Clusterize.js is a tiny vanilla JavaScript plugin that efficiently renders very large data sets in tables, lists, or divs. It splits content into clusters and only keeps rows near the current scroll position in the DOM, emulating full list height for a native scrollbar.

Use cases

• render a table with hundreds of thousands of rows without lag
• display large ordered or unordered lists in the browser
• smooth scrolling for huge datasets in a web app
• avoid DOM pollution when showing big lists
• add virtual scrolling to existing markup without a framework

When to choose

• you need to display very large lists or tables with plain JavaScript
• you want a tiny dependency-free virtual scrolling solution
• your project uses no framework and you want minimal setup

When to avoid

• you already use a framework with built-in virtualization like react-window or vue-virtual-scroller
• you need complex row heights or dynamic layouts that simple clustering can't handle
• your lists are small enough that plain DOM rendering is fine
