Discourse is an open-source platform for creating an online forum, comment, chat rooms, or mailing list system. In this tutorial, we see the steps to install Discourse on Debian 11 Bullseye using the command terminal.
With time, the internet forums have changed now. They are no anymore with old, monotonous designs. Anyone who has ever used or been a member of phpBB or vBulletin, already understands how forums work and their importance in the internet world. But in the last few years, website operators seem to be far less interested in their forum. However, Discourse finds its way and even gets popular among the community because of the modernization of the forum they are offering with their software.
It was launched in 2014, hence has been around for 7 years now, Discourse is Ruby-based forum software. In addition, the creators – including Stack Overflow co-founder Jeff Atwood – integrated various newer elements that we know from social networks or comment systems such as Disqus.
Apart from the self-hosting open source edition, the makers of Discourse also offer their hosting solution for between $100 and $300 per month or depending upon the custom solution; just like WordPress.com.
