[Boilerplate: I'm a very happy Octoprint user since the start of the pandemic & I'd like to offer my sincere thanks for this amazing software!]
I listen to the "3D Printing Today" Podcast & read their Google Groups forum. The forum recently mentioned a device called the "Mintion Beagle Camera", which seems to be a standalone camera for taking time-lapse videos of 3D prints in progress. 5 minutes of research on YT revealed the web UI seems quite similar to Octoprint, sharing some elements that (to my knowledge) are unique to Octoprint, as well as overall UI layout. I sincerely hope they're legally licensing your code & everything is above-board.
