diffoscope is a tool to get to the bottom of what makes files or directories different. It recursively unpacks archives of many kinds and transforms various binary formats into more human readable forms to compare them.
diffoscope is being developed under the umbrella of the reproducible-builds.org effort, a member project of the Software Freedom Conservancy. For contributing, licensing and instructions on how to run diffoscope on your own machine, please see diffoscope.org.
