New Contributors Closing Issues

Question: How many contributors are closing issues for the first time in a given project?


This metric is an indication of the volume of contributors who are closing issues for their first time within a given project. When a contributor closes an issue for the first time it is some indication of "stickiness" of the individual within that project, especially for contributors who are not also committers.


To know how contributors are moving through the contributor funnel by identifying “closing issues” as a milestone in the contributor journey.

  • Count. Total number of contributors closing issues on this project for the first time during a given time period.
  • Percentage. Proportion of contributors closing issues on this project for the first time during a given time period, computed against all contributors having closed issues on this project during the same time period.


  • Period of time. Start and finish date of the period during which new issue closers are counted. Default: forever (i.e., the entire observable project lifetime)


  • Exclude reopened issues (optionally, filter if reopened in less than 1 hour)


  • Table with names of contributors who closed an issue for the first time and when that was.
  • Timeline showing the time on the x-axis, and the aggregated metric value on the y-axis for fixed consecutive periods of time (e.g. on a monthly basis). This visualisation allows to show how the metric is evolving over time for the considered project.
