An internet forum application is a discussion platform where individuals hold conversations in the form of posted messages. This type of software is a very powerful tool to run online communities, to disseminate information, share experiences and ideas, receive online support, interact with others learning new intercultural skills, and much more. Forums are online communities where people share thoughts, ideas and opinions. Organizations also use forums as a method of supporting their customers.
A forum can contain a number of subforums, each of which can have several topics. Within a forum’s topic, each new discussion started is called a thread.
There are two types of structure used in a discussion forum. The most commonly used is the flat message structure where it is only possible to add a message to the end of a thread. A threaded view structure is less commonly used, in part because it’s regarded as somewhat dated.
Messages are typically stored in a relational database such as MySQL, or PostgreSQL.
There is a good range of forum software that is released under an open source license. You may have heard of phpBB, one of the oldest and finest open source forum software. But there’s lots of good alternatives. Which is the best suited forum software largely depends on your requirements. For example, if you need a good Rails forum software, look no further than Discourse or Thredded. Alternatively, if you’re committed to WordPress, it may make sense to use bbPress.
The chart below captures our recommendations. All of the software featured here are free and open source goodness.
