shadcn/ui Cooling
On TutorHero's Everything Index, shadcn/ui is cooling on GitHub: 0.12 of every 10,000 new public repos over the last three months (116 a month), -56% vs a year ago. The 12-month forecast says easing (-23%). By the end of 2032, lines in the same state ended between 0.09x and 3.1x of where they started (median 0.66x).
Since 2019, and the range to 2032

The range is not a forecast of this line: it is what GitHub lines in the same state (lost more than 15% of its share in a year) did 1 to 5 years later, 2019 to 2026, applied to today's level. Past 5 years it is stretched, not measured. Checked out of time (learned before 2022, scored after), 71% of outcomes landed inside the 90% range, so read it as wide. Open it in the Everything chart.
Week by week
New public repos with the shadcn tag each week (Monday to Sunday, UTC). The outlined bars, last week included, are still filling in, as tags are often added days after a repo is created, so their height will grow a little. "Against the field" divides the change by what the typical tag did, so a wave that lifts every tag does not count. Hover for the numbers.
Built vs talked about
Each line is its own share (of all new GitHub repos, all Hacker News stories, all English Wikipedia views, all new stars on the repos we track), shown as a share of its own peak, so the timing and shape compare even though the units differ. Hover for the counts. Tap a name to hide or show a line.

Not investment advice. Measurements of what people build and star on GitHub, a statistical forecast, base rates and a model's reading of them. Nothing here is about any company's revenue, valuation or stock.
