really random question - but what is used to create the images in this blog post? I see this style quite often but never been able to track down what is used.

https://d2lang.com/

https://www.drawio.com/

For something a bit lower level, try:

https://roughjs.com/

It's what powers the sketch-like look from many of the sites above.

I suspect they used Excalidraw [1]. It's a nice, quick tool for this kind of sketching, and supports collaborative drawing.

if you look at the metadata of each png, you will find the application/vnd/excalidraw/json field that contains the image in excalidraw format.
