Live update

Comentario supports the so-called Live update — a mechanism that delivers new or updated comments on the page that is already open, without the need to reload the page.


A comment is, just like domain, a basic building block in Comentario. A comment represents a piece of text, multiple comments are arranged in a tree structure called comment tree.

Comment tree

The term comment tree, also called comment thread, means that comments are organized in a tree structure, so that comments can have children — which we call replies.


The concept of domain is central to Comentario: it is a basic building block.

Domain page

A domain page represents a website page on a certain domain. A page corresponds to a specific URL.


Comentario allows to write comments with rich formatting by using the so-called Markdown format (or language).


There are two kinds of permissions in Comentario: the superuser permission and a number of user domain roles.

Sticky comment

If a comment has no parent, we call it a root or a top-level comment. A root comment can be made sticky, which will pin it at the top of the comment tree.
