I was resisting posting my OT question on this thread, but I will, briefly: Is there something like Lichess for Go (the board game)? Similar quality and openness.
A couple of years ago, I spent a good little chunk of time searching something out, and I think I recall seeing a few interesting candidates, but I didn't follow through and don't have those results at hand.
