[Muut](https://muut.com) similar to Disqus is a discussion service that unlike Disqus with only allows commenting lets you to embed the discussion as an embed to your website so you can have a complete discussion section on your website.
The other great feature of Muut is it supports Markdown. Which means that if I can write posts in Markdown you can write comments in it too.
I switched back to Disqus because Muut free plan is very limited.
