I use Cal.com to simplify my scheduling, allowing people to book meetings directly on my calendar without back-and-forth messages and it automatically handles time zones, availability, and buffers between meetings. It's really useful for setting up different event types like client calls, internal team meetings, interviews, or paid consultations. I appreciate its open-source nature, which means it can be self-hosted and deeply customized to match specific branding, workflows, and security needs. The integration with multiple calendars and tools is great; it keeps my availability in sync and reduces double bookings or missed meetings. Advanced features like booking limits and automated workflows make scheduling feel controlled rather than chaotic. Its API-first design and modular architecture are fantastic for scalability and building tailored booking experiences. I love that it connects with calendars like Google Calendar and Microsoft Outlook, ensuring all bookings appear alongside other events and stay in sync. It also integrates smoothly with video tools such as Zoom, Google Meet, and Microsoft Teams, automatically attaching meeting links to events. The cloud version’s onboarding flow is straightforward, guiding me through essential setup steps so I can start accepting bookings quickly. Review collected by and hosted on G2.com.

Running the self-hosted version reliably can require technical expertise, ongoing maintenance, and sometimes commercial licensing for certain enterprise or payment features. Some users expect a fully 'free and simple' open-source experience and are surprised by the complexity and constraints of the real-world deployment. Initial configuration of integrations, event rules, and custom fields can take more time than with minimalist tools, and troubleshooting misconfigured bookings or integrations sometimes needs digging through settings. There are also occasional reports of UI friction and smaller bugs, which, while typically resolved, can interrupt scheduling flows until fixed. The learning curve for advanced event rules, workflows, or team settings can be steeper. Review collected by and hosted on G2.com.

I love using Cal.com to manage and schedule my client meetings and appointments. The ability to automate bookings and share my availability easily helps me avoid the back-and-forth when setting up meeting times. I really appreciate the custom booking pages; they look professional and can be tailored to match my personal brand. This makes my booking page feel premium compared to generic scheduling tools. The integration with my calendar and other tools is seamless, ensuring my schedule is always up-to-date and preventing double-bookings. I also find the automated reminders crucial as they greatly reduce no-shows by notifying clients in advance without requiring any manual intervention from me. I am impressed by Cal.com's open-source nature, which provides transparency and flexibility, allowing the platform to consistently improve. Overall, it's a reliable and powerful tool for keeping my appointments organized and my workflow smooth. Review collected by and hosted on G2.com.

Occasional booking glitches; sometimes booking links load slowly or fail to open for certain clients, which can create friction. Calendar sync delays; I occasionally face delays or mismatched time slots, leading to confusion or potential double-bookings. Limited mobile experience; the mobile interface feels less smooth, and navigating settings or editing availability could be more user-friendly. Workflow complexity; some advanced features require extra setup or technical knowledge. More templates & ready-made layouts are needed; it would be helpful to have more built-in templates for booking pages, workflows, reminders, and branding. Review collected by and hosted on G2.com.

I appreciate Cal.com being open-source, which lets me fully customize and self-host without being locked into a vendor. It’s great that I can seamlessly embed branded booking pages into my site or socials, and use APIs to create custom workflows. The smart scheduling rules are really helpful, with features like automatic buffers and daily limits that help prevent burnout and scheduling conflicts. I find the AI via Cal.ai that parses emails to book or reschedule autonomously to be very convenient. The deep calendar syncs with Google, Outlook, and Apple calendars are reliable and prevent double bookings, which is a big plus for me. Review collected by and hosted on G2.com.

Cal.com's advanced features overwhelm new users, especially non-technical ones, requiring time to master organizational tools and customizations like event rules. Performance on a large scale is an issue as round-robin events with many team members load slowly, and complex queries can lag. Self-hosting demands technical skills for IP changes or maintenance, risking downtime if mishandled. Granular admin reports lack templates for quick insights, and the interface feels unintuitive for availability tweaks or viewing booked slots in public calendars. The free tier misses advanced personalization like custom booking pages. Review collected by and hosted on G2.com.

I like Cal.com because it solves the headache of scheduling by removing the back-and-forth of finding a time that works, allowing people to book directly based on your availability, and handling reminders, automatic time-zone detection, and integrations with the calendars or tools you already use. I appreciate how flexible and customizable it is compared to other scheduling tools. You can design booking pages that match your brand, create different types of events with unique rules, and integrate it deeply with the tools you already use. It provides full control over availability, workflows, and automations, making it work well for solo creators, businesses, or teams. The open-source nature is a big plus too, as you're not locked into a closed system and can adapt it as your needs grow. Plus, it's powerful without being complicated, which makes scheduling feel effortless. I also enjoy how Cal.com works best when paired with other tools, especially with integrations into calendar apps like Google Calendar or Outlook and video meeting platforms such as Zoom, Google Meet, or Teams. It even integrates nicely with CRMs or automation tools like Zapier, making it a full workflow system that saves time and keeps everything organized. Review collected by and hosted on G2.com.

