I’ve assembled a list of the top open source Q&A platforms that are currently available. The list contains only projects which are in active development and have a working demo site. There are a few similar blog posts out there but they’re quite outdated. Most of the projects listed below are inspired by Stack Overflow which is in fact the most popular community for questions and answers related to programming. Please, bear in mind that the list is not ordered in any way.
Have you ever wanted to have a Q&A section on your website with the functionality of Stack Overflow? Well, this one is for you! Scoold is a cloud-ready Stack Overflow clone, powered by our Para backend. It’s a real-world application, showcasing the Para technology and how it can be utilized to get a project off the ground quickly. Scoold is a lightweight (~4000 LOC) web application written in Java – it runs great on the smallest Heroku dyno and doesn’t require a database.
