Excalidraw vs tldraw: Drawing Tools & Canvas SDKs
Choose Excalidraw when sketch-like diagramming and the Excalidraw editor fit the intended experience. Choose tldraw when a React canvas SDK with custom shapes and interactions fits the product being built.
For a team choosing a browser whiteboard, test everyday collaboration first. For a team embedding a canvas, the decision is about APIs, licensing, persistence, and operation. Keep these contexts separate: a demo board is not proof that a production multiplayer application is ready.
Excalidraw
Excalidraw is a virtual whiteboard for sketch-like diagrams, with an open-source editor that can be embedded in applications. Distinguish using the hosted drawing tool from building a product around its library. For a team workshop, test the everyday collaboration and saving workflow; for an embedded canvas, examine the integration contract.
tldraw
tldraw offers a browser whiteboard and a React canvas SDK. The SDK supports custom shapes, tools, interfaces, persistence, and multiplayer implementations. These are different evaluation contexts: using a ready-made canvas for a workshop is not the same commitment as building and operating a custom collaborative application.
Feature comparison
| Feature | Excalidraw | tldraw |
|---|---|---|
| Working unit | A sketch-like canvas holds shapes, text, arrows, and imported visual material. | The canvas provides drawing tools and shapes; the SDK supports custom content. |
| Organization | Drawing elements create informal diagrams without requiring a high-fidelity design system. | Custom shapes and interactions can adapt a canvas to an application domain. |
| Collaboration | The hosted editor supports collaborative drawing workflows; embedding is a separate integration. | Multiplayer and persistence need deliberate implementation decisions in an SDK-based product. |
| Workflow connections | The open-source editor library can form part of a custom application interface. | React and TypeScript APIs support building a canvas into your own application. |
| Access and operation | A hosted session and your own embedded deployment have different storage responsibilities. | Check SDK licensing and who operates sync, storage, and application authentication. |
| Decision in practice | Sketch-like diagramming and the Excalidraw editor fit the intended experience. | A React canvas SDK with custom shapes and interactions fits the product being built. |
Excalidraw pros
Sketch-style diagrams encourage discussion before visual polish.
An open-source editor supports inspection and application integration.
A small drawing can communicate a system or process without a large workspace.
Excalidraw cons
A diagram still needs an agreed saving and ownership workflow.
Embedding requires application engineering rather than merely sending a board link.
Pricing: Distinguish the open-source editor license, hosted product options, and the cost of operating an embedded deployment. Verify current commercial terms for the chosen use.
tldraw pros
The SDK exposes custom shapes, tools, and interaction possibilities.
React integration supports a canvas embedded in an existing product.
Multiplayer and persistence capabilities support collaborative application development.
tldraw cons
An SDK-based product needs engineering for identity, storage, and operation.
Production SDK deployment needs a valid license key: commercial use needs a commercial license after evaluation; noncommercial use can qualify for a discretionary hobby license.
Pricing: The SDK can be used in development under its default terms. Production requires a valid trial, commercial, or hobby license key. Use the trial for evaluation, budget a commercial license for ongoing commercial production, and check eligibility for noncommercial hobby use. Include sync infrastructure, storage, and maintenance; hosted whiteboard access is separate.
