Only times that are genuinely free
Opening hours, breaks, holidays, staff days off, service length and buffer time are combined into the only slots customers can pick.
Online booking for appointment-based businesses
The right moment,
booked.
Kairo gives your business its own booking page, a calendar that can’t double-book and a client list that keeps itself — so customers book in under a minute and you stop playing phone tag.

Double bookings can’t happen
Every booking locks its minutes in the database, so even simultaneous requests can’t overlap.

Two chairs, each barber with their own hours. Customers pick a barber or take whoever's free.

What a calmer calendar sounds like
Demo content — illustrative testimonials, not real customers“The phone used to ring all day. Now it's mostly people booking in themselves while I'm cutting.”
Sample Barber
Barbershop owner, 3 chairs
“Processing buffers were the thing. My colourists finally stopped running twenty minutes late.”
Sample Salon Manager
Hair & beauty salon
“I approve every request first — clients see exactly which times I really have.”
Sample Consultant
Independent advisor
No. Customers choose a service and a time, enter their name and email, and they're booked. They get a confirmation email with a private link to view, reschedule or cancel — no password required.
