Open source is dead.
That’s not a statement we ever thought we’d make.
@calcom was built on open source. It shaped our product, our community, and our growth. But the world has changed faster than our principles could keep up.
AI has fundamentally altered the security landscape. What once required time, expertise, and intent can now be automated at scale. Code is no longer just read. It is scanned, mapped, and exploited. Near zero cost.
In that world, transparency becomes exposure. Especially at scale.
After a lot of deliberation, we’ve made the decision to close the core @calcom codebase.
This is not a rejection of what open source gave us. It’s a response to what risks AI is making possible.
We’re still supporting builders, releasing the core code under a new MIT-licensed open source project called cal. diy for hobbyists and tinkerers, but our priority now is simple:
Protecting our customers and community at all costs.
This may not be the most popular call.
But we believe many companies will come to the same conclusion.

The best thing about good marketing is that it doesn't feel like marketing.

Tomorrow night, we're hosting Cal.FM
A cafe listening room for friends of Cal to escape the tech week panels, pitches, and badges.
Drinks, bites, and a room that takes their mission seriously, and selves unseriously.
Come solo, come with friends, leave with new ones.
Limited capacity, RSVP at Cal.FM

Built a voice agent that can book clinical appointments end to end.
It talks to the user, checks doctor availability via @calcom, finds a suitable slot, and books it.
Used @DeepgramAI for STT/TTS and Gemini 3.1 Flash Lite.
