Calendly vs Cal.com
Cal.com costs less per user and has a free plan, but its main code is no longer open source; only the reduced Cal.diy fork is.
Pick Calendly if…
You want a long-established booking tool with many integrations and don't mind $16 per seat for Teams. You'd also pick it if you want one clear product with no fork to think about.
Pick Cal.com if…
You want a cheaper per-user price ($12 for Teams) or a free plan with unlimited event types. If you must have open-source code, use the separate Cal.diy fork and accept fewer features.

Both tools offer a free plan. Calendly's Free plan covers one event type and one calendar connection. Cal.com's Free plan, listed as free forever for 1 user, includes unlimited event types and calendars.
On paid plans, Calendly lists Standard at $10 and Teams at $16 per seat per month, and Enterprise from $15k per year. Cal.com lists Teams at $12 and Organizations at $28 per user per month on its yearly option, and Enterprise at custom pricing. Neither page names the currency beyond the $ sign, and Calendly's page does not say if its figures are monthly or annual billing.
Cal.com was an open-source project, but on April 14, 2026 (the blog's byline date) it said it moved its production code to a private repository. The old GitHub address now holds Cal.diy, an MIT-licensed community fork with enterprise code removed. Cal.diy is self-host only and drops Teams, Organizations, Insights, Workflows and SSO/SAML, and its README advises it mainly for personal, non-production use.
So the choice is mostly price and plan limits, not licence. Cal.com's hosted product is the closer match to Calendly's features; Cal.diy is for people who value open code over team features.
