Calendly is the polished, widely adopted scheduling tool that just works out of the box. Cal.com is the open-source alternative you can self-host, customize, and extend. Calendly wins on polish and ubiquity; Cal.com wins on control, customization, and open source.
Pick Calendly if you want the most polished, recognizable scheduling tool that works out of the box with almost no setup.
Pick Cal.com if you want an open-source scheduler you can self-host, customize deeply, or white-label for your own product.
Calendly and Cal.com both turn the back-and-forth of booking a meeting into a single shareable link, but they come from different philosophies. Calendly is the established, polished product — clean, dependable, and used by enough people that recipients already recognize it. Cal.com is the open-source challenger: you can self-host it, customize the booking flow, and extend it through an API and app ecosystem, which appeals to developers and teams who want control over their scheduling infrastructure.
On price, both have free tiers; Calendly's paid plans start around $10 per seat per month and Cal.com's team plans start around $15 per user per month (with a free self-hosted route). The choice is mostly polished, out-of-the-box scheduling (Calendly) versus open-source flexibility and control (Cal.com).

Things neither product's marketing page leads with.
Calendly is more polished and instantly familiar to the people you send links to, but it is closed-source and less customizable.
Cal.com gives you open-source control, self-hosting, and white-labeling, but the hosted polish and brand recognition trail Calendly slightly.
For a quick, dependable link Calendly wins; for control over your scheduling stack Cal.com wins.
