Open Source Software

OSS Powers Everything

From smart switches to high-end servers, open source software now plays a significant role in just about every device with a CPU. The availability of freely usable and adaptable open source code has accelerated the rate of development and innovation in everything from the Internet of Things through to cloud based Artificial Intelligence.

Abivia has made code and/or financial contributions to several projects including the Joomla CMS, Laravel, LibreOffice, the PHP Foundation, and several others. We also develop and maintain our own projects. Some of our featured work is listed below.
