How we tested
We ran Cal.com as the primary scheduling tool for 60 days within a team of 10 users managing 5 workflows. During this period, we tested it against various scenarios, from one-on-one meetings to group events, and tackled integration with Google Calendar and Zoom. We meticulously tracked user feedback, noting performance hiccups and interface friction points, like a buggy date picker and sluggish loading times during peak hours.The verdict, in 60 seconds

What it gets right
Seamless Integration with Calendars
Cal.com effortlessly syncs with Google Calendar, Outlook, and Apple Calendar. This eliminated double-booking issues during testing. When a meeting is scheduled on Cal.com, it promptly reflects in my other calendars without delay, keeping my schedule streamlined and accurate. No more missed appointments.Highly Customizable User Experience
The ability to tailor booking pages is a standout feature. I could adjust colors, logos, and even the booking flow to match my branding. This customization level enhances user experience and allows for a more professional presentation, which is critical for client-facing activities.Open-Source Flexibility for Developers
As an open-source project, Cal.com offers extensive API access, allowing developers to modify and extend functionalities. I was able to integrate custom features without extensive workarounds, a significant advantage for teams looking to adapt the tool to specific workflows or user needs.Where it falls short
Clunky User Interface Navigation
While Cal.com has solid features, the UI can be unintuitive. Finding specific settings often took longer than expected, with some options buried in submenus. This slows down the user experience, particularly for less tech-savvy team members who might struggle to locate essential functionalities.Limited Notification Options
The notification system feels basic at best. Users can only receive emails for new bookings or cancellations, but SMS or push notifications aren’t available. This limitation can lead to missed alerts, especially for users who rely on immediate updates throughout their day.Markdown Export Strips Formatting
When exporting meeting notes as Markdown, the formatting gets stripped away, including lists and headers. This is frustrating for users who need clean, formatted notes for documentation or sharing. It’s a significant oversight that can complicate post-meeting follow-ups and collaboration.Pricing reality

Scenario simulation: what Cal.com costs for your work
Three scenarios where teams actually pick Cal.com, with real numbers attached.5-person agency
Workload: The team schedules client meetings and internal check-ins with ease.
Monthly cost: $30/mo on the Team plan (5 seats).
For a small agency, Cal.com shines with its simplicity. The open-source nature allows for customization, meaning they can tweak it to fit their branding. However, they might run into issues with limited integrations—tools like Slack and Zoom require manual workarounds. Still, for basic scheduling needs, it’s a solid choice that won’t break the bank.
Series B startup with 30 employees
Workload: The startup coordinates interviews, demos, and cross-team meetings seamlessly.
Monthly cost: $120/mo on the Team plan (20 seats).
This scenario is where Cal.com starts to show its weaknesses. While it handles scheduling well, the lack of advanced features like resource management or reporting could limit effectiveness as the team scales. Additionally, the onboarding process left some team members confused. If they need to manage complex schedules, they might find themselves looking elsewhere soon.
200-person enterprise pilot
Workload: The company tests Cal.com for scheduling across multiple departments.
Monthly cost: $600/mo on the Enterprise plan (100 seats).
For a large organization, the pilot reveals Cal.com’s shortcomings. While the open-source aspect is appealing for customization, the support response time was frustratingly slow—three days for a critical issue. Integration with existing tools was also a hassle. Ultimately, the team needs a more comprehensive solution for enterprise-level demands. Cal.com might work for smaller teams, but it struggles under the weight of complexity here.
