Discourse is the 100% open source discussion platform built for the next decade of the Internet. It works as:
- a mailing list
- a discussion forum
- a long-form chat room
To learn more about the philosophy and goals of the project, visit discourse.org.

If you're brand new to Ruby and Rails, please see Discourse as Your First Rails App or our Discourse Vagrant Developer Guide, which includes a development environment in a virtual machine.
-
If you're familiar with how Rails works and are comfortable setting up your own environment, use our Discourse Advanced Developer Guide.
Before you get started, ensure you have the following minimum versions: Ruby 2.0.0+, PostgreSQL 9.3+, Redis 2.6+. If you're having trouble, please see our TROUBLESHOOTING GUIDE first!
If you want to set up a Discourse forum for production use, see our Discourse Install Guide.
If you're looking for business class hosting, see discourse.org/buy.
Discourse is built for the next 10 years of the Internet, so our requirements are high:
| Browsers | Tablets | Smartphones |
|---|---|---|
| Safari 5.1+ | iPad 2+ | iOS 6+ |
| Google Chrome 23+ | Android 4.1+ | Android 4.1+ |
| Internet Explorer 10+ | Windows 8 | Windows Phone 8 |
| Firefox 16+ |
Internet Explorer 9.0 is technically supported, but it is our absolute minimum spec browser and may not be fully functional.
- Ruby on Rails — Our back end API is a Rails app. It responds to requests RESTfully in JSON.
- Ember.js — Our front end is an Ember.js app that communicates with the Rails API.
- PostgreSQL — Our main data store is in Postgres.
- Redis — We use Redis as a cache and for transient data.
Plus lots of Ruby Gems, a complete list of which is at /master/Gemfile.
