Mavo is an HTML-based language and JavaScript library for building small-scale data-driven web applications by writing only HTML and CSS, with no JavaScript or backend required. It extends HTML with attributes for data management, storage, editing, and reactive expressions, and can also serve as a declarative front-end framework for JS developers.

Use cases

• build a data-driven website without writing JavaScript
• create an editable homepage with in-page content editing
• store form data in the cloud or locally via an HTML attribute
• build a small CMS without a server backend
• make reactive UIs declaratively as a front-end framework
• let non-programmers create web apps
• upload images via drag and drop without code

When to choose

• you want small-scale data-driven apps with no JS or backend
• you or your users have no programming experience
• you want in-page editing instead of a traditional CMS
• you want a declarative, reactive alternative to JS frameworks

When to avoid

• you need large-scale, high-performance applications
• you need complex custom business logic or backend control
• your team prefers conventional JavaScript frameworks
• you need fine-grained control over data storage and APIs
