# aws/aws-emulator

> A local AWS API emulator written in Rust: it serves an endpoint on your machine so you can test code without real AWS or an account. Supports server mode (CLI and any SDK) and an embedded mode for Rust tests.

## Useful for

- Run AWS SDK integration tests in CI without real cloud resources
- Start the emulator in Docker and point the AWS CLI at the local endpoint
- Embed the emulator in Rust tests as a dev-dependency for isolated instances

## Why it’s here

- Star-counter measurements on 2026-11-14 (UTC), 00:03–10:32: 7132 → 7643 stars (+511). This is the change over that interval.
- Estimated end-of-day forecast: about +1,305 stars, using observed gains and the previous day.
- Over the last two days the pace is 5.4× that of the previous week and a half.
- Elevated gains were measured on the last 3 completed UTC days in a row. Continued growth is not guaranteed.
- Hacker News: “AWS Finally Built Its Own AWS Emulator” — 986 points, 2 days ago.
- About 71 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.

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.
