dear friend,
open source is the foundation of all modern software. every app, website, and system we use today is built on open source. it is the most important driver of global GDP growth, powering innovation and businesses worldwide.
but building and maintaining open source is not easy. for open source to thrive, we need a sustainable model. that's where commercial open source software (coss) can come in: one of the best ways to create open, future-proof software while ensuring long-term success.
coss.com is the new holding company of cal.com, the pioneers of open source scheduling infrastructure and cal.com continues to be the 'google search' of our alphabet.
our mission is to build a home for amazing open source projects, giving them the support they need to grow and succeed.
for developers we are building the coss stack, a one line "npm install coss" package that includes everything you need to build your application, from email, sms, calendar APIs, scheduling, video conferencing, notifications and more.
@peer_rich Does it work for non-developers too?
Cal.com
@masump hmmm not really. coss.com is a developer tool kit at the end of the day. but veeeery vibe code compatible!

This doesn't look ready yet, there is no installation guide, not in github either, this page https://coss.com/origin seems to use the radix version still.

Don't see a way to adjust border radius, Origin UI used to have that.
SaaS Interface
@shafu variable for radius is --radius, just like in shadcn and Origin UI. That list is meant to show the new color tokens to be added, along with coss.com defaults.

@pacovitiello Hmm, but why not have setup mentioned that anywhere in the docs?
