Every feature in one place, from calendar sync and paid bookings to Slack and Telegram alerts. The code is open source, so you can always run it yourself.
Tymeslot checks every calendar you connect, and an event in any calendar you set to block takes that slot off your booking page.
Connect Google, Outlook, Exchange and any CalDAV server side by side, and choose which ones block your time. When an event lands in one of those, Tymeslot blocks that time across every meeting type you offer, and each new booking is written back to the calendar you choose.
Separate buffers before and after meetings, set per availability schedule.
Different working hours for every day of the week, including hours that run past midnight.
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 one day up to a year.
Set a lead time of up to a week. Slots inside it are hidden, so nobody books you for ten minutes from now.
Guests book in their timezone and you see yours, with daylight saving handled on both sides.
Day, three-day, week, month or agenda view. Drag a meeting to a new slot to reschedule it.
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.
In person, phone, video or somewhere else. Offer several and the guest picks one as they book, down to the video service.
Setup guide →Let several guests book the same slot, up to a limit you set, for classes, workshops and group calls.
Connect your calendars, pick a video tool, and you're done.
Connect as many accounts as you like, and busy time in them blocks your availability unless you set a calendar to show only. Read-only calendar subscriptions (a feed URL) can block too.
Offer one service or several and let the guest choose. The room is created on confirmation and included in the confirmation email and calendar invite.
Charge clients when they book, and the money lands in your own Stripe account. Payments are part of Pro on tymeslot.app and free when you self-host.
Turn on payments for any meeting 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, including EUR, USD, GBP and CHF.
Emailed to every paid attendee.
Full or partial, straight from the dashboard.
Cancel a paid booking and refund it in one step.
Rescheduling never triggers a second charge.
Every booking event can fire a webhook or ping you in Slack or Telegram as it happens. Automation is part of Pro on tymeslot.app and free when you self-host.

How Tymeslot fits the way each profession books, with a recommended setup and a comparison of the usual tools.
A booking page looks like a form over a calendar. The hard part is that every calendar system disagrees about which events make you busy, and once my code answered that question in two places, the two answers disagreed too.
