How a repository gets this Tag

An agent reads the description, the GitHub topics, and the start of the README of each repository. It chooses Tags only from the Tag list in the AwesomeRepos source code. For each Tag, it quotes the text. A code check keeps the Tag only when the quote is in that text. The page of each repository shows the quote of each of its Tags. A Tag does not rank repositories. It does not say that one repository can replace another. To report a wrong Tag, use "Report a problem with this page" on the page of the repository.

How the numbers are counted

All numbers come from the Star History of the repositories that have the Tag now. A period is a run of complete UTC days. All numbers on this page count only the repositories that AwesomeRepos shows in lists. A machine computes them each hour.

For each repository, a period counts only when Star History has each of its days, or when the repository was created in the period. Otherwise the table shows "–". The bars of a week with no complete data are grey.

The Pace is the net stars of a period divided by the net stars of the period before. It shows only when Star History covers each day of the period before, with at least 3 net stars a day on average.

The chart at the top adds up the net stars of all the repositories with the Tag. A rising Admission comes into the Repository Index because it gained stars quickly. Its Star History before its Admission comes from the Repository Host. Thus the days before many rising Admissions are higher than they were for the repositories in the index at that time.

The releases are the GitHub releases of each repository. The lists and the table do not rank repositories, and they do not say that one repository can replace another.
