linkding
linkding is a bookmark manager built around tags, so every saved link can be filed under as many topics as you like and revisited later through a searchable archive. It supports bulk editing, a bookmarklet for quick saving, a scraper that pulls titles and descriptions from pages, sharing links for other people, and browser extensions.
People use it as a durable, self-managed alternative to a cloud bookmark service, and teams share read-later lists through it.
Running it on your own server keeps your reading history out of somebody else's account, with no subscription and a database small enough to back up in seconds.
