Self-Hosted Alternatives to Disqus

Why Replace Disqus?

Disqus was the default comment system for blogs and websites for a decade. Then it became an advertising company that also hosts comments.

The current state of Disqus:

• Advertising injection — The free plan injects ads into your comment section. These ads are chosen by Disqus, not you, and they’re often low-quality clickbait (“You Won’t Believe What This Celebrity Looks Like Now”).
• Tracking — Disqus loads 10+ third-party tracking scripts per page load. It tracks your visitors across every Disqus-enabled site on the internet, building advertising profiles without consent.
• Performance — Disqus adds 2-5 seconds to page load time and loads 1-2 MB of JavaScript. On a static site optimized for speed, Disqus is the biggest performance bottleneck.
• Pricing — The ad-free plan (Disqus Plus) starts at $12/month. The Business plan is $115/month. To avoid ads on YOUR website’s comments, you pay Disqus monthly.
• Data ownership — Comments are stored on Disqus servers. If Disqus goes down, changes terms, or shuts down, you lose your community’s discussions.
• SEO impact — Disqus loads comments via JavaScript, which search engines may not index. Self-hosted solutions can render comments server-side.

Self-hosted comment systems eliminate all of this: no ads, no tracking, sub-second load times, full data ownership, and zero monthly cost.

Best Alternatives

Remark42 — Best Overall Replacement

Remark42 is a privacy-focused, lightweight comment engine that does everything Disqus does without the bloat. It supports multiple authentication methods (anonymous, email, Google, GitHub, Facebook, Telegram), nested comment threads, voting, image uploads, Markdown formatting, and real-time updates via WebSockets.

The standout features: zero tracking, a single Go binary under 50 MB RAM, and full data export/import. Remark42 loads in milliseconds, not seconds — your site stays fast. It also includes built-in RSS for comment feeds, email notifications for replies, and admin tools for moderation.

Remark42 has a built-in Disqus migration tool that imports your existing comments and preserves threading.

Feature	Remark42 Highlights
Anonymous commenting	Yes (configurable)
OAuth providers	Google, GitHub, Facebook, Telegram, email
Nested threads	Yes
Voting	Up/down
Image uploads	Yes
Email notifications	Yes
RSS feeds	Per-page and site-wide
Disqus import	Built-in migration tool
Admin panel	Yes (moderation, user management)
RAM usage	~30-50 MB
Embed size	~15 KB JS

Isso — Best Lightweight Option

Isso is a minimal comment server inspired by Disqus but focused on simplicity. It’s written in Python, stores comments in SQLite, and the entire embed script is under 12 KB. If you want the simplest possible self-hosted comment system, Isso is it.

Isso supports threading, Markdown, email notifications, and admin moderation — the essentials, nothing more. It has a built-in Disqus importer for migration.

The trade-off: no OAuth login (comments use name + email), no voting, no image uploads. Isso covers the core commenting use case with minimal complexity.

Commento — Best Privacy-Focused

Commento (or its actively maintained fork, Comentario) is built specifically as a privacy-respecting Disqus replacement. It highlights privacy as a core feature: no tracking, GDPR-compliant by design, and the embed loads in under 10 KB.

Commento supports OAuth login (Google, GitHub, GitLab), nested threads, moderation dashboard, markdown, and sticky comments. It also has a commercial hosted option if you want the privacy benefits without self-hosting.

Giscus — Best for Developer Blogs

If your site is on GitHub Pages or uses a GitHub-connected workflow, Giscus uses GitHub Discussions as the backend for your comment system. Comments are actually GitHub Discussion threads — readers authenticate with GitHub and comment via the familiar GitHub interface.

Giscus is zero-cost, zero-maintenance (GitHub hosts everything), and perfectly suited for developer audiences. The limitation: it requires GitHub authentication, making it unsuitable for general-audience sites.

Migration from Disqus

All major self-hosted alternatives support Disqus import:

Export from Disqus

1. Go to Disqus Admin → Community → Export
2. Disqus generates an XML file with all comments, threads, and user data
3. Download the XML file

Import to Remark42

# Built-in Disqus importer
docker exec remark42 remark42 import \
  --provider=disqus \
  --file=/srv/var/disqus-export.xml \
  --site-id=your-site-id

Remark42’s importer preserves:

• Comment text and formatting
• Thread structure (parent/child relationships)
• Author names and emails
• Timestamps
• Votes

Import to Isso

# Built-in Disqus importer
isso --conf /etc/isso.conf import disqus-export.xml

Import to Commento

Commento includes a Disqus import tool in its admin dashboard. Upload the XML file and it maps threads to your site’s URLs automatically.

Post-Migration Checklist

1. Replace the Disqus embed script on your site with the new comment system’s embed
2. Verify comments appear on existing pages (URL matching is critical)
3. Remove Disqus tracking scripts from your site’s HTML
4. Verify page load time improvement (expect 2-4 second reduction)
5. Delete your Disqus account once you’ve confirmed the migration is complete

What You Give Up

• Account portability — Disqus accounts work across every Disqus-enabled site. Self-hosted comments are per-site (though OAuth mitigates this for logged-in users).
• Spam filtering — Disqus has years of spam detection data. Self-hosted solutions have basic spam protection. You may need to add Akismet or manual moderation.
• Community features — Disqus profiles, follower systems, and cross-site notifications. Self-hosted comments are simpler.
• Social proof — High comment counts on Disqus can signal popular content. New self-hosted comment sections start at zero.
• Moderation at scale — If you get hundreds of comments daily, Disqus’s moderation tools are more mature. Self-hosted tools work fine for small to medium sites.

For most blogs and websites, the migration is straightforward and the improvement is dramatic: faster page loads, no ads, no tracking, and full ownership of your community’s discussions.
