HumHub — Open-Source Enterprise Social Network

Introduction

HumHub is an open-source social networking platform designed for organizations that want to run their own private community or intranet. Built on the Yii2 PHP framework, it provides a familiar social-media-like experience with activity streams, spaces, messaging, and a module marketplace for extending functionality.

What HumHub Does

• Creates a private social network with user profiles, activity streams, and notifications
• Organizes content into Spaces (groups) with separate membership and permissions
• Provides direct messaging, file sharing, and collaborative content creation
• Supports a marketplace of modules for calendars, wikis, tasks, and polls
• Enables SSO integration with LDAP, SAML, and OAuth providers

Architecture Overview

HumHub is built on the Yii2 PHP framework using an MVC architecture. User content is stored in MySQL or MariaDB. The module system allows installing marketplace modules or building custom ones that hook into the core via events and widgets. The frontend uses a responsive Bootstrap-based theme with JavaScript enhancements. Real-time updates use long-polling or WebSocket via an optional push server.

• Install via Composer or download the release archive
• Run the web-based setup wizard to configure database and admin account
• Configure LDAP or SAML for enterprise single sign-on
• Use the admin panel to manage modules, themes, and user registration settings
