React Virtuoso is a React component library for virtualized rendering of lists, grids, tables, masonry layouts, and chat message lists. It handles variable-sized items automatically without manual height measurements and supports features like grouped sticky headers, endless scrolling, and reverse-scrolling chat interfaces.

Use cases

• render large lists with thousands of items in react
• virtualized chat message list with auto-scroll
• infinite scrolling feed with load more
• grouped list with sticky headers
• virtualized data table with sticky columns
• masonry image gallery layout
• variable height items without hardcoding heights

When to choose

• you need to render very long or unbounded lists in React with smooth performance
• item heights are unknown or variable
• you're building a chat UI, feed, or grouped list with sticky headers
• you want lists, grids, tables, and masonry from one library

When to avoid

• you're not using React
• you only render a handful of items and virtualization adds unnecessary complexity
• you need the commercial VirtuosoMessageList chat component without a license budget
• you need a fully MIT-licensed chat message list component
