GitHub repositories taking off in the last 90 days

Ranked by how many more stars each repo got in the last 90 days than its pace over the 90 days before would predict, lowest first. Star counts come from GitHub. Last updated 11 Nov 2026, 15:20 UTC.

How the ranking works

Stars gained: New stars in the window. "all" means the repo is younger than the window, so the number is every star it has.
Today: Stars since midnight US Pacific time, so a partial day.
Above pace: How many more stars the repo got than its pace in the window before would predict. +500 means 500 more than usual.
Momentum: A daily score: 8 points per star and 2 per fork since midnight UTC, reduced for repos that are this busy every day.
Speed-up: Stars per day in the window divided by stars per day in the window before. "New" means the repo is younger than the window. "Under 14 days" (twice the window; "Under 2 years" for 1 year) means it is older than the window but too young for a full window before it to compare with.
Suspected: Repositories with at least 50 stars are left out as likely bought stars when they have no detected programming language and got those stars within a day of being created; or got them within 14 days while having no watchers, at most 1 fork, no detected language or under 1 KB of code other than HTML and CSS, and either 5 KB or less of files or an owner that is a personal account with at most 1 follower. Repositories with no detected language are also left out when, at any age, they have 5 KB or less of files and got at least 90% of their stars on a single day that ended more than a day ago; or have 5 KB or less of files and belong to a personal account with no followers that was created at most an hour before the repository. Any repository with at least 50 stars is also left out when, under 3 days old, it has no watchers and at least 5 forks and belongs to a personal account with no followers; it stays out while that account has no followers. Some repositories are also left out, or kept in, by hand after a review of the daily lists, whatever the rules above say. See them.
Bars: Stars per day (per week for 90 days and 1 year). Bright bars are the selected window. Heights use a square-root scale, so quieter days stay visible next to a spike.
