Show HN: Culink – A social platform for curating and sharing link collections

Hi HN! I'm a solo developer from Korea, and I’ve been building Culink, a social platform for curating and sharing link collections — kind of like Pinterest for links (articles, tools, videos, resources, etc). Why I built this: I kept losing interesting links across scattered bookmarks. GitHub “awesome lists” are great, but they’re static — I wanted something more social, searchable, and collaborative. What you can do: - Create themed collections (AI tools, dev resources, startup guides, etc) - Collaborate and share collections with others - Follow curators you trust - Discover quality links through your network - Enjoy a simple, clean interface Tech stack: Next.js 15, NestJS, PostgreSQL, Azure Container Apps Current status: Just launched the English version on US servers, with example collections so you can explore right away.
