LobbyStack
What is LobbyStack?
LobbyStack is an open-source AI receptionist that answers the phone for small businesses that run on calls: plumbers, HVAC crews, dental offices, salons and property managers. You choose whether it takes every call or only the ones your team misses after hours and at peak times. Callers book, move or cancel an appointment before they hang up. If your team already works in Google Calendar, Cal.com or Calendly, connect it and new bookings show up there. Callers can ask about prices or check whether you serve their area, and LobbyStack answers from your website, PDFs and FAQs. It transfers urgent calls to the right person. When nobody picks up, it takes a message and sends you a summary with the transcript. You write the rules in plain language, like "send burst-pipe calls to Mike", instead of drawing call flows. Calls run on OpenAI GPT-Live, supports 70+ languages and can switch languages mid call. Keep your current number with call forwarding, or get a local number in the US, Canada, the UK or Australia. Developers get a REST API, webhooks, Zapier and an MCP server, so Claude or ChatGPT can read your calls and book appointments. The code is MIT-licensed, and you can host it yourself.
How to use LobbyStack?
