## Useful for

- Build a 2D game in Rust by running the breakout example via cargo run --example breakout
- Create a windowed app with Bevy by adding DefaultPlugins
- Study the engine's examples to learn the ECS approach

## Why it’s here

- Star-counter measurements on 2026-10-21 (UTC), 00:08–21:57: 49163 → 49188 stars (+25). This is the change over that interval.
- Estimated end-of-day forecast: about +27 stars, using observed gains and the previous day.
- Interest is fading: the two-day pace is 59% of the previous week and a half.
- Hacker News: “Bevy 0.20” — 256 points, 12 days ago.
- Recent forks include notable developers: @ErikHellman (638 followers).

## Star trust

Star growth looks organic.

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

## Numbers

- Forks: 4,954
- Issues and pull requests: 24,196
- Watchers: 327
- Average over the last week: 30 per day
- Usual pace: 38 per day
- Latest release: v0.20.0 (2026-10-08)

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.
