Top 7: Best Open Source Self-Hosted Comment System Alternatives to Disqus

As a blog owner, i remember how difficult it was to me to decide whether i should use an open source solution for the commenting system of my blog. After a while, i decided to move on with Disqus as for a starter, it's a quite good solution, however as you progress with your blog, you will notice that in many ways, it's not the best solution at all. For a lot of people, because of the privacy and others, like me, for the pricing. Disqus offers a free plan up to some point, but once your blog reaches a significant amount of views, you will have to move to the pro plan, which in some way, it's a lot considering that you can achieve the same if you decide to move to a self hosted open source solution (yeah, we will stop using disqus once we reach the 50K daily views that they offer for the pro plan [USD $9]).

In this top, we will share with you 7 open source solutions of commenting systems for blogs and static pages that you can self-host on your server.
