tldraw
tldraw is a free, browser-based collaborative whiteboard you can open instantly without creating an account. Open the site and you land on a full canvas for drawing, diagramming, and visual thinking with others online.
The product is built around speed and low friction. There is no signup wall before you start sketching, and the interface keeps the canvas front and center. Sign in when you want to share a board so teammates can join the same session.
tldraw runs on mobile, tablets, and desktop in the browser, which makes it useful for quick brainstorms, workshops, and async visual notes. The homepage also points builders to the tldraw SDK at tldraw.dev for embedding the same canvas technology in custom apps.
