Open Source

AppNexus uses quite a bit of free and/or open source software, and this software provides tremendous value to the company. AppNexus engineers also create a tremendous volume of interesting software themselves! As a company, we have a desire to contribute back to the open-source software community that has helped AppNexus become the technology company that it is today. We fulfill this desire by making some of our more general purpose, non-proprietary software available to the general public using reasonable open-source licenses.

  • pyrobuf: A self-contained, easy-to-install alternative to Google's Python Protobuf library.
