Creno

Créno lets clients book a service, choose a provider and pick an available
time slot directly from your WordPress site — no third-party SaaS, no
recurring subscription.

Client side
* Choose a service, a provider, and a duration
* Pick a time slot from a real-time availability calendar
* Get a confirmation page with a private link to manage the request
* Modify or cancel the request at any time (no account); modifications go back to pending for salon re-confirmation
* Phone number is optional
* Front end talks to the plugin via the WordPress REST API (creno/v1)

Admin side
* Calendar view of pending and confirmed bookings
* Confirm, refuse, modify, or cancel bookings
* Create manual bookings with relaxed rules (external provider, free-text service)
* Configure services, durations, and provider working hours
* Dedicated notification email for the salon inbox
* Customize page titles, URL slugs, and accent colors
* Front booking pages are created when at least one service and one provider with hours exist
