About

I’m Marc Prud’hommeaux — a software developer based in New England.

I studied at Cornell University and have spent most of my career building developer tools and consumer apps across the JVM, Apple, and Android ecosystems. I currently serve on the board of the F-Droid project and I’m the creator of the App Fair Project, a noncommercial source for free and open-source mobile applications.

Notable Projects

• JLine (2002 – present) — author. A Java library for handling console input, used by many JVM REPLs and command-line tools.
• Apache OpenJPA (c. 2001 – 2007) — one of the original creators. Formerly known as Kodo, an object-relational persistence engine that was contributed to the Apache Software Foundation.
• Stanza (2008 – 2012) — creator. An early iOS and desktop e-book reader.
• Skip (2023 – present) — co-creator. A toolchain for building native iOS and Android apps from a single Swift codebase.
• App Fair (2022 – present) — creator. A community-run catalog and build infrastructure for free and open-source mobile apps.
