Open source community platform for forums, real-time chat and discussion, aimed at organizations that want to run their own site.

Discourse is a community platform for organizations that want complete control over how and where their site runs. It has been in production for over a decade, and self-hosting removes the dependence on a forum vendor deciding pricing, data location and feature direction.
The backend is a Ruby on Rails application answering RESTfully in JSON, and the frontend is an Ember.js app talking to that API. PostgreSQL holds the main data store while Redis serves as cache and transient storage.
The platform gives community managers several distinct surfaces to work with.
- Discussion topics: the core format, built for conversations that stay readable over time.
- Real-time chat: a built in channel alongside threaded discussion.
- Themes: an ever growing set of official and community themes for changing how a site looks.
- Plugins: extend the site with tools such as Discourse AI chatbots and SQL analysis through Data Explorer.
Running it in production needs Ruby 3.4 or later, PostgreSQL 15 and Redis 7, with an install guide in the repository and development setups documented for Docker, macOS, Ubuntu, Debian and Windows. The latest stable releases of Safari, Chrome, Edge and Firefox are supported, along with iOS and Android. Official hosting exists for teams that prefer to skip server maintenance entirely.
A self-hosted course platform for teachers and training teams, covering authoring, assignments, discussion and certificates in a single instance.

LearnHouse is a platform for building and running educational content, from one instructor publishing a course to an organization training its staff. It puts authoring, delivery, discussion and assessment in a single instance instead of stitching a course tool to a forum to a video host.
The codebase splits into four applications. A Next.js and React frontend carries the dashboard, course player and Notion style block editor built on Tiptap; a FastAPI backend in Python handles auth, courses, payments, AI and analytics; a Hocuspocus and Yjs server syncs live collaboration; and an official CLI manages instances. PostgreSQL and Redis sit underneath, with S3 for files.
Teaching features reach past text and video.
- Code: real code execution with auto-grading in more than 30 languages.
- Playgrounds: AI generated interactive elements, simulations and diagrams.
- Boards: whiteboards several people edit at the same time.
- Assignments: set tasks, track submissions and issue certificates on completion.
- Podcasts: publish audio for learners who are not at a desk.
- Analytics: follow engagement and course performance across an organization.
Self-hosting starts with one npx command that opens a setup wizard for domain, database, admin account and optional features, then writes the config and starts the services. The same CLI streams logs, takes backups, applies updates and diagnoses problems. The core is AGPL-3.0, while payments, single sign-on and running multiple organizations from one instance sit under a separate enterprise license.
