Small setup.
Good questions.
Everything you need to get the conversation started.
Explore the docsHow do I add comments to my website?
Create an account, register your site, and copy the iframe and JavaScript snippets into your pages. A stable identifier gives each page its own discussion. Follow the integration guide.
Will it work with my static blog?
Yes. Commentsy works on blogs, static HTML sites, and other websites that allow an iframe and JavaScript. Your site does not need its own comment backend.
Do my visitors need an account?
No. Visitors can post as guests or sign in. Turn on guest approval to review guest comments and replies before they appear publicly.
Can I self-host Commentsy?
Yes. Commentsy is open source. Get the code and setup instructions on GitHub to run your own instance, with custom light and dark themes.
