LobbyStack

LobbyStack released version v1.0.0, an MIT-licensed, self-hostable AI receptionist that answers business calls, books appointments through Google Calendar, Cal.com or Calendly, and texts callers confirmations, aimed at small businesses that lose work to missed calls. The repository has 52 stars and its last commit was 16 hours ago, 8 months after the project began; the tool imports website content and PDF, Word and text files for its knowledge base, transfers urgent calls to a set number with the caller's reason and contact details, supports 70+ languages, and includes Zapier, webhook and MCP integrations on every plan. A free 14-day plan includes 30 voice minutes, with paid plans adding a dedicated number and more minutes, positioning LobbyStack as a self-hostable alternative to hosted AI receptionists such as Reception.ai.

It's built for small businesses that lose work to missed calls, from trades to service shops. You can let it answer every call, or only step in when your team is busy or closed. It handles several calls at once. - Appointment booking: connects to Google Calendar, Cal.com https://openalternative.co/cal-com or Calendly, checks availability, offers open times, and texts the caller a confirmation. - Knowledge from your content: import your website, upload PDFs, Word and text files, and add services, hours and policies in the dashboard. - Human handoff: urgent or unusual calls transfer to a number you set, with the caller's reason and contact details attached. - Messages: when no one is available, it collects names, contact info, service needs and timing, then emails your team. - Call review: recordings, transcripts, summaries and bookings sit in one dashboard instead of scattered voicemails. - Languages: callers can speak 70+ languages, and you set the greeting, tone and call rules. Setup is short. Connect a new local number or forward your existing one, add your knowledge, set the rules, and go live. Zapier, webhook and MCP integrations are included on every plan. The code is open source. You can use the hosted cloud version or self-host to keep call recordings and customer data on your own infrastructure. A free 14-day plan includes 30 voice minutes, and paid plans add a dedicated number and more minutes. It's a self-hostable option for businesses comparing hosted AI receptionists like Reception.ai https://openalternative.co/alternatives/reception-ai .
