CollabyDraw

Web-based collaborative whiteboard with end-to-end encrypted rooms, no account needed.

Webfree

CollabyDraw is a free web-based collaborative whiteboard for real-time sketching and brainstorming, usable without creating an account. Rooms are end-to-end encrypted so the server hosting the session cannot read what participants draw, and a standalone offline mode is available for solo use. It is aimed at remote teams and privacy-conscious users who want a shared drawing canvas without exposing their content to the server.
