Show HN: A reproducible React data grid benchmark with raw browser samples
A new open-source benchmark lets developers test React data grid performance using raw browser samples, providing reproducible results for comparing speed and responsiveness across different grid libraries.
Background
- React data grids are UI components for displaying and editing large tabular datasets in the browser (like spreadsheets inside a web app). Examples include AG Grid, MUI X Data Grid, and React-Data-Grid.
- This is a reproducible benchmark that measures real browser performance of various open-source and commercial React data grids, using actual rendered frames rather than synthetic metrics.
- It includes "raw browser samples" — logged runtime data (FPS, interaction latency, memory usage) from real test runs, so others can verify or reuse the results.
- The author, Vyacheslavitashev (Vitashev), is a developer who contributes to the React-Data-Grid library. The benchmark addresses a common pain point: choosing a grid library with good performance for large datasets, where marketing claims often outpace real measurements.
