I build Tymeslot as an open-source calendar and scheduling tool. I wanted it to be beautiful and branded. Now I am proud to say that it has regular contributions and is used by so many people in the cloud and on their servers. Please try it out and if you like it, get in touch on Github or the web!

Share one link, people book a free slot, and Tymeslot checks your calendars and adds the video link. Open source under the GNU AGPLv3. Self-host the full feature set for free with Docker, Cloudron or Railway, so every booking, calendar token and client detail stays on infrastructure you control. Built in Elixir and Phoenix. Connect Google, Outlook, Exchange, iCloud or any CalDAV server, including Nextcloud, Radicale and Baikal. Tymeslot checks them all before it offers a slot, so nobody can book over an existing appointment. Tymeslot creates the meeting link when someone books, with Zoom, Google Meet, Teams, MiroTalk P2P and more. Booking pages carry no third-party trackers and embed on any site. Developed in the open for ten months, with code from 10 contributors. Prefer not to run a server? The cloud is free to start, and Pro (€9/month flat) adds automation, booking analytics and payments.

Tymeslot FAQ

Is self-hosting really free?+

Yes. The entire product is open source under GNU AGPLv3 and can be run on your own server with Docker at no cost.

What’s the difference between Cloud Free and Cloud Pro?+

Cloud Free provides all integrations and unlimited bookings with a small Tymeslot footer; Cloud Pro adds automation, group bookings, analytics, payments and removes branding.

Can I cancel anytime?+

Yes. There are no contracts; you can cancel from your dashboard and keep Pro features until the paid period ends.

Do I need a credit card to start?+

No credit card is required for Cloud Free; the Pro plan offers a 7-day free trial and only charges after you confirm.
