Become a sponsor to Philipp Wolfer

I am a software developer and free software / open source enthusiast. In the last 20 years I have been contributing to a wide range of FOSS projects. My current main focus is software related to MusicBrainz, where I am currently the main developer for MusicBrainz Picard, and GNOME related software. Among my personal projects are:

  • Picard Barcode Scanner: Android app that allows you to use your phone as a barcode scanner to load releases into Picard.
  • MusicBrainz Magic Tagger Button: Browser user script to automatically enable the green tagger button on
  • Peek: A small screen recorder with a focus of generating short animated GIFs

I am also active in various other open source projects and contribute small patches to software I use.
Currently I am the main developer on MusicBrainz Picard, but also maintain some other MusicBrainz related software.

Please follow me on


See that my work is appreciated and motivate me to continue what I do 🚀
