11 Best Open source Forum Software for Free Online Discussion (2022)

Apart from your website if you want a free self-hosted online forum software then you stumble upon the right place. There are lots of open-source forum software platforms available where you can start your online discussion board in no time. But things get stuck when you want to start your forum and are a little bit confused about which platform is best for you. Many forum platforms are available free of cost and easy to handle just like WordPress for creating an online discussion portal. Building an online community is not only beneficial to you but also to your readers who have lots of questions and doubts about your product.

For How2shout, first, we have started our forum on the free and open-source platform phpBB then we shifted to Vanilla forum software, and then finally stopped at the Question2Answer platform. Because we want something like Quora for our website where people just ask a question and get an answer from admin or community members. There are both best paid and free online Forum Platforms/Software available in the market but in this article, we are majorly going to discuss the free and open source

Here is a list of the best Open-source Forum Software/Platforms in 2022

phpBB

phpBB is the most popular best free and Open Source forum software that comes with an extensive database of user-created plugins and styles or themes. It is a free flat-forum bulletin board software that can customize easily according to user choice. There are also phpBB themes available online both paid and free.

The default interface does not seem too interactive like Discourse forum software but you can customize it by some developer to get better looks to suit your brand. The theming system is mediocre not like WordPress in terms of easy accessibility. Overall, if you talk about phpBB forums features and security then it is far better than free forums available. It has pretty much the same features as the paid Vbulletin which is around $250.
