HumHub

This open source social intranet and collaboration platform serves as a centralized digital workplace that connects people, enables seamless communication, facilitates knowledge sharing, and coordinates projects across departments and locations for organizations ranging from companies and municipalities to schools, nonprofits, clubs, associations, and educational institutions. It solves problems of information silos, scattered announcements, and inefficient collaboration by offering spaces for offices or projects, posts and news, file sharing, knowledge bases or wikis, calendars, surveys and polls, private messaging, and notifications, all configurable through a modular ecosystem of over 80 optional modules, with advanced permissions, full-text search, translation management, RESTful API, SSO/LDAP support, and a responsive design for on-premise or secure SaaS deployment, while remaining GDPR compliant and adaptable to multilingual environments.

HumHub can be found in Internal Communications Software categories.