A few areas could definitely be smoother in Cal.com, even though it’s already strong overall. The setup process can feel a bit overwhelming at first because there are so many options, so a more guided onboarding or clearer presets would help. Some of the advanced customization features also require technical knowledge, which might be a hurdle for non-technical users. The UI is powerful but occasionally feels dense, especially when managing multiple event types or workflows. And while the integrations are good, certain third-party connections could be more seamless or offer deeper controls. Review collected by and hosted on G2.com.

I like how Cal.com makes scheduling calls, meetings, and internal scheduling much easier for us. The flexible platform lets us set roles, availability, booking rules, and workflows, helping to avoid double bookings and confusion. The shared team calendar is great for seeing who is free or busy. The automation features, like reminders and confirmations, help reduce no-shows and keep communication clear. Integrations with tools like Zoom and Google Workspace save us time since everything works together. I love that it helps us stay organized and feel more professional in our scheduling. I also like how flexible it is, allowing us to create separate booking rules and workflows based on meeting types. The ability to set team routing rules to automatically send a call to the right team member is fantastic. These features make scheduling feel organized, smooth, and adaptable as we grow. Review collected by and hosted on G2.com.

Even though Cal.com has been helpful, there are a few things that could be improved. One area is the learning curve. Some features are easy, but the advanced settings and workflows took us time to understand. A more guided setup or clearer examples would make onboarding smoother. Another thing is that sometimes certain integrations need extra steps before they work the way we want. Everything eventually works, but the process could feel more seamless. We also noticed that customization is powerful, but it sometimes means extra work when creating new meeting types. Having more ready-made templates for common use cases would save time. One more thing I would add is around the user interface. Everything works, but some menu paths feel a little hidden or require extra clicks. A more streamlined layout or clearer labels would make it easier for new users to find what they need without trial and error. It would also help if there was a simpler way to duplicate or edit existing workflows in bulk. When our team grows or our process changes, we sometimes have to update things one by one. A bulk-edit feature would save time. Finally, having more built-in tutorials or short walkthrough videos inside the dashboard would make the learning process smoother. Overall, these are small improvement ideas, not major complaints. The product already does a great job, and with a few polish updates, it could feel even more effortless.

I like how I can set my own availability, add different types of meetings, and integrate it with my calendar on Cal.com. Once everything is set up, it all works automatically, which means people can book a slot, and I receive a clean confirmation without any manual work. It feels very professional and saves a lot of time. Review collected by and hosted on G2.com.

One thing Cal.com doesn’t work as well for me is the initial setup — it can feel a bit complicated. There are many settings, integrations, and options, so it takes time to understand everything. Once it’s set up, it works great, but the learning curve could definitely be simpler. The main thing Cal.com could improve is its setup process. There are so many features and settings that the initial onboarding feels confusing. A simpler step-by-step setup wizard, preset templates for common meeting types, and clearer explanations of integrations would make the experience much smoother. They could also improve the mobile dashboard and add a more intuitive preview mode so users can quickly see how their booking page will look. Review collected by and hosted on G2.com.

Our organization adopted Cal.com's Teams/Organizations plan and it has quickly become one of our most valuable operational tools. I really like Cal.com's centralized team scheduling dashboard, which lets us manage availability across departments without switching between individual calendars. The ability to define roles, assign booking rules, and create shared event templates has significantly reduced the workload on our operations team. I appreciate the granular permission controls that still give each team autonomy over their own calendars. Cal.com's native integrations with tools like Slack, Zoom, and our internal CRM automatically sync and update meetings, nearly eliminating double-bookings and scheduling conflicts. The analytics tools in the Organizations plan are surprisingly useful for capacity planning, giving us clear insights into booking volume and team productivity. I am impressed with Cal.com's extremely customizable scheduling, open-source and self-hosting options, and developer-friendly APIs, webhooks, and plugins. The team scheduling features such as round-robin, collective bookings, and pooled availability are very useful, and I find the transparent pricing much simpler and more predictable compared to other SaaS scheduling platforms.

