Here are some screenshots. It is made with Python Flask, light weight and works really well.
It exports comments as json, which you can then use to load comments and regenerate the site.
This requires access to the server to run it and to access Hugo, so this will not work with pure web-hosting, sorry.
So far I have:
Email confirmation of links, after being MX checked so the domain exists, sent in multi-mime
Delete link in email to allow the user control over his data
Checks against throw-away mails
Bayesian anti-spam detection
Allow and block mail addresses
Dictionary for common smileys to be converted to Unicode smileys
Strips html from any input
Admin dashboard
Gravatar with caching option
What does not (yet) work:

Let me know of your wishlist concerning such a feature and I can see what I can do about it.
Cheers.
The only thing you need in Hugo is a short JavaScript function and one template. The are no other dependencies. All Labertasche adds to Hugo are some json files, one per article.
The backend runs on wsgi, so gunicorn with reverse proxy or Apache etc. DB wise anything SqlAlchemy supports.
I am also planning additional scripts to host the admin panel privately, so you can access it via ssh tunnel.
