Cal.com vs TidyCal

Cal.com is an open-source scheduling platform positioned as the Calendly alternative you can own. The hosted version is free for individuals with unlimited event types; teams pay per seat for round-robin, routing forms and workflows. The code is on GitHub, and companies can self-host or embed scheduling into their own products with Cal.com Platform APIs and atoms.

It supports many calendars and conferencing tools, includes its own Cal Video, and offers payments, workflows (reminders), and dynamic group links. Development is fast and public.

The product occasionally feels less polished than Calendly, and self-hosting requires maintenance, but for price, openness and embeddability it leads the category.

Cal.com offers an Enterprise plan with SSO and dedicated support, and exposes bookings, availability and routing through a public API and webhooks. That is why product teams often treat it as scheduling infrastructure rather than a standalone booking link, which is the clearest difference from Calendly. For individuals the practical advice is simple: start on the free plan and pay only when you need team features such as round-robin or routing forms.

TidyCal is a scheduling tool made by AppSumo, the software deals marketplace founded by Noah Kagan in Austin, Texas. Its main selling point is pricing: a free plan covers unlimited bookings, a low-cost Pro subscription unlocks all features, and lifetime licenses have also been sold through AppSumo as one-off deals.

Users create booking types for different kinds of meetings, share booking pages and let invitees pick times that sync with Google Calendar, Outlook or iCloud calendars to prevent double bookings. It supports video links for Zoom and Google Meet, buffer times, booking limits, reminders and confirmations, group bookings for workshops, packages for selling several sessions at once, and paid bookings through Stripe or PayPal. Custom questions, automatic time zone detection and simple branding cover most of what a solo professional needs.

TidyCal suits freelancers, coaches and consultants who want reliable booking and paid consultations without an expensive recurring bill. It has limited team features such as round-robin routing, fewer integrations and basic customization, so teams needing lead routing and CRM connections should look at Calendly, Chili Piper or SavvyCal. Cal.com is an open-source option with a generous free tier, and Zcal is another free alternative. For one person selling their time, the free plan and low Pro price are hard to beat.
