The Problem Every whiteboard app I tried wanted me to sign up, sync to the cloud, or load 2MB of JavaScript. I just wanted a blank canvas. The Solution MindNotes Pro — a drawing app with 3 production dependencies: react, react-dom, zustand Enter fullscreen mode Exit fullscreen mode That's it. No Redux. No styled-components. No axios.
