Tymeslot is an open-source (AGPL-3), privacy-first alternative to Calendly and Cal.com. Share one booking link: Tymeslot checks every connected calendar, creates the video link and sends the confirmations. No third-party trackers on booking pages. Self-host it for free with the full feature set, or use the managed cloud, hosted in Germany, with Pro at €9/mo.

What to expect from an ideal product
- Tymeslot connects all your calendars at once, so invitees only see slots that are actually free, no manual blocking or double-bookings.
- The booking page runs zero third-party trackers, making it a direct swap for Calendly if GDPR compliance or client privacy is a hard requirement.
- Self-hosting is free with the full feature set intact, no paywalled features, no usage caps, just deploy and own your data.
- Video links are generated and confirmation emails are sent automatically the moment someone books, no Zapier glue required.
- The managed cloud runs on servers in Germany at 9 euros per month, which matters if you need to tell clients exactly where their data lives.
