The windows to the left appear to use Roboto Mono.

The window to the right seems to use the same typeface, no?

Partially—they have a demo/sandbox version and some of it is actually Courier....

Ah, ok, I didn’t watch the entire video.

So, to wrap it up: Roboto Mono, some Courier, and plain Roboto for the titles of the windows.
