The Kickback Machine is powered down.
I built The Kickback Machine in Summer 2012 because I felt Kickstarter users could benefit from a research tool.
Since then, this site has become janky, and I simply don't have the time to maintain it. The good news is that better Kickstarter research tools have come along. If you want to explore past Kickstarter projects, I highly recommend Walter Haas's Kickspy.
If you're a researcher looking for lots of scraped Kickstarter data, you can find a database of ~87,000 Kickstarter projects here.
