Design & Whiteboards
Design, prototype and brainstorm.
Interface work, loose thinking and durable diagrams pull in different directions. Figma, Sketch and Penpot reward using whatever your collaborators already have open. Excalidraw, tldraw and Miro reward a canvas you can open in two seconds and throw away. Diagrams that must stay correct as the system changes are better kept in text.
Editor's pick
Excalidraw for anything you would otherwise scribble on paper. It opens instantly, the file is yours, and the person you send it to does not need an account to look at it.
