Deep Dive: Switching from zcal to TidyCal Free
Trade-offs, installation & data architecture
What you trade away
TidyCal Free handles one-person booking links, but one connected calendar and no free group-meeting workflow make it a poor substitute for zcal's polls and multi-person scheduling.
How to deploy TidyCal Free
Hosted signup and one calendar connection
What it takes to run
There is no technical install hurdle, but free accounts get only one calendar connection and omit automatic video links, group meetings, custom emails, exports, analytics and API access.
Where your data lives
Booking types, attendee answers and booking records live in TidyCal's cloud and are synchronized to the connected calendar; the internal storage format is not disclosed.
Why fork TidyCal Free instead of vibe-coding a zcal clone?
zcal's solo core is compact: build a personal freeform scheduling tool that reads one calendar, publishes availability, reserves a slot, and writes the event back. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on OAuth, calendar reliability.
