Build a multilingual social network with PHP-powered flexibility
OSSN lets you launch a fully featured, multilingual social networking site with user profiles, groups, live chat, photo albums, and admin dashboard—all powered by PHP and extensible components.

OSSN is a PHP‑based social networking engine designed for communities, clubs, and organizations that want to host their own platform. It offers user registration, profiles, friends, groups, blogs, and a real‑time chat system, all wrapped in a mobile‑responsive interface.
The platform ships with more than 20 language packs, a Progressive Web App, and integrations such as Giphy, emojis, and video embedding. Administrators control the site through a dashboard that includes user analytics, ads management, component configuration, and theme handling. Extensibility is provided via a component system and a WebServices API, allowing developers to add custom pages, menus, or third‑party services.
OSSN can be installed through a web installer, Docker image, pre‑built VM, or Ubuntu apt repository. The target directory must be writable by the web server, and a standard LAMP stack (Apache, MySQL, PHP) is recommended. Detailed setup instructions are available on the official website.
When teams consider OSSN, these hosted platforms usually appear on the same shortlist.
