Healthy Actively maintained by 12 people, no known risks. ## Why No warning signs: none of the [verdict rules](https://reporadar.ai/methodology) applied to this repo. ### 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.; Only 1 recent issues can be checked for a response, too few to measure response time.) - A dormant maintenance status, a deprecated or archived package, a successor link, or a critical advisory would change this. ## Maintenance Partial Active **Human commits, 30 days** 445 **Human commits, 90 days** 1.9k **Human commits, 365 days** 1.9k **Bot share of commits, 365 days** 0% **Last commit** Nov 11, 2026 (17 hours ago) **Last human commit** Nov 11, 2026 (17 hours ago) **Authors, 90 days** 12 **Last release** Oct 20, 2026 (23 days ago) **Median PR merge time** 44 hours Too few recent issues to measure responsiveness. - 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. - Only 1 recent issues can be checked for a response, too few to measure response time.

Red bars overlap a burst. ### Bursts - **Oct 17, 2026 to Oct 19, 2026**: about 477 more stars than usual, peak 183 in one day, a shape we can't classify. Outside explanation: a Hacker News post. Anyone can buy stars for any repo; bursts alone don't prove the owner did. - Not enough star history yet to judge the star count. - Star history from the full report of Oct 20, 2026; this update did not re-read it.
