Simple tool for saving bookmarks for web pages in a browser independent format, which promotes simplicity over intergration.
Once upon a time Delicious used to do quite a good job of keeping track of your bookmarks in a satisfactory manner. Time changes, but the needs are still present.
Trying to keep things as simple as possible, focusing on core features such as save and search. While automatic syncing is usually considered an important feature of a bookmark keeper, I recommend Syncthing for that.
