Excalidraw
Open-source whiteboard that produces hand-drawn-style diagrams.
About Excalidraw
Excalidraw is a free, open-source virtual whiteboard tool available in the browser as a progressive web app (PWA) with a distinctive hand-drawn aesthetic. It requires no account to use — open excalidraw.com and draw immediately. It supports real-time collaboration via shared links, exporting diagrams as SVG or PNG, and an extensive library of community-contributed shapes. As a PWA, it works offline after the first load. The open-source codebase is actively maintained and can be self-hosted or embedded in other applications. Excalidraw is used by developers and technical teams who need quick, clean architecture diagrams, system design sketches, and wireframes with a low-friction, no-setup workflow that any team member can access from a link.
