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.
Would love to hear your feedback!

Who hunted Cal ID?
Cal ID was hunted by Rohan Chaubey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
