HTML First
HTML First is a style of writing web software that favours using the native capabilities and languages of the browser and reducing layers of abstraction (languages and toolchains) on top of them.
Soupault is not like other static site generators — it works on the HTML element tree level. Most SSGs treat HTML as an opaque format that can be generated with templates but cannot be read or manipulated. Soupault treats HTML as a first-class format and that enables many use cases and features that are impossible for other SSGs.
