Forem

With 22,700 GitHub stars, 4,100+ forks, and proven scale powering dev.to — one of the largest developer communities serving millions of monthly users — Forem provides a complete community platform for building engaged audiences around shared interests, whether for developer documentation, customer communities, fan bases, or professional networks. The Rails backend with Preact frontend delivers article publishing with a rich Markdown editor, threaded discussions, user profiles with portfolio links, tag-based content organization, podcast hosting, classified listings for jobs and events, and social interactions including reactions, bookmarks, and following. AI-powered semantic search using PostgreSQL pgvector embeddings surfaces relevant content across articles and concepts, while scheduled automations enable community bots to create automated roundups, republish curated content, and trigger time-based moderation actions. Score-based content ranking replaces simple reaction counts with nuanced algorithms that resist gaming. The admin dashboard provides user management, content moderation, community settings, analytics, and organization controls. OAuth integration supports GitHub, Twitter, Apple, and configurable OIDC providers for frictionless sign-up. Dynamic open-graph image generation creates branded social cards automatically. Deploy with Kamal 2 to any cloud provider or bare metal server with PostgreSQL and Redis. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.
