Review Cal.com?

Reviewers mostly praise Cal.com for a clean, minimal interface, easy setup, and smooth scheduling that often feels better than Calendly. Repeated strengths include flexible customization, self-hosting, embeds, open API access, calendar integrations, time zone handling, and built-in video calls. A few makers, including the teams behind Don’t Panic by Lemon.io and LaunchSafe, also say it works well for integrations and embedded booking flows. Criticism is narrower but clear: some users report weak support, Microsoft calendar issues, outages, and frustration over open-source features being moved behind paid plans.

Used Cal for a bit now, and I prefer the easy to schedule as well as integration with M365 and other apps. The landing page to schedule a meeting is no jazz, simple and does the job. The backend setting allows users to customise with third party app developers and integrate the scheduling, payment with Stripe and workspace with either Google or Microsoft, all comes together. Very few or none out there on the product market are at par with Cal.com. Can't wait for Cal.ai to be in hands for general availability.

A Game Changer for Scheduling I've been using various scheduling applications over the years, but CAL has completely revolutionized my experience. The user interface is clean, intuitive, and visually appealing. It's incredibly easy to manage multiple calendars, set reminders, and coordinate meetings across different time zones. The app's seamless integration with other platforms like Google Calendar and Outlook is just the cherry on top. This is a must-have tool for anyone looking to stay organized and efficient. 5/5 stars, hands down because of its inbuilt video conferencing tool called as Cal Video.

Great feature. However, as cal.com can still not connect to MS Exchange 2019 calendars, this renders the whole service unusable for everyone using a current version of MS Exchange... 🤔 I'd prefer they allowed people using their service in the first place, before pimping it with nice-to-have features.

I recently started using Cal.com, and I'm thoroughly impressed. The app is incredibly intuitive, making scheduling a breeze. The design is sleek and aesthetically pleasing, which adds to the overall experience. What truly sets Cal.com apart is the generous free plan, offering features that many other services would charge for. Plus, the customer support is outstanding—quick, responsive, and genuinely helpful. I highly recommend Cal.com to anyone looking for a reliable and user-friendly scheduling solution!

Cal.com is a fantastic open-source alternative to Calendly. Its flexibility to self-host or use a hosted solution, along with advanced customization and an open API, made integration into my business seamless.

It's ridiculous for Cal.com to call itself "open source" after pulling a classic bait-and-switch. They attracted a community by offering key features like team member functions, only to rip them out of the open-source version and lock them behind a proprietary paywall. This move is a betrayal of the open-source spirit and a genuine shame for a project that once held so much promise.

Very happy with cal.com It has some great quality of life features that I like. The open-source ethos is great for a techy so I can create an issue and they can decide whether to implement or not. The workflow for both sides is a lot more pleasant than calendly, fantastical, and a few others I've tried. Excited to try out cal.ai

I like the interface, it's simple and minimalistic. Calendar integration and also pixel integration are seamless. Additionally, customised reminders are also something useful. Though I haven't experienced this before right now, the site is down. I hope it gets resolved soon.

The product has a direction and a goal aligned with what I need out of a calendar, getting my meetings scheduled easily. Cal.com accomplishes this and when I've had an issue, which turned out to be user error, they were right there to help me.

Had an issue logging in and Peer (CEO) tended to the matter within the hour. I haven't had such responsive customer service so this was quite the experience. It's refreshing to find a customer-centric open source project do so well.
