Online appointment booking from Switzerland
Tymeslot self-hosted in Geneva – the sovereign alternative to Calendly. Your clients book appointments themselves online, and you save the email back-and-forth. FADP-compliant, in your branding and on your domain.
What is Tymeslot?
Tymeslot is an appointment booking tool. Instead of searching for a time by email back and forth, your clients get their own booking page: they see your free times and pick a slot that suits them. The appointment lands in your calendar automatically – including confirmation and reminder.
A client books an intro call → picks a free slot from your calendar and instantly receives a confirmation with a video link.
A client in another time zone → selects their time zone and sees the free slots in their local time.
Before the appointment → Tymeslot automatically sends a reminder to the client, at a time you choose.
At vant.ch, Tymeslot runs self-hosted on Swiss servers in Geneva. Unlike Calendly, bookings and customer data stay on your own infrastructure, under Swiss data protection. Tymeslot is open source (AGPL-3.0 licence).
