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.
Baïkal
Pros
Free and open source under the GPL v3 license
Lightweight with minimal server requirements
Broad compatibility with major calendar and contacts clients
Simple installation via web installer or Docker
Cons
Minimal feature set compared to full groupware suites
Development pace has slowed with less frequent releases
Requires self-hosting and manual server maintenance
