A complete look at every feature - from calendar sync to Slack and Telegram notifications. No surprises. No lock-in.
Tymeslot reads availability across all your connected calendars simultaneously - a conflict anywhere blocks the slot everywhere.
Connect Google, Outlook, CalDAV, and Nextcloud - simultaneously. The moment a new event lands on any of them, that time window is blocked across all your booking types.
Padding before and after meetings, configurable per event type.
Different working hours for every day of the week.
Keep up to five named sets of hours - office hours, evenings, weekends - and give each meeting type its own.
Limit how far ahead guests can book, from 7 days to 6 months.
Slots inside your lead time are hidden automatically.
Guests book in their timezone, you see yours - DST included.
Day, week, or month - with drag-and-drop rescheduling.
Propose times, let the group vote, confirm the winner as a real meeting.
Hold a booking until you have agreed to it. The slot is reserved, the guest knows it is a request, and only your answer confirms it.
Connect your calendars, pick a video tool, and you're done.
Connect as many accounts as you like - free/busy is read across all of them at once.
A video room is generated on every confirmed booking and included in the confirmation email and calendar invite.
Charge attendees at booking time - the money lands directly in your Stripe account.
Turn on payments for any event type and set a price. Attendees pay through Stripe before the slot is confirmed - no payment, no booking.
Funds go straight to your bank. We never touch the money.
13 currencies - EUR, USD, GBP, CHF, and more.
Emailed to every paid attendee.
Full or partial, straight from the dashboard.
Cancel a paid booking and refund it in one step.

A booking page looks like a form over a calendar. The hard part is that every calendar system disagrees about which events actually make you busy, and once we got that answer in two places, the two places disagreed too.
