## Why it’s here

- Star-counter measurements on 2026-11-14 (UTC), 00:03–10:32: 3794 → 4129 stars (+335). This is the change over that interval.
- Estimated end-of-day forecast: about +1,022 stars, using observed gains and the previous day.
- Before this, the repository barely got any stars — about 0 per day.
- Elevated gains were measured on the last 2 completed UTC days in a row. Continued growth is not guaranteed.
- The repository is 19 days old and already has 4,129 stars.
- Top new repositories this month: #41.
- Hacker News: “UI SDK: A library for agents to build the next generation of UIs” — 7 points, 1 day ago.
- About 39 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
