## Introduction
Forem is the open-source Rails application that powers DEV.to, one of the largest developer communities on the web. It provides a full-featured platform for publishing articles, hosting discussions, sharing podcasts, and building engaged communities around any topic.

## What Forem Does
- Publishes long-form articles with Markdown, code snippets, and liquid tags
- Hosts threaded discussions, comments, and community Q&A
- Manages user profiles with follow systems, badges, and reading lists
- Distributes podcasts with built-in audio player and episode management
- Supports listings for jobs, events, and community classifieds

## Architecture Overview
Forem is a Ruby on Rails monolith backed by PostgreSQL for data, Redis for caching and background jobs, and Elasticsearch for search. The frontend combines server-rendered HTML with Preact components for interactive features. Sidekiq processes background tasks like notifications, feed generation, and content moderation. Images and media are stored via Active Storage with cloud provider adapters.

## Self-Hosting & Configuration
- Requires Ruby 3.1+, Node.js 18+, PostgreSQL 13+, Redis 6+, and Elasticsearch 7
- Configure environment variables for database, Redis, email (SMTP), and cloud storage
- Use Forem's setup scripts or Docker for development and staging environments
- Set up an Imgproxy instance for dynamic image resizing and CDN delivery
- Run Sidekiq workers alongside the web process for background job processing

## Key Features
- Built-in content moderation tools with user roles and tag management
- Customizable branding, colors, and navigation for white-label communities
- SEO-optimized article pages with Open Graph metadata and structured data
- Connect and API endpoints for third-party integrations and mobile apps
- Federated features via ActivityPub for cross-community interaction

## Comparison with Similar Tools
- **Discourse** — Focused on threaded forum discussion; less article publishing capability
- **Ghost** — Polished publishing platform for newsletters and blogs; lacks community interaction depth
- **WordPress** — Versatile CMS with plugins for forums; heavier and requires more customization
- **Hashnode** — Developer blogging platform; hosted-only with limited self-hosting options
- **Lemmy** — Federated link aggregator; focused on link sharing rather than long-form content

## FAQ
