# Thunderbird Appointment

> Thunderbird Appointment (554 stars, latest release Oct 2026) is the scheduling service behind appointment.tb.pro. Hosts set availability, connect CalDAV or Google calendars and share a booking page; Zoom links can be attached. MPL-2.0. Docker Compose is the only supported install (backend, frontend, PostgreSQL, Redis, mail). The README frames self-hosting mainly around development; the built-in password login is "meant for developing and testing". No group polls, team round-robin or payments are documented.
