The strongest free Calendly replacement: unlimited event types and calendars on the free plan and cheaper team seats, but it is no longer open source since April 2026, and the self-hostable community edition drops the team features.
What it is
Cal.com is a scheduling platform: booking links, availability across connected calendars, email and SMS reminders, payments through Stripe or PayPal, routing forms and team scheduling (round robin, collective and managed event types), plus an API and embeds for building scheduling into a product. The free Individuals plan has no usage limits: 1 user, unlimited links and calendars, 100+ app integrations, two-way Salesforce and HubSpot sync and a one-click import of Calendly event types. Teams is $12 per user a month billed yearly (round robin, routing forms, recurring events, booking analytics, removes Cal.com branding); Organizations is $28 per user a month billed yearly (sub-teams, company subdomain, SAML SSO and SCIM, SOC 2 and HIPAA compliance); Enterprise is on quote. Paid plans have a 14-day free trial and cost more billed monthly. In April 2026 Cal.com moved its commercial code to a private repository, citing AI-assisted vulnerability hunting; the public code continues as Cal.diy, an MIT-licensed community edition for self-hosting that removes Teams, Organizations, Insights, Workflows and SSO and is recommended for personal, non-production use. Checked on cal.com November 13, 2026.
Best for
- Individuals who want a free scheduling link without Calendly's one-event-type limit
- Teams that need round robin and routing forms at a lower per-seat price
- Developers embedding scheduling in their own product through the API
What we like
- Free plan with unlimited event types, calendars and integrations
- Teams at $12 per user a month billed yearly, below Calendly Teams at $16
- One-click import of Calendly event types
- API, embeds and webhooks built for developers
What to watch
- No longer open source: the self-hostable Cal.diy edition lacks team features and is recommended for non-production use only
- Removing Cal.com branding and round robin need the paid Teams plan
- SSO and SCIM only on Organizations at $28 per user a month
- Smaller integration catalog and fewer enterprise sales add-ons than Calendly
