Looks so vibe coded 🫩

 Really? Don't you like vibe coded products that are also secure?

Congratulations on the launch!

 Thanks a lot for your kind words

Kudos & congrats with your launch!

 Thanks for your kind words

What's the pricing model at founding.dev?

 Happy to discuss that with you. Can you please schedule a call here -

This is helpful, thank you!

 You are welcome! Please let us know if you have any feedback 🙏🏻

Hi Talha, I just gave you a follow, nice job with the launch today. I am the founder of , a platform for building no-code landing pages to send messages to any audience.

Customers of ours embed their calendars into their One Pagers and share them out to prospects and customers for outreach and touchbases. It could be a great use of Kalendar and may be helpful to market both of our products.

I'd love to find some time to chat on a potential collaboration.

 Hey Jake. Would love to connect. You can use our Kalendar as a drag and drop tool into your system. Would be a huge offering from your company to your users.

Happy to chat more here -

interesting product!

 Thank you Madalina, please we are open to hearing your feedback on what you'd need us to do to make you have the best experience with thanks!

Can multiple people share one booking link with round-robin or collective availability?

 Thanks for asking about this. Right now there's no ability to add a team. How important is this feature for you?

 Hi Zypressen, we are hoping that when you see question you'd respond. We are committed to making Kalendar as valuable as you require so it can serve you better, and you get the best experience out of it. We are very grateful for your support.

Hi and   — thanks so much for the thoughtful reply!
I don’t have a team myself, but I think this would be super helpful for remote teams coordinating across time zones — makes scheduling way less chaotic.
Really appreciate you considering it!

   100% the good thing about this is that with the parent platform teams can vibecode any feature they want - would be made public soon.

Nice one guys! A few days ago I was thinking about how shallow Google Calendar looks. Hope this goes well. Might give it a try. Would love to see an MCP around this to automate the process easier.

 Do give it a try. Later you will be able to import it as a template within Founding Dev and make any kind of changes on top of it.

Thats SO awesome!

 I’m glad you liked it and thanks a lot for your support.
