No, Offpunk it's command line driven, it just happens it can output images due to sixel support (and maybe in a near future with the w3m's image displaying tool).

We use Chafa but I’m curious. Are you planing to contribute something related to w3m?

You could also take a look at chafa[0] for supporting terminals without sixel.
