Cal Vs Calendly

is there any reason to prefer one over the other? Have you used both or either?

My needs are simple. I want to be able to add two accounts and let someone put a meeting on my calendar from a link. I think both cover the use case -- which should I use?

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.

I really like the UX and ease of the product but have faced a challenge with cal video experience: Pro: - The scheduling page looks quite decent and the best part is in the free plan, branding is removed which makes it better than Calendly Con: - Whenever I start the meeting, it always shows an error for the video with an error. I have to always close all my browser tabs and then it connects to the FaceTime cam. Not sure if it with me or with other folks.
