In 2018, Deloitte, Datawheel and University of Toulouse Chair of Artificial and Natural Intelligence Toulouse Institute (ANITI) and co-founder of Datawheel, César Hidalgo, came together to embark on an ambitious journey—to understand and visualize the trajectory of open source technology, and to create a tool to inform important technology decisions. Emerging technologies—from cybersecurity and blockchain to machine learning and physical robotics—are being developed in an open source environment at a staggering rate. There are 30+ million developers working on more than 96 million software projects worldwide on GitHub (as of September 30, 2018).

Staying on top of this activity and navigating open source technology adoption can be a significant challenge. Too often, innovation efforts and investment decisions are made on limited data. Our team, comprised of open source and domain specialists, data scientists, data visualization pioneers and technology leaders across a range of industries, worked together for over a year to create Open Source Compass. Free, easy to use and publicly available, the tool enables users to access the research we conducted on technology domains, projects, programming languages and locations of interest. Users can explore technologies, run comparisons, and share and download data through Q1 2019.

Our goal is to provide actionable insights to help business leaders scout for new technologies and identify innovation opportunities, detect potential risks, and provide insights into talent. The site also assists startups and developers in evaluating tools and assessing the competitive landscape, as well as helps students students and faculty developing projects with open source software.

A snapshot of questions the site can help answer includes:

  • Which technology domains are growing and where is development happening?
  • Which projects are seeing the largest adoption over the past quarter?
  • How is a project related to other projects in terms of common contributors?
  • Which licenses are commonly used?
  • Which programming languages are driving growth in a specific domain?
  • Who are the most active developers by programming language?
  • Where are the clusters of development around the world by domain?

Open source technology is fast becoming an accelerator for digital transformation, value creation and talent strategy. Open Source Compass is a powerful new tool with advanced analytics and visualization capabilities that brings it into perspective.
