excalidraw.com is a PWA, but not unsure how helpful it’s going to be as comparison. As mentioned in the comments, success is likely more due to the usefulness of the app rather than the tech used. [e-mail] if you wanna chat.

Unrelated, but this is just a joy to use. Well done.

Unrelated, I'm interested in the tech behind it to build my own PWA. May I ask what tech stack you use. Sorry if it's obvious I'm just getting started
