User Opinions

"In no time at all, Altova DiffDog identified a minute discrepancy between our XML files that would have taken me hours to identify manually. Problem found equals problem solved - I'm a DiffDog fan for life!"

- Michael Mullins, Applications Developer, West Virginia Division of Natural Resources

"DiffDog saved my life! Recordare developed MusicXML as an Internet-friendly format for publishing and sharing digital sheet music. As MusicXML became more popular, we needed a truly XML-aware differencing program to evaluate the XML files created by our Dolet plug-ins. DiffDog gives us the high quality regression testing tool that we had long sought for our MusicXML projects."

- Michael Good, CEO, Recordare
