Scheduling core

Booking infrastructure, on an open-source core.

Event types, availability, routing forms, webhooks and an embeddable booking widget. The assistant runs on top of this core.

Event types

Separate booking types by duration, location, buffer and price.

Availability schedules

Multiple working schedules, timezone handling, date-based exceptions.

Routing forms

Use the form builder to route each request to the right event type and person.

Embeddable widget

Embed the booking flow in your own site; API keys and webhooks are ready.

Out of office and travel

OOO entries and a travel schedule; slots shift while you are in another city.

Blocklist

Keep addresses you do not want out of your booking flow.

Booking audit log

Every change is recorded with who, when and through which channel.

Notifications

Email and WhatsApp notifications; reminder offsets are yours to set.
