Scheduling application for small teams
Create a booking page, connect Google Calendar to avoid double-booking, or use the same scheduling engine through the API.

One product, two ways to use it
Set the hours each Host can accept bookings, connect Google Calendar, and share the URL. Guests pick a time, confirm, and get a link that lets them reschedule or cancel later — no signup, no password.
Read available slots, create a booking, and receive a signed webhook when it commits. Add scheduling to a product you already have instead of rebuilding availability, conflict handling, and calendar sync.

}The booking is confirmed in the same response that reports the calendar event as pending. The guest is never left waiting on Google.
How it works
Give each Host weekly hours in their own timezone, then add date overrides for holidays and time off.

When a Host chooses to connect Google Calendar, Slotkit lists available calendars, checks selected calendars’ free/busy time so busy periods are not bookable, and creates or updates the Slotkit booking event in the chosen destination Calendar.
Publish the event type to get a booking URL, or issue an API key and drive the same event type from your own product.
slotkit.app/northwind/discovery-call
or
GET /v1/event-types/evt_…/slots
The booking is confirmed immediately. Calendar events, Meet links, and webhooks follow without holding up the guest.

What you get
No CRM, no analytics dashboard, no workflow builder, no payment collection. Slotkit stays a scheduling system so the scheduling stays predictable.
Weekly rules, date overrides, and time blocks decide when a Host can be booked. Connected Google Calendars remove selected calendars’ busy time before a slot is ever offered, and every slot is revalidated at the moment the guest confirms. Slotkit does not copy external Calendar events into its own booking records.

Reliability
Most scheduling breaks at the seams — the calendar write fails, the webhook times out, a retry lands twice. Slotkit commits the booking first and lets the rest recover around it.

Manage booking
We hold ourselves to internal operating targets for API availability and booking confirmation latency. Those are objectives we run against, not a contractual SLA. See our terms for what is and is not guaranteed, and security for how the credential boundaries work.
Slotkit is built to reach a sufficient feature set and then move to maintenance. A subscription sells continued development, and we would rather not sell you a roadmap we do not intend to have.
Slotkit is not currently billed. There is no checkout, no balance, no invoice, and no refund process. When this model is accepted and implemented, it will be announced with terms before anything is charged.
See the planned modelOne credit is one confirmed booking
The unit is a booking that actually happened, not a seat, a connected calendar, or a monthly platform tier. A Host who takes four bookings in a quiet month would use four credits.

Questions
One confirmed booking — the moment a booking is committed and the guest is told it is confirmed. Browsing available times, failed validation, CAPTCHA and email verification, and booking attempts that do not commit are not bookings.
No. Rescheduling moves the existing booking and keeps its identity and history. A cancellation followed by a brand new booking is a new booking.
The guest still gets a confirmed booking. Its calendar state shows as pending and reconciliation retries in the background. The booking is never rolled back because the calendar write is late.
Yes. Guided setup takes you from an empty workspace to a shareable booking page without writing any code.
Yes. The same event types and availability are readable and bookable server to server with a scoped API key, whether or not you ever share the hosted page.
Google Calendar, including Google Meet links. Microsoft, Outlook, Zoom, and Apple Calendar are not supported.
No, and not by omission. Slotkit is built to reach a sufficient feature set and then move to maintenance, and a subscription sells continued development we do not intend to promise. The planned model is prepaid confirmed bookings. Nothing is purchasable yet.
The proposal is 24 months, with any new purchase extending the whole remaining balance. It is proposed rather than decided — credit expiry has to clear legal review first, and the pricing page says so.
Start with an email address. Guided setup walks through availability, calendar, and your first event type.
