Congrats on launch, fantastic work! The smooth experience is impressive. I launched an online video editor, Chillin - https://chillin.online, which is also WebGL-based and renders very quickly. I'm interested to know if Repaint will migrate to WebGPU, as Chillin is planning to do so. I believe that web apps using WebGPU for rendering can be even faster than native apps!
We're not sure. WebGPU seemed too early to us. But as I got deeper into WebGL, the ability to do more arbitrary computation sounded more and more appealing. I wouldn't be surprised if migrated down the road.
