Bookmark Ninja

Bookmark Ninja is an online bookmark manager that allows users to organize, access, and share their web bookmarks across various devices and browsers. It features a customizable dashboard with tabs and categories, advanced search, tag management, and tools for finding duplicates and dead links. Users can import existing bookmarks and add new ones via browser extensions or bookmarklets.

Bookmark Ninja is a strong match for URList. It offers comprehensive bookmark management, allowing users to organize links into 'Tabs' and 'Categories' (similar to lists and sections). It supports adding notes to bookmarks, which aligns with 'contextual-side-notes'. Public sharing of 'Tabs' is explicitly mentioned, fulfilling the 'public-sharing' feature. The platform emphasizes quick bookmarking via extensions/bookmarklets, matching 'instant-link-adding'. Its UI is described as 'clean and simple', aligning with 'minimalist-interface'. User accounts are required for management, covering 'sign-in-authentication'. The ability to share specific 'Tabs' with optional password protection indicates 'granular sharing permissions'. Lastly, it's accessible on any device with a 'dedicated, native mobile-app like UI', confirming 'mobile-responsive-design'. While it doesn't explicitly mention inline previews of various media types, its core functionality strongly aligns with URList's purpose.
