Hi, I'm Ivy.
After 6 years of support, Spotify finally retired their old API and Ivy can't quite work with the new one yet. This requires a rewrite of many parts of the tool. This will take some time. An ETA can't be given at this moment. I know a lot of people are enjoying Ivy and would like to see it back. It started as a hobby project back in 2010 and has since then grown to become a website where more than 200 people upload their playlists every day.
