You might try posting this under a "Show HN", and/or reconsidering the title. This looks like an interesting and thoughtful tool with a clear purpose, and this title doesn't convey that.
Ok, thank you so much! It's always hard to come up with a catchy title..
Perhaps you should also make web wrappers over more traditional open source tools like PySCF or Psi4, to compare with MACE. With these additions I think this would be a significantly better tool than the proprietary WebMO. (Have you heard of WebMO before?)
