Discourse
Modern forum software for community discussion
Discourse is the 100% open-source discussion platform that powers thriving communities. With 43K+ GitHub stars, it modernizes the forum concept with real-time features, mobile-first design, and deep integrations. Battle-tested for over a decade by thousands of communities.

Why Discourse?
Traditional forums feel dated. Reddit and Discord don't give you ownership. Slack-style chat loses knowledge in endless scrolling. For building a lasting community with organized discussions, searchable knowledge, and engaged members, you need modern forum software that you own.
How It Works
Discourse provides a familiar topic-reply structure with modern UX improvements. Trust levels reward engaged members automatically. Real-time chat adds immediacy. Full-text search makes knowledge discoverable. Self-host for complete control or use official hosting.
What Is Discourse?
Discourse is an open-source discussion platform. It provides topic-based discussions, real-time chat, trust levels, categories, tags, and extensive customization. Ruby on Rails backend with Ember.js frontend.
