LobbyStack is an open-source AI receptionist platform for small businesses. It answers phone calls, books appointments, handles appointment changes, and transfers calls to a person when needed. It is built for clinics, salons, repair shops, local service companies, restaurants, and any business that loses revenue when nobody is available to answer the phone. LobbyStack gives teams a modern AI front desk that can be hosted in the cloud or self-hosted on their own infrastructure.
