What is Comments.js?

Comments.js is the easy, extensible way to add a comments section to any website, including static sites like those hosted with GitHub Pages.

Making an account and dropping the HTML snippet into your page (tutorial here) will take five minutes flat.

Comments.js is built atop Zetabase, a cloud-native database built specifically to enable frontend developers to build data-driven web applications with no backend. This means you can extend and customize Comments.js as your business grows and requires more specialized features.

Some benefits of this approach include:

  • It works anywhere: GitHub Pages, Wix, Wordpress, whatever. Take your users — and your comments — with you when you change hosting.
  • Super-simple setup: just follow our simple 3-step guide. It only takes 5 minutes to setup comments on a new site.
  • 100% open and extensible: Comments.js is 100% open-source and is based on Zetabase. Build freely! No vendor lock-in allowed.

Frequently Asked Questions

Who runs the server?

We do! Comments.js is built using Zetabase and by default runs using your account's free-tier storage.

How can a developer extend or customize Comments.js?

Comments.js is 100% open-source, frontend-only code. That means a developer with Javascript skills could extend Comments.js however they please. No vendor lock-in ever!

Is it free?

Yes! Zetabase will be free forever, and Comments.js will always run on a Zetabase free tier.

Does Comments.js work with GitHub Pages and/or Jekyll?

Yes! Simply paste the code snippet you're provided during signup into your posts and comments will appear automagically.

How do users log in?

By default, sign-in with Google accounts is enabled. (Alternatively, users can choose to have their own username/password system.)
