Open scheduling infrastructure

Meetings booked at times you’re actually free.

Kaigi turns your real calendar into a booking page. Set your event types and weekly hours, sync Google Calendar so guests only see slots that are truly open, and let every booking send its own confirmation and calendar invite.

Invite sent to both calendars

The whole booking, handled

From a shared link to a confirmed invite, without the email ping-pong.

Public booking pages

Every account gets a shareable page. Guests pick a time that works; you stay out of the back-and-forth entirely.

Google Calendar

Kaigi reads your free/busy to hide conflicts, then writes the event back the moment someone books.

Availability, your way

Weekly hours plus date-specific overrides for the days that break the pattern. Time zones resolved for every guest.

Event types & buffers

Run as many meeting types as you need — each with its own duration and buffers, so back-to-backs never collide.

Round-robin for teams

Share one link across a team and Kaigi distributes incoming bookings round-robin to whoever is free.

Confirmations that carry the invite

The instant a booking lands, both sides get a confirmation email with a real calendar invite attached — no extra step, no reminder app to wire up.

How it works

Three steps to booked.

01
Publish your link
Define your event types and weekly hours, connect Google Calendar, and share your page. Setup takes minutes, not an afternoon.
02
Guests pick a real opening
Kaigi checks your live free/busy in the background, so the only times a guest can choose are times that are genuinely open.
03
Everyone gets the invite
A confirmation email and calendar invite go out the moment it's booked. The event lands on both calendars, ready to go.

Built API-first

A booking API you can build on.

Every calendar in Kaigi is reachable over HTTP. Take bookings straight from your own product — no scraping, no undocumented endpoints.

REST API at /api/v1, authenticated with scoped API keys
A public booking API you can call from your own front ends
