Pros & Cons
tidycal
Pros
Genuinely free-forever plan with unlimited bookings and booking types, not just a trial.
Sells one-time "lifetime" plans ($29 Individual, $79 Agency) as an alternative to a recurring subscription.
Auto-generates Zoom, Google Meet, and Microsoft Teams links for booked meetings from the Individual Lifetime tier up.
Recognized as a #1 Product of the Day on Product Hunt, per a badge shown on the homepage.
Cons
Removing TidyCal branding and using a custom domain requires the separate Pro subscription ($12/mo, or $99/yr billed annually) on top of a lifetime purchase.
SMS reminders are limited to the US & Canada, per the Agency Lifetime plan description.
The AI booking assistant and group bookings aren't available on the free plan — they start at the paid Individual Lifetime tier.
DAViCal
Pros
Completely free and open source under the GPLv2 license
Full control and ownership over calendar and contact data via self-hosting
Implements open CalDAV/CardDAV standards, ensuring broad client compatibility
Mature, long-standing project with a stable feature set for group calendaring
Cons
Requires manual setup and maintenance of a PHP and PostgreSQL server stack
Administrative interface is functional but visually dated compared to newer alternatives
No official commercial support channel; relies on community and third-party providers
Less actively developed than some newer self-hosted alternatives like Baikal or Nextcloud
