Cal.com
Open-source meeting scheduling software with unlimited free bookings and developer APIs.
If you're paying Calendly for one person, moving to Cal.com is one of the easiest cost wins in SaaS — the free tier is genuinely unlimited. The catch is setup. Non-technical teams will feel the configuration overhead, and Platform is closed to new signups as of December 15, 2025, so anyone needing that path should look at Organizations or self-hosting instead.

About Cal.com
Cal.com is an open-source scheduling platform for booking meetings without the back-and-forth. It connects to your calendar, cross-references availability, and generates a booking link you can share anywhere. The free Individuals plan stays unlimited for one user, which is why so many people migrate off Calendly after hitting paywalls. Availability controls cover the practical stuff: buffers before and after events, minimum notice, and daily, weekly, or monthly booking limits so your week doesn't fill up on 15-minute calls. The booker side is handled too. Visitors can overlay their own calendar, get confirmations by email or SMS, add the event to their calendar, and reschedule themselves. Automated email and SMS reminders plus follow-ups cut no-shows. Payments run through Stripe and PayPal, and Cal Video is the built-in conferencing option when you don't want to bolt on Zoom. For teams, Teams adds round-robin, managed and collective event types, routing forms, and booking analytics. Organizations layers on SSO with SAML and SCIM, a company subdomain, role-based permissions, and compliance coverage for SOC 2, HIPAA, and ISO 27001. Developers get React atoms for embedding the booking flow, an OAuth client, and webhooks, with 100+ app integrations and 65+ languages. Against Calendly, Cal.com trades polish for control and cost. Self-hosting is available for privacy-sensitive teams, and there's no per-seat charge for individuals. If you want scheduling that plugs into your own product rather than living in a separate tab, that's the trade that matters.
Behind the Verdict
Where Cal.com earns its keep is the free tier. Unlimited event types and calendars for one user, no usage cap, no credit card. Most solo operators never need to pay, and that alone justifies the switch from Calendly. Teams is where it gets interesting for small companies. Round-robin, collective events, and routing forms distribute inbound leads across shared availability without someone manually assigning calls. At $12 per user/month billed yearly, that's the working plan for startups with a combined calendar problem. Organizations, at $28 per user/month yearly, is the compliance answer — SAML SSO, SCIM, company subdomain, and SOC 2, HIPAA, and ISO 01 coverage. Worth noting: Platform was retired for new signups on December 15, 2025. Existing enterprise customers keep support, but new buyers should treat Organizations or self-hosting as the path. Developers get the most out of Cal.com. React atoms drop the booking flow into your app, the OAuth client handles auth, and webhooks fire on booking events. If scheduling is a feature inside your product, this is the part competitors are weakest on. The honest downside is setup. Availability, buffers, and event types are configured, not defaulted. Non-technical users who just want a link will find Calendly faster to live with, and the UI, while improved, still asks more of you. Integration depth is the other watch-out. Salesforce availability appears in iCloud sync, HubSpot is there too, but sales teams leaning on deep CRM routing may find Cal.com shallower than territory tools. Pick it when flexibility and cost matter more than out-of-the-box polish.
