Introducing tldraw: Infinite Canvas Whiteboarding Built for the Web
tldraw is a fast free web whiteboard and React infinite-canvas SDK for collaborative sketching and embedded canvas products.
Introducing tldraw: Infinite Canvas Whiteboarding Built for the Web
Marketing, product, and engineering teams still sketch flows in slides, then redraw them in three other tools before anyone can collaborate. tldraw is a fast, free web whiteboard — and an infinite-canvas SDK for React — so teams can think together on a shared canvas without leaving the browser.
tldraw sits next to storyboard-first explainers: use it when the job is sketching systems, UX flows, and workshop boards; use a storyboarded explainer when you need a finished narrative for an audience that will not join the canvas.
What tldraw does
tldraw is a web-native infinite canvas. The consumer app at tldraw.com is a “very good free whiteboard.” The developer product at tldraw.dev ships the same canvas as a React SDK teams embed inside their own products.
Core surfaces:
- Free multiplayer whiteboard — shapes, arrows, sticky notes, drawing, and real-time collaboration in the browser
- Infinite canvas SDK — drop tldraw into React apps for custom whiteboards, editors, and creative tools
- Fast, opinionated UX — keyboard-friendly, low-friction sketching that feels closer to a notepad than a heavy diagram suite
- Extensible for builders — APIs and an open approach so product teams can ship canvas features without reinventing the engine

Who it is for
Product designers, engineers, workshop facilitators, and teams that need a shared sketch surface — plus startups building canvas features who would rather adopt a proven SDK than maintain one.
Where it fits in a content stack
tldraw lives in the thinking / collaboration layer. Pair it with interactive proposals or demos when a prospect needs a polished leave-behind, and with storyboarded explainers when the audience needs a clear teaching narrative rather than a live board.
Why it matters now
Async and hybrid teams still lose hours translating whiteboard photos into “official” docs. A browser canvas that is both a daily whiteboard and an embeddable SDK reduces that translation tax.
Quick tips if you try tldraw
- Start on tldraw.com for workshops; graduate to the SDK only when you need the canvas inside your product.
- Name frames early so async teammates can jump to the right region.
- Use arrows + short labels instead of long paragraphs on the board.
- Export or screenshot key frames into decks or docs after the session.
- Keep exploratory sketches separate from the “source of truth” system diagram.
How teams use tldraw day to day
A product trio opens a shared board for a discovery workshop, then pins the agreed flow beside the sprint board. An engineering team embeds the SDK so customers can annotate support diagrams inside the app. Marketing sketches campaign structures on the free whiteboard, then turns the winning path into a storyboarded explainer for launch.
A closer look at the workflow
Most whiteboard sessions fail after the meeting ends. Screenshots pile up in Slack; the “final” Miro board becomes a graveyard. tldraw’s lightweight web app makes it cheap to open a board for a 20-minute decision, while the React SDK lets product teams embed the same interaction model inside customer-facing tools — support annotation, collaborative planning, or creative canvases — without licensing a separate whiteboarding vendor for every use case.
For developer teams evaluating canvas infrastructure, tldraw’s open posture and React focus matter: you ship product features, not a fork of a closed editor. For facilitators, the free whiteboard is enough to replace sticky-note photos for many workshops.
Soft close — related tool
If you also need concept → storyboard → animated or whiteboard explainer / Reels (not talking-avatar presenters), see Scro Explainer. Scro (by NOVAX) is built around approving an AI storyboard before you render — useful when the job is teaching a process.
