Cal.com

Cal.com is the open-source Calendly alternative core scheduling features available free and self-hosted, or pay for hosted convenience. The functionality covers standard scheduling needs. The open-source nature allows customisation. The pricing is more transparent than competitors. The hosted version is affordable. Compare against: Calendly for more polish and integrations, Lemcal for speed-focused booking, or just calendar invites if your needs are basic. Choose Cal.com when you want to avoid escalating SaaS pricing, need customisation not available in closed tools, or have compliance requirements requiring self-hosting. The self-hosted option requires technical capability. The hosted version lacks some polish. Best for technical teams, cost-conscious companies, or anyone wanting scheduling basics without paying premium prices for features they won't use.

Having implemented Cal.com for a client project in the past, I’ve gained valuable insights into its capabilities. Recently, while working with other meeting schedulers, particularly HubSpot's Meeting Scheduler, I conducted some desk research to evaluate and compare Cal.com against other tools like Calendly. In this article, I’ll share my honest review of Cal.com, highlighting its strengths, limitations, and ideal fit for businesses.

Strengths of Cal.com

Flexibility and customisation

Cal.com’s standout feature is its open-source nature. This provides unparalleled flexibility for users, allowing complete customisation of the platform. For B2B marketers and sales teams, this is a major advantage as you can tailor the scheduling process to fit your workflow. Whether you need to add custom fields to booking forms, integrate unique business processes, or adjust the design to match your branding, Cal.com offers the freedom to make it your own. This degree of customisation sets it apart from closed systems like Calendly, which offer more limited personalisation.

Feature set and integrations

Cal.com comes with a comprehensive feature set that supports one-on-one and group scheduling, along with integrations to Google Calendar, Zoom, and Outlook. This is essential for B2B marketers who need a seamless and professional scheduling experience. The integration with payment systems like Stripe is particularly useful for businesses that charge for consultations or events. Additionally, Cal.com allows you to implement advanced workflows, which is a significant advantage when managing a high volume of meetings.

Cost-effective

Another key advantage of Cal.com is its pricing model. The platform offers a free plan that includes most of the core features, which makes it an attractive option for small businesses and startups. Even for more advanced features, the paid plans are reasonably priced compared to other scheduling tools like Calendly. For businesses that are looking for an affordable yet powerful scheduling solution, Cal.com delivers excellent value.

Limitations of Cal.com

Technical expertise required for self-hosting

One of the limitations of Cal.com is the technical expertise required for self-hosting. Since it’s an open-source platform, it offers a high level of customisation and flexibility, but this comes at the cost of needing some technical skills. Self-hosting involves setting up servers and managing the infrastructure, which may not be feasible for teams that don’t have a technical resource available. For smaller businesses without an IT department, this could be a barrier.

Mobile app limitations

While Cal.com’s web interface is user-friendly and comprehensive, its mobile applications are still under development. This is a drawback for those who require robust mobile access to manage meetings while on the go. For teams that rely on mobile scheduling and meeting management, this lack of a fully functional mobile app could limit the tool's effectiveness.

Customer support

Although Cal.com is a solid tool, some users have mentioned slow customer support response times. When implementing a scheduling tool at scale, prompt support is crucial to resolving issues quickly. For businesses that need immediate assistance or troubleshooting, this could be a frustration. While the platform does have an active community, there may be times when a more direct response from the support team would be beneficial.

Ideal fit for businesses

Cal.com is ideal for businesses that require a high degree of customisation and control over their scheduling processes. It’s particularly suitable for B2B marketers and founders who need a flexible solution that can scale with their business. If you have the technical resources to host and customise the platform, Cal.com offers a powerful and cost-effective option.

However, if your team lacks technical expertise or if you need a highly responsive customer support system, you may want to consider other alternatives like HubSpot Meetings or Calendly. These tools offer user-friendly interfaces with less technical overhead but may not provide the same level of flexibility and customisation as Cal.com.

In conclusion, Cal.com is a strong contender for businesses that need an open-source, customisable scheduling solution. Its feature set, cost-effectiveness, and flexibility make it a solid choice for B2B marketers, especially those with the technical resources to take full advantage of its capabilities. However, for teams that prioritise ease of use, mobile access, and responsive support, other meeting schedulers may be a better fit.

‍

Cal.com is best suited for B2B marketers and founders who value control, customisation, and cost-effectiveness in their scheduling tools. It’s particularly beneficial for businesses with the technical resources to self-host or customise the tool according to their specific needs. If you’re managing a large team or running a scaling business, the flexibility and feature set of Cal.com make it a good choice. However, if you’re a non-technical user or need robust mobile functionality, you might face challenges with the tool.
