People still pay for TidyCal because people pay because one double booking or missed invite can cost more than years of subscription fees. The recurring cost buys OAuth refresh, webhooks, timezone databases, race conditions, reminders, deliverability, privacy, and uptime, not just the visible interface.
Questions about these alternatives
Is there a free alternative to TidyCal?
Yes: Cal.com Free, Calendly Free, Google Calendar appointment schedules and 3 more. These are recorded free or open-source options. Compare their feature limits, licenses, hosting costs and current availability before choosing.
Should I just build my own TidyCal?
Our verdict is KINDA. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For TidyCal, publish simple booking pages connected to one calendar and send confirmations. The hard boundary is lifetime hosted service, calendar integrations, and extremely low maintenance cost, plus calendar integrations and reliability. Review the scope, implementation prompt and trade-offs in the TidyCal build guide.
