Vanta.js is a JavaScript library that lets you add animated 3D effects to web page backgrounds with a few lines of code. Built on three.js and p5.js, it ships with a number of ready-made effects such as waves, fog, nets, and flocks of birds; you only specify the target element and color options to get a background that reacts to mouse movement. It is used to decorate landing pages and hero sections, and it provides options to adjust effect intensity with mobile performance in mind.
