Disqus (pronounced discuss) is a worldwide blog comment hosting service for web sites and online communities that use a networked platform. The company's platform includes various features, such as social integration, social networking, user profiles, spam and moderation tools, analytics, email notifications, and mobile commenting. It was founded in 2007 by Daniel Ha and Jason Yan as a Y Combinator startup.

In 2011, Disqus ranked #1 in Quantcast's U.S. networks with 144 million monthly unique U.S. visits.[3] Disqus has been featured on many major publications, such as CNN, The Daily Telegraph, and IGN, and about 750,000 blogs and web sites.[4]


Disqus was first developed in the summer of 2007 as a Y Combinator startup headed by Daniel Ha and Jason Yan, who were undergraduates at the University of California, Davis. Disqus was first incorporated and launched on October 30, 2007.

In early 2011, Disqus raised $10 million in funding from North Bridge Venture Partners and Union Square Ventures.[5]

According to a study by Lijit, Disqus was used by 75% of websites in March 2011 who used a third-party commenting or discussion system.[6]


The Disqus comment widget is written in JavaScript and is powered by a back end primarily written in Python using the Django framework.

Business model

Disqus operates on the freemium financial model similar to Dropbox and Evernote. The service is free to use for both commenters and web sites. Web sites can pay fees to unlock additional features.

In November 2010 Disqus began officially offering three add-on packages for web sites: Plus for $19/month, Pro for $199/month, and VIP starting at $999/month.[7] In mid-2011, the Plus package was removed and Pro was increased to $299/month.

Starting July 2012, Disqus offered just two premium packages, the VIP package and a single-sign-on-only package for $99/month.

Premium packages were quietly phased out beginning March 2013.

On January 4, 2017 Disqus announced new premium packages rolling out in March 2017.[8] A later blog post clarified that over 95% of sites using Disqus, mostly personal blogs and non-commercial sites, will be unaffected by the new premium model.[9] Pricing is as follows: [10]

  • Basic - Free, ad supported.
  • Plus - $10/month - For sites with < 50,000 daily pageviews.
  • Pro - $99/month - For sites with < 250,000 daily pageviews.
  • Business - Sites with > 250,000 daily pageviews will be contacted by Disqus directly with pricing.


Disqus Tiers

As of 2017, Disqus' tiers for publishers include:[11][12][13]


Disqus Basic is a free, ads supported plan. It includes access to the core functionality of Disqus, including:

  • Engage comments plug-in
  • Advanced spam filtering
  • Moderation tools
  • Basic analytics
  • Configurable ads
  • Real-time discussions
  • Responsive web support
  • iOS and Windows apps
  • Photo and video support
  • Audience ownership
  • Google Perspective to combat toxic comments


Disqus Plus includes all the features of Basic, plus the ability to turn off advertisements.


Disqus Pro includes all features from Plus and several advanced features:[14]


Disqus Business is configurable based on a site's needs.

Language support

Both the Disqus site and comment system were translated into more than sixty languages in 2011. With the introduction of the new Disqus in 2012, language support dropped to seven languages[15] and even though Disqus accepts applications for new languages,[16] only one has been added since bringing the current number of supported languages to eight as of 2013.

Disqus is now available in "dozens of languages" thanks to crowd-sourced translation on Transifex.[17]

Criticism and privacy concerns

Privacy issues have been noted as inherent in the use of services like Disqus, which serve their content through third-party JavaScript widgets.[18][19][20]

As with other embedded web widgets, such as like buttons, the Disqus widget acts as a web bug which tracks a user's activities, even when they are not logged in, across different sites that use the Disqus commenting system. Information tracked by Disqus, which may be disclosed to third parties, includes pseudonymous analytics data, such as a user's IP address, their web browser version and installed add-ons, and their referring pages and exit links.[21] Although these data are referred to by Disqus as "Non-Personally Identifiable Information", such data, when aggregated, has been shown to be usable for de-anonymizing users.[19]

Disqus has also been criticized for publishing its registered users' entire commenting histories, along with a list of connected blogs and services, on the publicly viewable user profile pages.[22] The option to keep profile activity private was later added.

Users wishing to avoid these issues may opt to install a privacy-enhancing web browser extension, such as Ghostery, NoScript, or DoNotTrackMe, which identify widgets such as Disqus as web bugs,[23][24] and allow them to be blocked; this renders Disqus-powered commenting sections unviewable.

Disqus does not moderate communities which use its service,[25] leading to controversial moderation in some communities. Disqus only intervenes when the Terms of Service have been violated, leading to criticisms that Disqus allows racist and otherwise offensive content to be created on the platform.

Disqus also was criticized for not giving users control over who follows them. Prior to 2014, any user could follow any other user, but a user being followed could not control or block who was following them, which led to harassment among some users.[26]

If Disqus shuts down, hundreds of millions of comments would be wiped away from a wide range of sites, since by the very nature of the service, comment content is not being managed locally by sites implementing the service. However, it is possible for site administrators to export all of their comments as an XML document which can then be ported into other commenting systems.[27]

In September 2014, it announced an update to its privacy policy: "Disqus will be using anonymous interest data for content personalization and ad targeting."[28]

2013 security breach

In 2013 a Swedish group called Researchgruppen obtained and exposed a large number of anonymous Disqus identities through the application programming interface (API).[29] The group cooperated with the Bonnier tabloid Expressen, who subsequently visited some of the commentators in their homes, confronting them with allegedly racist, misogynic, and derogatory sentiments. Researchgruppen said their database contained millions of comments from Disqus users around the world who are at risk of de-anonymization.[30][31][32] In March 2014, Expressen and Researchgruppen won the investigative reporting award Guldspaden.[33]

Issues with delete button

Previously, if a user attempted to delete their comment, Disqus "anonymized" their comment by changing the author to a Guest user, without removing the content of the body itself[34]. The only recourse at that time was to flag the comment, contact the site moderator to delete the anonymized Guest comment, or to remember to edit out the body of the comment before deleting a comment.

In April 2015, Disqus revised their Delete button to completely delete a comment from the website.[35][36]
