Our verdict on Commentbox.io
Commentbox.io hosts comment sections that website owners embed on their pages. Visitors can sign in with social accounts or email, post comments and replies, and vote, flag, or pin comments. It is aimed at solo operators and small sites that want discussion features and moderation without building a commenting system themselves. The free Personal plan includes 100 comments per month, unlimited page views, and basic moderation tools.
According to the published plans, Professional costs $10 per month and adds unlimited comments, unlimited page views, webhook support, Slack notifications, and single sign-on while retaining basic moderation tools. The annual Professional listing is $100 per year and describes unlimited comments, unlimited page views, and basic moderation tools. Moderation Plus is an optional add-on at $20 per month per group of 5K comments; it adds granular filters, shadow-banning, thread locking and disabling, search and filtering, and up to nine extra moderators. That structure suits sites that need higher comment capacity or more detailed controls, though the listed add-on cost scales by comment group.
The product keeps its scope on embedded website discussions: moderation is available from the dashboard or embedded plugin, users can be blocked for a chosen duration or indefinitely, and published comments can be exported. WordPress and Disqus imports, plus Slack and webhook support, help with migration and notifications. The platform listing is web-only, so organizations seeking broader platform coverage should look elsewhere. Commentbox.io is a fit for small web publishers seeking hosted comments and straightforward controls; sites with higher-volume moderation needs should weigh the add-on, and those requiring non-web coverage should consider an alternative.
