Definitely not as featureful as something like this, but when Delicious started to go down the pan I switched to a simple Ruby script and a Dropbox-synced data file between all my machines. Several years in, it's still working a treat! "Dropbox + simple script" seems to be a great mechanism for many apps if you don't need easy public access.
