Deep Dive: Switching from zcal to TidyCal Free

Trade-offs, installation & data architecture

The Catch vs zcal

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.

Installation

How to deploy TidyCal Free

Hosted signup and one calendar connection

Day-2 Operations & Setup

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.

Data Ownership

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.

Build vs Fork Verdict: YES (the core loop fits in a weekend)

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.
