Concerto

Concerto is an open-source digital signage project used widely by schools and nonprofits. Administrators post announcements, photos, or videos through a web-based dashboard, then displays update in real time. Its modular interface can show weather, RSS feeds, or custom text tickers. Multi-user permission levels let different departments contribute content. Concerto’s volunteer-driven ecosystem suits communities or campuses seeking a free, customizable platform requiring moderate tech setup.
