React Data Grid Benchmark: Reproducible Comparison
Open benchmark · June 2026 Compatible React data grids ranked with one deterministic 50,000-row continuous-scroll fixture. Published packages, raw samples, exclusions, and limitations are included.

Measured output
Compatible continuous-scroll results
Gold, silver, and bronze mark the three best values in each compatible metric. Lower is better except estimated FPS.

Scorecard
Gold, silver, bronze
Rank points across 10 compatible metrics. Lower score wins. Incompatible adapters are excluded from scoring instead of being mixed into the ranking.
Overall medal ranking across compatible metrics | Library | Rank | Score | Category wins or best rank | Analysis | | --- | --- | --- | --- | --- | | Gold React Data Grid | 1 | 12 | JS gzip, Ready, Jump scroll | Best overall in this fixture: smallest bundle, lowest heap, lowest long-task time, and top smoothness. | | Silver Ace Grid Core | 2 | 27 | Dropped frames | Strong on ready time, scroll settle, low DOM count, and smooth continuous scroll; memory is the main gap. | | Bronze TanStack Table + Virtual | 3 | 32 | Best rank #2: JS gzip, Ready, Jump scroll | Smooth continuous scrolling, but heap growth is high for this fixture. | | AG Grid Community | 4 | 37 | Best rank #2: Heap ready, Heap after scroll, Long tasks | Balanced memory profile and low long-task cost, but continuous-scroll FPS trails the leaders. | | Handsontable | 5 | 40 | Mounted cells | Lowest mounted-cell count, but startup and long tasks are expensive here. |
Metric guide
What the numbers mean
JS gzip Reachable JavaScript after gzip. Lower means less code to download and parse. CSS is excluded.
Ready median The middle of 10 runs from navigation until the adapter mounts and two animation frames pass. Lower is better.
Scroll settle Time for one large vertical and horizontal scroll jump plus three animation frames. It is not an FPS score.
Mounted cells Body cells in the DOM after the scroll. Fewer cells reduce DOM work, but very low overscan can expose blank edges.
Methodology
Same fixture, repeatable protocol
Shared fixture
- 50,000 deterministic rows and 20 fixed-width columns
- 36 px rows in a 1,200 × 600 px viewport
- Two editable columns, sorting, filtering, and virtual scrolling
- No network requests, grouping, images, or paid-only features
Measurement protocol
- Production bundles in headless Chrome
- Three warmups discarded, then 10 fresh browser contexts
- The same vertical and horizontal scroll jump for compatible grids
- Every raw sample committed with exact package versions
**Excluded from ranked tables:** MUI X Data Grid Community (MUI X Community forces pagination and limits pages to 100 rows.). Excluded adapters remain available in the live fixtures and raw JSON.
Published-package verification
Ace Grid 1.0.15 vs AG Grid
Thirty alternating-order runs, five discarded warmups, and a fresh browser context for every sample.

**On this machine:** Ace Grid reached ready 12.2% sooner, settled the scripted scroll 19.5% sooner, and mounted 140 fewer cells. View all raw samples.
Interaction health
Memory, long tasks, and smoothness
Five measured runs after one warmup. Each run performs a two-second continuous scroll in a fresh Chrome context.

Analysis
What the results show
Fastest interactive path
React Data Grid leads the overall scorecard because it combines the smallest runtime heap, no median long-task time, and near-120 FPS continuous scrolling.
Ace Grid vs AG Grid
Ace Grid remains ahead of AG Grid on ready median, jump-scroll settle, mounted cells, continuous-scroll FPS, and dropped frames. AG Grid currently uses less heap and posts lower long-task totals.
Memory-sensitive apps
Heap-ready and heap-after-scroll numbers favor React Data Grid, followed by AG Grid. Ace Grid's current row-adapter path trades more heap for fewer mounted cells and smoother continuous scrolling.
Compatibility rule
Libraries are ranked only when they expose the same continuous 50,000-row virtualized surface. Pagination-limited adapters stay in raw data, not the leaderboard.
