Ghost has native comments built in. You don't need Disqus or a third-party script anymore.
The trade-off is that comments are tied to Ghost's membership system. That's what makes them clean and ad-free, and it's also what keeps most readers from using them.
How Ghost native comments work
You enable comments in Ghost Admin under Settings → Membership → Access. You can set commenting to all members or to paid members only.
Members can reply, like comments, and edit or delete their own. Official themes support comments by default; a custom theme may need a small change to render the comment area.
The constraint is the membership requirement. Commenting is limited to logged-in members. A reader who wants to comment has to sign up for a free or paid membership and then sign in. There's no anonymous path.
Why the membership gate filters readers out
A free membership sounds like a low bar. In practice it's still a sign-up form, an email, and a login before anyone can type a word.
Most people reading a blog post arrived from search or a shared link. They'll read, maybe agree, maybe want to say one thing, and then leave. Asking them to create an account first means the comment that would have taken ten seconds doesn't happen. Your comment section ends up reflecting members only, which on most Ghost sites is a small fraction of total readers.
The alternatives, briefly
Before Ghost shipped native comments, most people reached for Disqus. It's a one-line install and readers can use a Disqus login.
The downsides are well known: the free plan shows ads on your site, and the privacy policy permits visitor data to be used for behavioral advertising. There are lighter options too. Self-hosted tools like Remark42 and Isso drop the ads and can accept comments without an account, but you have to run and maintain the server yourself. I went through the full list in this Disqus alternatives comparison.
Each option has a cost: Ghost's native comments ask the reader to sign in, Disqus brings ads unless you pay, and the self-hosted tools ask you to run a server.
A comment box with no login
If the goal is to actually hear from casual readers, the missing piece is a comment box that asks for nothing.
Joey is a hosted comment box you link to or embed below a Ghost post. A reader clicks, leaves a line, and that's it. No membership, no account, no login. They stay anonymous.
It doesn't replace Ghost's member comments. Keep those for your members and add a no-login box for everyone else.
What you own
Reactions collect in a dashboard you control. Read them, reply, and export to CSV whenever you want. Nothing is locked inside another platform, so the data moves with you. No ads on the box, no visitor tracking, and nothing used for AI training.
Ghost's native comments are a real improvement over bolting on Disqus. They just answer one question: what do your members think? A no-login box tells you what everyone else thinks.
