What it does
Create complex, reactive, persistent web applications by just writing HTML & CSS, without a single line of JavaScript and no server backend. Developed in the Haystack Group at MIT CSAIL and led by Lea Verou . 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 . Mavo’s core functionality can be learned in a few minutes , and is enough to create a vast variety of applications that manage, store, and transform small-scale data. Design your application with the same design freedom and tools as a static webpage . Mavo works with your markup, not against it. Mavo has been designed…from mavo.io
