About Cal.com

Cal.com started as an open-source answer to Calendly and has grown into a full scheduling platform. Individuals get booking pages with unlimited event types and calendar connections for free, including payments through Stripe or PayPal and two-way sync with Salesforce and HubSpot. Paid team plans add round-robin and collective events, routing forms, managed event types and the option to remove Cal.com branding, while the Organizations tier adds sub-teams, SAML SSO and compliance features such as HIPAA. Developers can embed booking components, use the public API, or run the whole stack themselves from the source code with Docker. The hosted service is priced per user per month with a 14-day trial for paid plans. It works in the browser, with mobile apps and a browser extension. The trade-off for the flexibility is a busier settings area than simpler tools, and self-hosting means you maintain the database, cron jobs and upgrades yourself.

Best for: Individuals who want a free Calendly-class tool, and teams that want to self-host or embed scheduling.
