About VvvebJs
VvvebJs is a drag and drop page builder library written in vanilla JavaScript. It ships without dependencies and without a build step, so the editor runs directly in the browser from a plain HTML file rather than from a compiled bundle. The project lives in the JavaScript ecosystem and sits in the low code and no code tooling space: it is a library and editor surface rather than a finished product, and it is distributed under the Apache 2.0 license.
