+We are happy to announce the [Uutils playground](/playground) - an interactive terminal that lets you run real Rust Uutils Coreutils directly in your browser, with no installation, no server, and no network round-trips after the initial page load.
 
 Just open the page and start typing commands like `ls`, `sort`, `cat`, `head`, `factor`, or any of the 60+ utilities available. You can pipe commands together (`sort fruits.txt | uniq -c | sort -rn`), use redirections (`echo hello > file.txt`, `cat < file.txt`), explore the virtual filesystem, and even switch between 30+ languages using the locale dropdown.
 
 ### How it works
 
-The uutils coreutils are compiled to WebAssembly (targeting `wasm32-wasip1`) as a single multicall binary - similar to BusyBox. When you type a command, a minimal JavaScript shell parses your input, sets up pipes between stages, and executes each one by instantiating the WASM binary with the right arguments. A virtual in-memory filesystem backed by [browser_wasi_shim](https://github.com/bjorn3/browser_wasi_shim) provides file I/O. Everything runs client-side - once loaded, the playground works entirely offline.

 An important distinction worth noting: **coreutils only provides individual commands** (`sort`, `cat`, `ls`, etc.). Features like `if`/`then`/`else`, `while` loops, variable expansion (`$VAR`), and globbing (`*.txt`) are shell features provided by Bash, Zsh, or similar - not by coreutils. The playground's JavaScript shell is intentionally minimal, keeping the focus on the coreutils themselves.

 We are actively working on adding more commands as we improve WASI compatibility in uutils coreutils.
