In August we shared both CNCF’s project velocity as well as the top 30 highest open source projects in 2020. Our goal is to share this information every six months moving forward. Providing insight into the projects with the highest developer velocity give a good indication into which areas are taking off and which platforms are likely to be successful in the coming months and years. 

Note that: Rather than debate whether to measure them via commits, authors, or comments and pull requests, we use bubble charts to show all three axes of data, and plot on a log-log chart to show the data across large scales. In the graphs, the bubbles’ area is proportional to the number of authors, the y-axis (height) is the total number of pull requests & issues, and the x-axis is the number of commits.

Here are the main takeaways I see from these charts:

You can find all the current and past reports on GitHub, as well as a list and charts on the Google sheets below:
