A free, private Disqus alternative
Disqus made comments easy — then turned them into an advertising and tracking product. If you just want your readers to talk back without loading an ad network onto your page, here's an honest comparison.
| Disqus (free) | Margin | |
|---|---|---|
| Price | Free (ads unless you pay) | Free |
| Reader login required | Account/social login prompted | None — just a name |
| Third-party trackers | Yes (ad-tech network) | None |
| Ads on your page | Yes on free tier | Never |
| Page weight | Megabytes of scripts | A few KB, shadow DOM |
| Install | Embed + account | One <script> line |
| Moderation | Yes | Yes (approve-first or publish-now) |
| New-comment alerts | Email (paid tiers for more) | Discord / Slack / webhook, free |
| Your data | Stored & monetized | Yours, no resale |
What you give up leaving Disqus
Disqus has a large shared identity network and years of features (reactions, deep analytics, a central profile). Margin is deliberately smaller: it does clean, private, login-free comments and guestbooks, and nothing you didn't ask for. If you need Disqus's ad-driven scale, keep it. If you want your page fast and your readers untracked, switch.
Switching takes one line
Remove the Disqus embed, drop in Margin, and you're done:
