A highly performant DOM-based web table/grid library written in TypeScript that can render millions of rows at constant time complexity. It uses web workers with shared array buffers for off-thread sorting and filtering, custom virtualization, and its own event loop to maintain 120fps even under heavy load.

Use cases

• render millions of rows in a browser table without lag
• sort and filter large datasets while scrolling at 120fps
• build a financial data grid that never drops frames
• display huge log tables in a web app
• smooth scrolling data grid on mobile phones
• replace slow virtualized table libraries with a faster alternative

When to choose

• you need to display or interact with very large datasets (hundreds of thousands to millions of rows) in the browser
• you require consistent high frame rates while sorting, filtering, and scrolling simultaneously
• browser pixel-height limits of standard virtualization break your current table
• you need performant scrolling on mobile devices

When to avoid

• you need a mature, feature-complete grid with column resizing, custom cell renderers, and full column sort/filter support (still on the TODO list)
• your primary target is iPhone Safari with its low memory limits
• you need a batteries-included enterprise data grid with built-in editing, grouping, or export features
• you prefer a well-documented library with a large community and ecosystem
