Mavo
Create web applications entirely by writing HTML and CSS
... wrestling with CMSes and servers! Multimedia uploads to your page via drag & drop, pasting, or browsing, without a single line of code. Perform calculations right in the HTML, that update when needed. No need to write JavaScript! Mavo uses familiar HTML-based syntax and can be used even by people with no programming experience. This is not wishful thinking; it’s published, peer-reviewed research.
