What is Kliv?
Kliv isn’t a generic booking calendar you sign up for and configure — it’s an AI app builder that builds software for you.
You describe the app you need in plain words, and Kliv builds it: the data, the logic, the screens, and the workflows. You own the result, run it on your own domain and accounts, and change it later by asking for changes. It isn’t a template with your name on it.
On this page, that app is an onsen booking system. Kliv builds all kinds of web apps; this is one example.
Why build your own onsen booking system?
An onsen ryokan booking system has more to track than rooms. It may need dinner counts, allergies, private bath slots, day-bather caps, seasonal prices, pickup times, and pages in more than one language. Generic calendars often treat those as notes.
Kliv builds the booking system around the house. Rooms, plans, baths, dinners, tickets, schedules, prices, and guest messages all read from the same records.
What the booking system keeps
The records a generic calendar usually misses.
Rooms and plans
Each room has capacity, layout, and plan details such as dinner included or not. A booking that breaks capacity rules can be refused.
Private bath calendar
The rotenburo can sell 45-minute slots, with each slot held by one room at a time.
Dinner counts and allergies
Each booking carries kaiseki count, child portions, and allergies, so the kitchen works from booking records.
Day bathers
Day-visit tickets can sell separately from rooms, capped by hour, and stop selling when an hour is full.
Season rates
Crab season, Golden Week, and quiet weeks can be dated price windows in the catalog.
An example: Fumie’s seven-room ryokan
Here’s how one ryokan might use it. It’s only an example — you would describe your own rooms, plans, bath rules, languages, and seasonal prices.
A guest books in English
A couple in Melbourne books the corner room for ¥42,900 a night with dinner, chooses the 9 p.m. bath slot, and notes one shellfish allergy.
The staff sees the same booking in Japanese
Fumie’s admin shows the reservation details in Japanese, while the guest confirmation uses the language they booked in.
The kitchen list sends itself
Each morning, a scheduled email lists tonight’s arrivals, covers, child portions, and allergies.
Bath slots do not double-book
The private bath changes hands every 45 minutes. The 9 p.m. slot belongs to the corner room because the slot record is already held.
Checkout follows the booking
Room, dinners, and extra sake become the receipt, and the room joins the cleaning list before the guests leave for the train.
Describe the booking system you want
Kliv builds from your description, so include rooms, rates, meal plans, bath rules, caps, languages, and messages. Here are three examples:
Hot-spring inn
Rooms, dinner plans, and station pickups.
“Build an onsen booking system for a ten-room hot-spring inn. Include dinner and breakfast plans, station pickup times collected at booking, allergy notes sent to the kitchen, private bath slots in 45-minute blocks, and Japanese and English guest pages.”
Day-visit spa
Hourly tickets with caps.
“Build a day-visit booking site for our bathhouse. Sell hourly bath tickets capped at 20 people per hour, towel rental add-ons for ¥500, quiet-hours tickets after 7 p.m., and confirmation emails in Japanese and English.”
Mountain guesthouse
Rooms, shared bath slots, and seasonal prices.
“Build a guesthouse booking system with four rooms, shared bath time slots, breakfast counts for the kitchen, allergy notes, and seasonal prices that change automatically on Golden Week and winter dates.”
How it comes together
One slot belongs to one party. A bath slot is a record that can be held once. A second booking cannot take the same time.
Prices have dates. Crab season can be a dated window in the catalog, so guests booking January dates are charged the January rate even if they book earlier.
Two languages share one record. Kliv apps ship in 23 locales, with Japanese and English among the fully finished ones. Guests and staff can read the same booking in different languages.
Daily lists run on schedules. Kitchen lists, bath rotas, and pickup emails can send on the house’s templates.
A local booking system can be very specific. The local-business page shows the same pattern for other local businesses.
Common questions
What exactly is Kliv?
Kliv is an AI app builder. You describe your onsen booking system, and it builds a real app for rooms, plans, bath slots, rates, messages, and admin.
Do I get a real app, or a template?
A real app. Rooms, bookings, bath slots, meal counts, allergies, tickets, and price windows are structured records.
Can I change it after it’s built?
Yes. You can ask for new room plans, changed bath hours, new rate windows, or different guest messages later.
Can guests book the private bath before they arrive?
Yes. The slot picker can be part of booking, and guests can also add a slot later from their reservation page if you allow it.
Do overseas guests get English pages?
Yes. The booking flow can run in English and Japanese while the admin remains Japanese.
Can we sell day-visit baths without rooms?
Yes. Hourly tickets with caps can live in the same catalog as room plans.
How do crab-season prices work?
They are dated price windows on room plans. The rate applies based on the stay dates, not when someone remembered to edit a page.
Do guests need their own Stripe accounts?
No. Guests pay by card if you take payment online. Stripe processes payments into your account.
Can I use my own domain?
Yes. The booking system can run on your own domain.
Can kitchen lists send automatically?
Yes. Scheduled emails can send covers, allergies, child portions, and arrivals to the right people.
Can I move off Kliv later?
Yes. The code syncs to your own Git repository, so leaving is a git pull, not a rebuild.
