cmmnts (site) adds a comment section to any website, with a free plan (1 organization, 1 site, 5 pages per site, 500 comments per page, 1 moderator) and a Pro plan at $19/month (5 organizations, 10 sites, 10 pages per site, 20,000 comments per page). If that price is more than you need, here are three cheaper ways to get comments running on a site, ordered from cheapest to most expensive.
Comparison table
| Product | Free tier | Starts at | Best for |
|---|---|---|---|
| cmmnts | Yes | $19/mo | Teams needing multiple orgs/sites |
| Open-source Disqus alternative | Yes (self-host) | Not stated | Developers who can self-host for free |
| JamComments | Yes (10 comments) | $5/mo | Jamstack/static blogs on a budget |
| Hyvor Talk | No (14-day trial only) | $5.4/mo (€5) | Privacy-conscious sites wanting customization |
Open-source Disqus alternative, with hot-reloading and guest commenting
This is a free, open-source comment system that supports hot-reloading and guest commenting without requiring visitors to sign up. It's built for developers who are comfortable deploying and hosting it themselves; the pricing note specifically mentions deploying to a free Heroku instance. It suits hobby sites, side projects, and anyone who wants zero recurring cost. The honest limitation: pricing beyond "free" isn't stated, and self-hosting means you're responsible for uptime, updates, and moderation tooling that hosted competitors provide out of the box.
A statically-rendered, integrated comment system for Jamstack blogs
JamComments is built specifically for Jamstack and static-site blogs, rendering comments statically rather than loading them client-side. The free tier allows up to 10 comments total, which is enough to test it but not to run a live blog for long. Paid plans start at $5/month (also offered as $50/year or $200 lifetime), and include up to 3 sites, unlimited comments, email support, and AI-powered moderation. It suits static-site owners who want a lightweight, integrated option at a low fixed cost. Limitation: the free tier's 10-comment cap makes it more of a trial than a usable free plan.
A Privacy-Focused, Customizable Commenting Plugin
Hyvor Talk is a commenting plugin built around privacy and customization, offering a 14-day free trial with no credit card required rather than a permanent free tier. Paid plans start at €5/month for the Personal tier (about $5.4/month at base rate, though monthly billing works out to roughly $12.96/month), with a Premium tier at €12. It suits sites that want fine-grained control over appearance and data handling. Limitation: there's no lasting free plan, so once the trial ends you need to pay to keep comments live, and the effective monthly price is higher than the headline rate suggests.
How to choose
If you want to pay nothing and can manage your own hosting, the open-source Disqus alternative is the only truly free option here. If you run a static or Jamstack blog and want a low, predictable monthly cost with unlimited comments, JamComments at $5/month is the cheapest paid, hosted option. If privacy and customization matter more than cost, and you're fine paying after a trial, Hyvor Talk is next. cmmnts remains the choice if you need multiple organizations and sites under one account and don't mind the higher $19/month price.
