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.
Is there a free alternative to TidyCal?
Yes: Cal.com Free, Calendly Free, Google Calendar appointment schedules and 3 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own TidyCal?
Our verdict is PARCIAL. 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.
