Real-time availability, recurring schedules, and bookings. Take our widget, as a React component or one <script> tag, or build your own UI on the same API. No calendar to build, and no double bookings to worry about.
Not every business runs a fixed Monday to Friday week. Créno doesn't assume yours does.
Set hours using weekly, bi-weekly, or "3rd Tuesday of the month" patterns that actually match how your business runs, and change them going forward without losing history.
One resource for a solo operator, or a dozen for a team: every bay, stylist, or room gets its own independent calendar.
Offer one simple booking flow, or a full menu of services with their own durations and schedules. Customers only see a picker when there's something to pick.
Booking conflicts are prevented at the database level, not just in the UI, and verified under real concurrent load, not just in theory.
Let bookings confirm instantly, or review and approve each one yourself. Configurable per calendar.
Every color, radius, and font is a CSS variable. Theme it to disappear into your site, with no Créno branding required.
Take our widget and write almost nothing: a React or Vue component, or one script tag anywhere else. Or keep control of the UI and call the same API from your server, with our Node.js and Python kits.