1. Setup and configuration can feel complex. Because Cal.com is highly customizable and open-source, its setup—especially self-hosting—can be more technical than 'plug-and-play' tools like Calendly, with multi-service dependency setup (Postgres, Redis, etc.) and needing engineering help for deeper customization. 2. Documentation gaps. Some users feel that the docs don’t always cover edge cases or advanced configs, plugin development examples could be clearer, and self-hosting guidance can lag behind feature updates. 3. Occasional platform instability with new releases. Highly active open-source projects often move fast, leading to frequent changes that sometimes lead to regressions and new features debuting with minor issues. 4. UI/UX feels less polished compared to competitors. The interface feels more 'developer-centric,' with fewer small niceties and animations than competitors, and the admin dashboard could be more streamlined. 5. Marketplace quality varies. Since extensions/plugins can be community-built, some plugins feel incomplete, support levels differ, and quality control varies across contributions. 6. Learning curve for advanced automations. Webhooks, API flows, routing logic, and embed configs require technical skill, and some advanced flows lack step-by-step guidance. 7. Enterprise feature gaps. More refined user management features would help, as well as the need for deeper analytics or forecasting tools and SSO / SCIM setups can require extra tuning.

I love how Cal.com supports team-based scheduling with the shared availability feature, which combines all team members’ schedules into one unified calendar. This eliminates back-and-forth coordination and makes booking meetings almost instant. The routing options, like round-robin and group scheduling, are outstanding because they allow meetings to be assigned automatically and fairly, saving time and keeping workloads balanced. I really appreciate the admin dashboard in the Teams/Organization plan, which lets us assign roles, set permissions, and control access or modification of settings, bringing structure to our scheduling process. Customization is another highlight, as we can brand our booking pages, adjust workflows, and use automations to match our internal processes, giving a professional feel aligned with our brand. The analytics provide real value, offering insights into booking patterns, peak times, and team activity, helping us understand and improve our scheduling efficiency.

Cal.com works very well for our team overall, but there are a few areas where improvements would make the experience even better. One area is onboarding. Because the Teams/Organization plan includes advanced features like routing rules, workflows, and permission settings, new team members sometimes need extra time to understand everything. More guided in-app tutorials or walkthroughs would make the learning curve smoother. Another area that could improve is integration setup. The integrations work reliably, but some of them require a bit of manual configuration. Having more ready-made templates or simpler 'one-click' setup options would help teams get started faster. Lastly, while the analytics dashboard is useful, adding deeper insights—such as trends over longer time periods or more detailed breakdowns per team member—would make it even more powerful for decision-making. These are not major issues, but improving them would make Cal.com even more user-friendly and efficient for growing teams like ours. Review collected by and hosted on G2.com.

I use Cal.com to streamline scheduling without the usual back-and-forth. It’s great for booking client meetings, internal team calls, and even personal appointments. The customization options make it easy to match my workflow and branding. I love how Cal.com prevents double-bookings by syncing all my calendars in one place. I also appreciate its customizable and flexible nature compared to other scheduling tools, as I can tailor booking pages, workflows, and integrations exactly to my needs. The open-source nature gives it a level of transparency and control that’s rare, making scheduling genuinely enjoyable. It connects well with my calendar apps, video meeting platforms, and task management tools, helping automate reminders, meeting links, and follow-ups, making scheduling feel more connected and efficient. We were looking for something more flexible and customizable, and Cal.com fit those needs better, offering more control over booking pages and workflows compared to our previous tool, Calendly.

One thing that could be improved is the learning curve—some of the advanced customization options take time to understand. A bit more built-in guidance or templates would help. Occasionally, integrations need extra setup or troubleshooting. Ensuring permissions, API keys, or webhooks are set up correctly can take a bit more time than expected. It’s nothing problematic, just an area where clearer setup guidance could make the process easier. Review collected by and hosted on G2.com.

I love Cal.com's strong automation features as they help us manage workflows, generate reminders, send follow-ups, and create intricate routing logic, which significantly decreases administrative time for our teams. I appreciate how Cal.com streamlines our customer service scheduling processes, allowing our sales, support, and onboarding teams to arrange client follow-up meetings, technical consults, and demonstrations without the need for back-and-forth communications. The automated routing and centralized scheduling dashboards optimize our entire scheduling process. The integration with tools like Zoom and Google Workspace, which automatically synchronizes calendars and ensures meeting details are uniform across platforms, is fantastic. I like the customization options it offers, providing greater flexibility for team-based workflows and the capacity to handle several teams, routing rules, and automated workflows in one location. The first setup was very simple, thanks to the clear UI, useful suggestions, and logical actions that aided in configuring team members, event types, and connectors.

The team dashboard could be more user-friendly, despite Cal.com's strength. Some options in the Organizations plan are difficult to find. New team members might configure more quickly with a more structured grouping, like collapsible categories or a guided setup. A more simplified layout or faster shortcuts for frequently used settings would enhance the user experience. Review collected by and hosted on G2.com.
