+## WebGL Renderer [<span class="plan-premium"></span>](/x/introduction/licensing/#premium-plan 'Premium plan')
+
+Heatmaps can contain a large number of cells.
+To improve performance when rendering many cells, you can use the WebGL renderer by setting the `renderer` prop to `'webgl'`.
+
+The WebGL renderer has some limitations compared to the SVG renderer:
+
+- The `cell` slot is not supported;
+- The heatmap cell cannot be customized using CSS;
+
+The following example showcases a heatmap with approximately 8800 cells rendered using WebGL.
