BibDesk

BibDesk is a free and open-source bibliography manager for macOS, designed to help users organize and manage their bibliographic data, particularly for LaTeX users. It allows for the management of references, including associated files and web links, and offers features for importing, exporting, and searching bibliographic information from various sources and online databases.

BibDesk is a bibliography manager for Mac OS X, primarily focused on managing BibTeX files. While it allows users to manage bibliographic information and associated files or web links, and organize them, it is not a general-purpose URL curation tool like URList. It supports linking to web pages and local files (like PDFs) and has features for importing and exporting references, which can include URLs. It also has a 'Web group' for browsing web databases and scraping references. However, it lacks the explicit 'contextual side notes' and 'public sharing' features as described for URList, which are core to URList's value proposition of sharing curated lists with non-users. Its primary function is academic bibliography management, not broad web content curation and sharing.
