Reviewers say Cal ID makes scheduling easier and cuts the usual back-and-forth, with praise for quick setup, clean booking links, custom schedules, multi-calendar sync, reminders over email and WhatsApp, and payment support through Razorpay. Users also value how many features are available without early limits, especially for teams. The main criticism is polish: some find parts of the UI cluttered, advanced setup can feel heavy for non-technical users, and one reviewer reported slow booking or cancellation and problems with Jitsi. A founder of
HTTPDump adds that team routing and support have worked well at scale.

Would love native integrations with Zoom/Meet/Teams, plus a fallback if tokens expire.
@manab_boruah Good news , we already support integrations with Zoom, Google Meet, and Microsoft Teams with Jitsi as the default video conferencing provider, so your calls stay uninterrupted.

@istiakahmad Thank you! We’ve built Cal ID to be open, reliable, and designed with great care in every detail.
@istiakahmad Thanks, Istiak!
I've read your blogs and guides before. It's great that you liked the open-source system, it was built to be utterly transparent and open for devs to give it their own touch ;-)

I like the team consultation feature - that's incredibly helpful - and so clean overall

The team consultation part was one of our most requested features, so great to hear it’s making things smoother. Any ideas for what you’d love next? 🤔
