### What we like

Local, single (Rust) binary that emulates AWS APIs. Can easily point the CLI and SDKs at it. Supports being embedded for isolated test instances. Includes agent skills and can run as a server.

### Tradeoffs

Doesn’t have full fidelity with all AWS APIs and it’s not easy to find out, but you can ask your AI agent to check for you.
