Excalicast vs tldraw: recording a whiteboard to video
tldraw and Excalidraw are infinite-canvas whiteboards for drawing; Excalicast adds the recording layer on top of an Excalidraw canvas — it captures your operation stream and microphone audio and renders a narrated MP4 in 16:9, 9:16, 1:1, or 4:5 entirely in the browser.

FAQ
Can tldraw record a video?
