React Virtual Renderer

High-performance React virtualization library for large lists, grids, tables, infinite scrolling, dynamic heights, and masonry layouts.

A modern alternative to react-window and react-virtualized with built-in accessibility, dynamic sizing, and TypeScript support.

Why React Virtual Renderer?

Rendering thousands of DOM nodes can severely impact performance.

React Virtual Renderer only renders visible items, allowing your application to handle:

• 10,000+ rows
• Infinite scrolling
• Dynamic item heights
• Large tables
• Chat applications
• Product catalogs
• Masonry layouts

while maintaining smooth scrolling and low memory usage.
