Healthy
Healthy: actively maintained by 16 people, no known risks.
Why
No rule fired.
What would change this
- Partly checked: maintenance (Commit counts are estimated: the commit sample stops before the window start, so GitHub's totals were scaled by the sampled bot share.; Authors in the last 90 days are counted from the sampled commits only.)
- A dormant maintenance status, a deprecated or archived package, a successor link, or a critical advisory would change this.

Bursts
- May 8, 2014 to May 13, 2014: about 284 more stars than usual, peak 124 in one day, a spike that tapers off. Outside explanation: a jump in forks.
- Aug 6, 2014 to Aug 8, 2014: about 82 more stars than usual, peak 39 in one day, a flat block of stars. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Mar 17, 2015 to Mar 21, 2015: about 445 more stars than usual, peak 179 in one day, a spike that tapers off. Outside explanation: a jump in forks.
- Jun 1, 2016 to Jun 2, 2016: about 87 more stars than usual, peak 67 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Dec 31, 2021 to Jan 3, 2022: about 112 more stars than usual, peak 71 in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained.
- May 12, 2022 to May 13, 2022: about 52 more stars than usual, peak 38 in one day, a spike that tapers off. Outside explanation: a jump in issues and pull requests.
- Mar 21, 2023 to Mar 23, 2023: about 78 more stars than usual, peak 58 in one day, a spike that tapers off. Outside explanation: a jump in issues and pull requests.
- 4 stars on a repo created before February 2013 have no date, so they aren't in the chart.
- 5 stars GitHub has since removed (tracked since Oct 13, 2026).
Anyone can buy stars for any repo; bursts alone don't prove the owner did.
- The star history looks organic.
- 4 stars on the creation day are undated (before 2013-02-10) and are not counted.
