Metric definitions
Every figure this site publishes is defined here once: what it measures, over what period, from which source, and the specific ways it misleads. Nothing is displayed anywhere on the site that does not have an entry on this page.
| Figure | Group | Period it carries | In one sentence |
|---|---|---|---|
| Developer Commit Count | Development | trailing 30 days | How many code changes were published to the project's public repositories in the last month. |
| Active Developer Count | Development | trailing 30 days | How many distinct people contributed code to the project's public repositories recently. |
| Repository Stars and Forks | Development | point-in-time | How many people have bookmarked or copied the project's public code repository. |
| Repository forks | Development | point-in-time | How many copies of the project's public code repository other developers have made. |
| Pull requests merged | Development | since repository creation | How many proposed code changes have been reviewed and accepted into the project's public repository over its lifetime. |
There are also 8 figures a reader may expect that we deliberately do not publish, because no source we use provides them in a form we would stand behind.
