Cal.com is a scheduling platform with unlimited event types, round-robin booking, and 100+ integrations. See 2026 pricing, features, and pros/cons.
Cal.com is a scheduling platform founded in 2021 by Peer Richelsen and Bailey Pumfleet, originally released as Calendso before the team acquired the Cal.com domain and rebranded. The San Francisco-based company built its reputation on a commercial open-source model, pairing a free, self-hostable core with paid cloud and enterprise plans.
In April 2026, Cal.com shifted its main hosted product to a proprietary license, citing the risk of AI tools scanning public repositories for vulnerabilities, while open-sourcing a security-focused component called Cal.diy under an MIT license. The move drew both attention and criticism from the open-source community it had built.
Cal.com supports unlimited event types and booking pages, team-based round-robin and collective scheduling, workflow automation, and routing forms for qualifying leads before a meeting is booked.
It connects to more than 100 apps, including Google Calendar, Zoom, Stripe, PayPal, Salesforce, and HubSpot, and offers a public API plus embeddable booking widgets for developers who want to build scheduling directly into their own products. Native iOS and Android apps handle bookings and notifications on the go.
Cal.com's Free plan covers one user with unlimited event types and 100+ integrations. Paid plans scale per user: Teams starts at $12/month per user (billed annually) with a 14-day trial, and Organizations starts at $28/month per user (billed annually) adding SSO, SCIM, and compliance features. Enterprise pricing is custom.
