Build me a full stack app where developers can save and organize useful links like docs, tutorials, GitHub repos, and tools.

I want users to be able to sign up and log in, then add a resource by pasting a URL and having the app automatically pull the title, description, preview image, and favicon. They should be able to edit, delete, favorite, copy, and open items, plus see a clean details page for each one.

Please include fast search, filters for category, type, and favorites, sorting, pagination, and a clear filters option. Add a dashboard with stats, a categories page, a favorites page, and settings where users can edit their profile, switch light and dark mode, and export their bookmarks as JSON.

Make it feel polished with loading skeletons, empty states, toasts, delete confirmations, and a responsive layout that works well on desktop and mobile. If it fits, also include a simple free, pro, and team plan flow in test mode with resource limits and custom categories for paid users. Use the current docs online if you need to check anything.
