There are many different bookmarking programs available at this time. I have listed 2 self hosted types here, Hoarder and Linkwarden. I do not know which is “better”.
I am not sure I like the concept in Hoarder which used 3rd party AI to assist with bookmarking tagging. Perhaps it works well.
Hoarder is an open source “Bookmark Everything” app that uses AI for automatically tagging the content you throw at it. The app is built with self-hosting as a first class citizen.
Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. The objective is to organize useful webpages and articles you find across the web in one place, and since useful webpages can go away (see the inevitability of Link Rot), Linkwarden also saves a copy of each webpage as a Screenshot and PDF, ensuring accessibility even if the original content is no longer available. Additionally, Linkwarden is designed with collaboration in mind, sharing links with the public and/or allowing multiple users to work together seamlessly.
