A WebAssembly-based AWS CLI that runs directly in the browser. The CLI is written in Rust, compiled to WASI Preview 2 components, and executed via a custom xterm.js terminal addon. A Chrome extension embeds the shell into any AWS Console page with automatic credential integration.

• Rust (stable, with wasm32-wasip2 target)
• cargo-component (via cargo bin)
• Node.js >= 24

# Load extension/ as unpacked extension in chrome://extensions
# Navigate to any AWS Console page — shell appears at the bottom

Node.js:

cd www/aws-cli/component && npm start

wasmtime (native):

cd packages/wasi-engine && cargo run -- s3 ls --region us-east-2 --no-sign-request s3://nara-national-archives-catalog/authority-records/organization/

The extension embeds the shell into AWS Console pages. It extracts the session's credentials — no API keys or manual login required.
