coss.com

the beautiful open source design system by @calcom built on top of @base_ui and @shadcn CLI

[coss.com @coss_com]

Origin UI is joining @calcom

It’s now @coss_com, a more ambitious project, set to become the best infrastructure for the web

We’re already working on the new UI library that will power the platform and remain open to everyone building great UIs

Exciting times for open source!

Flight timetable built with @tan_stack table + @base_ui + @coss_com ui 👌

[Pasquale Vitiello @pacovitiello]

Refactored the Toast component to support anchored positioning and a tooltip-like style

[Peer Richelsen @peer_rich]

proud to be on there with @coss_com ui 😍🥰

[Ali Bey @alibey_10]

Here is an awesome shadcn alternative

Coss UI (previously Origin UI) by @coss_com. beautiful, slick, accessible React components, built on @base_ui, and maintained by top frontend engineers like @colmtuite

Still, if you want to stick with Radix UI, nothing really matches what @shadcn offers

[Tyler Palmer @Tyler_Palmer9]

Made @Scheemeio a PWA for MVP. The mobile experience is slick now with it.

My stack for development..

@nextjs - 100% Typescript Web application
@coolifyio - VPS management & Deployment
@shadcn - UI components
@tailwindcss - CSS styling
@Hostinger - VPS Hosting
@tan_stack - Using Tanstack Query
@realkeydb - Server Cache
@tiptap_editor - Using for docs/editor
@dndkit - Best DND package IMO
@resend - Transactional Email
@Cloudflare - R2 Object Storage
@Docker - Containerized Deployments
@coss_com - Formerly Origin UI (Cal Components)
@better_auth - Currently NextAuth package
@geteslint - Linter
@stripe - Payments and billing/subscription management
@lucide_icons - React Icons
@prisma - ORM

I am sure I am missing tons more things I have running in this, but I have put this so you can know you can just do things...

Not an engineer by trade, and so many opinions here on X about the stack chosen and Next js this, and shadcn that. All of these things are battle tested and are simple to get going, so I highly recommend.
