Considerations

Cal.com stands out as a developer-friendly, privacy-first alternative to mainstream scheduling tools. It offers full flexibility for companies that want a self-hosted solution.

Best for companies needing custom scheduling

Unlike closed-source tools like Calendly, Cal.com allows businesses to fully control their data, customise branding, and integrate deeply with internal systems.

Strong API and developer support

Cal.com is designed with API-first architecture, making it ideal for companies wanting to embed scheduling into existing workflows.

More technical setup required

While powerful, Cal.com requires some development expertise to fully customise and deploy, making it less suitable for non-technical teams.

Best for:

  • Businesses needing self-hosted or custom scheduling.
  • Developers integrating scheduling into internal systems.
  • Companies prioritising privacy and data control.
