Two open-source whiteboard tools with overlapping audiences but different vibes — pick based on aesthetic and how much you'll customize the canvas.
Pick Excalidraw when you want the hand-drawn sketch aesthetic for architecture diagrams, brainstorming, and shareable scribbles — it's the go-to for engineers who want a whiteboard, not a design tool. Pick tldraw when you want a more polished general-purpose canvas you can embed and extend with a real SDK, especially if you're building canvas-style features into your own product.
