Cal.com vs Calendly: Open-Source, Embeddable Scheduling vs the Market Leader
Calendly is the best-known scheduling tool, listed at $10 per seat per month (Standard) or $16 (Teams), billed annually. Cal.com is a scheduling platform whose open-source edition, Cal.diy, is MIT-licensed and can be self-hosted; its cloud lists Teams at $12 per user per month billed annually. On the cloud, the two cost about the same. Cal.com’s real advantage is that it can be self-hosted, white-labeled, and embedded into your own product or booking flow.

The honest answer
Choose Cal.com if…
- Scheduling is part of your product, portal, or booking funnel
- You need full white-labeling under your own brand and domain
- Booking data must stay on your own infrastructure — for example, in healthcare
- You need custom routing, intake questions, or integrations
Choose Calendly if…
- You just need reliable booking links for a sales or services team
- You want the fastest setup with nothing to host
- Your invitees already recognize and trust Calendly links
- You want a mature routing and enterprise admin feature set without customization
A worked example
For 20 seats billed annually, Calendly Teams ($16) is $3,840 a year and Cal.com Teams ($12) is $2,880 a year — a modest difference. Self-hosted Cal.diy has no per-seat fee, but you take on hosting and calendar-integration setup. Choose Cal.com for control and embedding, not mainly for price.
