Last year we published our first aggregated report on open source usage data on Scarf and since then we’ve been pleased to see Scarf data cited by others, whether discussing open source or advocating for it. This latest edition of The Scarf Report covers the quarterly numbers for Q4 2023, as well as 2023 in its entirety.
Overall Open Source Usage in Q4 and 2023

A few companies that consistently ranked in the Top 10 for OSS usage throughout the year, we observed:
- Apple
- Cisco
- Oracle
- Microsoft
- Disney
- IBM
With 94% of the Fortune 500 seen interacting with open source software tracked with Scarf in Q4 2023, data from Scarf serves as compelling and concrete evidence that open source is critical to enterprises globally. This is also further evidence that Scarf and approaches like it can uncover commercial open source usage that would otherwise go unreported.
Regional Usage of Open Source Software
Open source usage is global, but looking at the geographical statistics of Scarf downloads continues to show interesting results and trends. Significant growth in certain regions can be attributed to a number of potential factors: increased traction of Scarf itself, increased regional traction of particular projects that use Scarf, or increase in regional popularity of open source as a whole.

Container Registries
While Scarf tracks downloads of various artifact types, the most popular kind of artifact container images. Container downloads on Scarf have surfaced the rapid rise to prominence of GitHub Container Registry, but Docker Hub remains the dominant container registry by a wide margin, still receiving twice as much volume of pulls on Scarf.

Over the course of the year, the share of artifacts pulled through Scarf from Docker Hub has continued to increase, with its share of pulls increasing 16% between the first and last quarter of the year.

Our Takeaways
As large organizations in both the private and public sector increase their reliance on open source, opportunities for successful commercialization of open source software also becomes increasingly achievable. We are confident that this upward trajectory will foster innovation, growth, and expansion within the open source community.
