is not suitable as a primary tool for modern web games or commercial content platforms.

Access from China

The documentation does not provide information about access from mainland China, payment, or CDN support, so this remains unknown. If you need a modern alternative, consider Twine, Ink, Ren'Py, or ChoiceScript, which generally have stronger community activity and better support for modern platforms.
