 ## Limitations when running egui on the web
-`eframe` uses WebGL (via [`glow`](https://crates.io/crates/glow)) and Wasm, and almost nothing else from the web tech stack. This has some benefits, but also produces some challenges and serious downsides.
+`eframe` and egui compiles to Wasm using either WebGPU (when available) or WebGL2 for rendering, and almost nothing else from the web tech stack. This has some benefits, but also produces some challenges and serious downsides.
 
 * Rendering: Getting pixel-perfect rendering right on the web is very difficult.
 * Search: you cannot search an egui web page like you would a normal web page.
