Self-hosted appointment scheduler with Google Calendar sync
A customizable web application for booking appointments with service providers, featuring Google Calendar integration, email notifications, and multi-language support for self-hosted deployment.
Easy!Appointments is a web-based appointment scheduling platform designed for businesses that need complete control over their booking infrastructure. Built with PHP and MySQL, it installs on your own server and integrates seamlessly into existing websites without disrupting your current setup.
The platform handles the full appointment lifecycle: customers book through a sophisticated web interface, providers manage their schedules with customizable working plans and booking rules, and administrators oversee services, staff, and business logic. Two-way Google Calendar synchronization ensures your appointments stay current across all tools, while automated email notifications keep everyone informed.
Service-based businesses—from medical practices and salons to consulting firms and repair shops—benefit from Easy!Appointments' flexibility. The system adapts to complex workflows with support for multiple providers, service categories, and booking constraints. A translated interface serves international audiences, and the self-hosted architecture means you retain full ownership of customer data and booking history. Requires PHP 8.2+, MySQL, and basic server administration knowledge for deployment.
When teams consider Easy!Appointments, these hosted platforms usually appear on the same shortlist.
