Our Features

ReplyBox is all about making life simpler, so we added everything you need and nothing more.
Clean Commenting


Worry free comments section. Don't spend time getting inundated by spam and focus on your community.
  • Goodbye Spam

    We use Akismet and a few other bright ideas to keep the spammers on the sidelines where they belong.
  • Instant Moderation

    Control all new comments with a manual approval system that’s simple and effective.
Keep them coming back


Make life easier for your users by offering the right amount of features to keep your community engaged and wanting to get involved.
  • Markdown

    Links, lists, quotes, code blocks and even your favorite emojis are all welcome here 💪
  • Natural Discussion

    We've added nested comments so your users can reply direct to any comment they like and share their bright ideas.
  • Always in the Loop

    Anyone can subscribe to email notifications in an instant so that a reply or comment is never missed.
  • Localization

    Reach English-speaking, Spanish speakers, or any language group with our platform, connecting in their preferred language.
  • Pin a Comment

    Highlight a bright idea or spark of inspiration with the click of a button so you never lose it.
  • Comment Upvotes

    A comment doesn't always need a reply. Sometimes all you need is an upvote.

“I'm using ReplyBox on all my sites now for comments. It has an elegant and clean look, and doesn't slow down my page load times by loading lots of scripts.”
