Summary
NexCal is a free, self-hosted appointment scheduling platform for teams with multiple service providers, including clinics, salons, consulting firms, and studios. Customers book by choosing a practitioner, service, and time slot. Teams can manage staff calendars with OWNER and STAFF roles, while patients can review booking and payment details, use invoices and meeting links, and reschedule or cancel up to 24 hours before an appointment. Payments use a Midtrans plugin and can be configured for full payment or service-specific down payments; payment features can be disabled when keys are absent. Confirmed appointments can receive automatically generated Google Meet links. Its dashboard tracks revenue, 30-day trends, service popularity, staff performance, and operational measures. NexCal also supports WhatsApp through MultiWA and Google Calendar. Data is hosted on the user's server, with organizations isolated by default. The project is MIT-licensed and free forever, but production deployment requires Docker and Docker Compose. Recurring bookings, multilingual support, a progressive web app, and shared multi-tenant SaaS are future features.
