A platform for community discussion. Free, open, simple.
Discourse is the online home for your community. We offer a 100% open source community platform to those who want complete control over how and where their site is run.
Our platform has been battle-tested for over a decade and continues to evolve to meet users’ needs for a powerful community platform. Discourse allows you to create discussion topics and connect using real-time chat, as well as access an ever-growing number of official and community themes. In addition, we offer a wide variety of plugins for features ranging from chatbots powered by Discourse AI to functionalities like SQL analysis using the Data Explorer plugin.
To get your environment set up, follow the community setup guide for your operating system.
If you're familiar with how Rails works and are comfortable setting up your own environment, you can also try out the Discourse Advanced Developer Guide, which is aimed primarily at Ubuntu and macOS environments.
