I used to use pinboard[1] but since I started dicking around with self hosting I use Wallabag[2] for “read it later” articles and linkding [0] for saving links that I want to refer to later. Linkding is pretty much a self hosted pinboard
Linkding is my current favorite self-hosted solution in this genre. Used Pocket for a long time but like the tagging and minimal looks of linkding better.
