Score: 76/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 97, release rhythm 35, longevity 100
- inputs: {"age_days": 3997, "days_push": 18, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## Adoption (not part of the score)
Stars 9432, forks 369 (observed 2026-08-28T04:10:31.161617+00:00)

## What it is
Star History is a web application and API that generates GitHub star history charts and rank badges for any repository. It supports embedding live charts and badges in READMEs and is also available as a Chrome extension.

## Use cases
- plot the star growth of a GitHub repo over time
- compare star history of multiple repositories
- embed a live star history chart in a README
- add a star history rank badge to my project
- track trending open source projects weekly
- view a star map of related repositories

## When to choose
- you want to visualize or compare GitHub repository popularity over time
- you need embeddable live charts or badges for project READMEs
- you want to discover trending open source projects

## When to avoid
- you need general GitHub analytics beyond stars, such as forks, issues, or traffic
- you need offline or private-repo analytics

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, charts, analytics
- domain: developer-tools, data-visualization, analytics, social-media
- platform: browser, browser-extension
- tags: github, star-history, open-source-metrics, embeddable-badges, chrome-extension, web-server, nodejs
