Sometimes you just need a blank canvas to sketch an idea, no accounts, no feature gates, no learning curve. TLDraw is an open-source infinite whiteboard that loads instantly in your browser, supports real-time collaboration, and comes with an AI-powered make-it-real mode that turns your stick-figure sketch into actual code.

Main Features

• Instant Infinite Canvas: Open tldraw.com and start drawing immediately. Zoom, pan, and scroll across an infinite whiteboard with zero lag. No account, no install, no friction.
• Real-Time Multiplayer: Share a link and collaborate live. Watch teammates draw in real time with smooth cursors and presence indicators. Perfect for remote whiteboarding sessions.
• AI Make It Real: Draw a rough wireframe or UI mockup with basic shapes, select it, and TLDraw's AI generates actual HTML/CSS code from your sketch. The fastest prototyping loop around.
• Comprehensive Shape Library: Rectangles, arrows, sticky notes, frames, embeds, text, images, and freehand drawing tools, everything you need for diagrams, wireframes, and visual notes.
• Fully Open Source: The entire codebase is on GitHub under a permissive license. Embed TLDraw in your own app, customise the behaviour, or self-host, no vendor lock-in.
• Embed Anything: Paste a YouTube link, tweet URL, or image and it renders inline. Turn a whiteboard session into a multimedia reference board without tab-switching.
• Export and Persist: Save boards as JSON, PNG, or SVG. Pick up where you left off with auto-save. Share a read-only link so stakeholders can view without accidentally editing.
• Developer SDK: The tldraw npm package lets you embed a full whiteboard into your own React app with a few components. Dozens of startups have built collaborative tools on top of it.

Who Should Use It?

• Designers and Developers: Sketch UI layouts on a shared whiteboard, then use AI to turn them into working code in seconds. The gap between idea and prototype has never been smaller.
• Remote Teams: Replace physical whiteboards with an infinite digital canvas that everyone can see and edit simultaneously. No more holding your notebook up to the webcam.
• Educators: Draw diagrams, annotate concepts, and share lecture boards with students in real time. Record sessions as JSON for replays and review.
• Startup Founders: Brainstorm product ideas, map user flows, and sketch wireframes with your team on a zero-friction canvas. No tool onboarding, just start drawing.
• Product Managers: Map feature flows, brainstorm with sticky notes, and export clean SVGs for documentation in minutes. The AI mode turns napkin sketches into clickable prototypes.
• Builders and Makers: Use the SDK to add collaborative whiteboarding to your own product. TLDraw handles the hard parts, real-time sync, undo/redo, shape collision, so you don't have to.
• Anyone Who Just Wants to Sketch: If you've ever needed to draw a quick diagram and didn't want to launch a full app, sign up, or pay, tldraw.com is ready before you finish typing the URL.
