Forem

Forem is an open-source software platform for building online communities and discussion sites. It provides the underlying technology for community-driven spaces that emphasize user-generated content, discussions, and collaboration. The most well-known site powered by Forem is dev.to, a large developer community, but the software is also used by other communities hosted on Forem.

Forem offers features common to modern community platforms, including publishing workflows for posts, tutorials, and articles; threaded discussions and comments; tagging and topic discovery; user profiles and personal feeds; search and content discovery; notifications; and moderation tools with roles and permissions. It is designed to support community governance, privacy controls, and site customization. The platform also exposes APIs and integration points to allow external tools and services to interact with content and user data.

The project is open source and maintained by Forem, the organization behind the software, with contributions from a community of developers. Its codebase is publicly available on GitHub, inviting collaboration through issues and pull requests. Forem emphasizes extensibility and community ownership, aiming to enable independent groups to host their own branded online communities using a shared, adaptable platform.
