Features in a nutshell

• Privacy by design
  Comentario adds no tracking scripts or pixels, and shows no ads. It does collect some high-level statistics, such as visitor's country, browser, and language.
• Multilingual
  Embedded comment engine supports i18n out-of-the-box.
• Role-based access
  Every user gets a role (Owner, Moderator, Commenter, or Read-only) within a specific domain. There's also the global superuser privilege.
• Multiple login options
  • Optional commenting without registration, including anonymous comments;
  • Local authentication with email and password;
  • Social login via Google, Twitter/X, Facebook, GitHub, GitLab;
  • Single Sign-On (interactive and non-interactive).
• Hierarchical comments
  Each comment can be replied to, which results in nested comments. The number of nesting levels is unlimited, but you can opt to limit the maximum visual nesting level.
• Markdown formatting
  Comment text supports simple Markdown formatting rules. So users can use bold, italic, strikethrough, insert links, images, tables, code blocks etc.
• Thread locking
  Commenting on certain pages can be disabled by the moderator by making the page read-only. This can also be done for the entire domain by "freezing" it.
• Sticky comments
  Top-level comment can be marked sticky, which pins it at the top of the list.
• Comment editing and deletion
  Comments can be edited and deleted, either by the author or by a moderator — all of it is configurable.

  Users can choose to get notified about replies to their comments. Moderators can also get notified about a comment pending moderation, or every comment.
• Multiple domains in one UI
  Comentario offers the so-called Administration UI, allowing to manage all your domains, pages, comments, users in a single interface.
• Flexible moderation rules
  Each domain has own settings, automatically flagging comments for moderation based on whether the user is registered, how many approved comments they have, how long ago they registered, whether the comment contains a link etc.
• Extensions
  The so-called extensions link Comentario to external services that check comment text for spam, offensive language, or toxic content. Those services include Akismet, APILayer, and Perspective, and they are configured separately for each domain.
• Statistics
  Comentario collects and displays statistics on views and comments. It includes high-level depersonalised data, such as country, language, OS, browser, and device type. The statistical data can be viewed per-domain or for the entire system.
