Cal ID is a fully open-source scheduling tool for solos and teams, with unlimited meetings, comprehensive integrations, real human support – and amazing features shipping at lightspeed.
If you’re tired of “just another scheduling tool”, let me spark your curiosity again – Cal ID is beyond scheduling.
We’re democratizing productivity so solos and growing teams can stop wrestling with reminders, timezone math, and admin, and get back to the work that actually matters.
Here’s why people love Cal ID:
Truly unlimited. The free plan has no feature limits and no commission on paid calls.
Sleek booking links like cal.id/rishabh (looks premium, right?)
Personalized onboarding & support where real humans help you set up fast.
Comprehensive integrations make scheduling a part of your workflow.
We ship fast. Our best features came from user requests that we built in record time.
Fully open source. You can explore, self-host, or contribute – no black boxes here.
Always affordable (pinky promise 🤙)
The enterprise plan is currently free for early adopters. Even when the paid plan arrives, it will stay genuinely affordable for the value you get.
We’ve now got 4,000+ users who’ve ditched paid tools and turned booking links into revenue streams – consultants, solo founders, agencies, coaches, recruiters.
Looks like an amazing tool that can replace our expensive Calendly subscription.
I created an account and it looks like the free plan is truly unlimited, love that it's based on Cal.com because it's instantly familiar
I needed my freelance clients to book calls from my website, so I gave Cal.com a try a year back.
I was honestly impressed with how quick the setup was. I had my account created, my main calendar connected, and my availability set in just a few minutes. I didn't run into any complicated settings or technical hang-ups.
My booking page looks great, it's super clean, and it just works. It's been a total breeze to use so far.
Finally! I have been trying to find a simple scheduling platform that integrates with the different tools our company uses. Got the whole thing set up, and integrated with our video conferencing (Webex) and calendar (Zoho) in less than 5 minutes. Thank you!
Looks like a great tool - i've been looking for a Calendly alternative and Microsoft Bookings doesn't allow payments so this could be a great new tool for our team
Unlimited meetings without throttling emails or API usage? Clarify what “unlimited” really covers.
Your booking page is pretty cool, but most schedulers are “good enough” on UI. What’s the measurable impact then?
Congrats on the launch @sanskarix ! Cal ID looks neat, always happy to see open source projects :))
Congratulation on the launch! It looks like a good alternative to Calendly. Do you integration with n8n?
@rohit_gadia and Cal team - many congratulations. I've used the mobile version of Cal and totally love it - really slick onboarding and ease of use. All the best!!
Impressive!
Any plans for branding kits, fonts, color tokens, and saved themes across teams?
actually better than calendly, if you are struggling with one event allowed in free version of calendly , this could be one of the best alternatives in the market.
Time zones and DST are sneaky, do you auto-handle edge cases for recurring slots?
