Reminds me of boardspace, though the UI is much cleaner.

You should try to add the Gipf games at some point, they are very wonderful!

I was just going to recommend boardspace.net here! It also somewhat recently went open source: https://github.com/ddyer0/boardspace.net

It clearly is stuck in the Java Applet era where it started but Dave eventually made an Android port and modern Java has no issues running it!
