## Installation
The Wasmtime CLI can be installed on Linux and macOS with a small install
script:
```sh
$ curl https://wasmtime.dev/install.sh -sSf | bash
```
Windows or otherwise interested users can download installers and
binaries directly from the [GitHub
Releases](https://github.com/bytecodealliance/wasmtime/releases) page.
## Example
If you've got the [Rust compiler
installed](https://www.rust-lang.org/tools/install) then you can take some Rust
source code:
```rust
fn main() {
println!("Hello, world!");
}
```
and compile/run it with:
```sh
$ rustup target add wasm32-wasi
$ rustc hello.rs --target wasm32-wasi
$ wasmtime hello.wasm
Hello, world!
```
## Features
* **Lightweight**. Wasmtime is a standalone runtime for WebAssembly that scales
with your needs. It fits on tiny chips as well as makes use of huge servers.
Wasmtime can be [embedded] into almost any application too.
* **Fast**. Wasmtime is built on the optimizing [Cranelift] code generator to
quickly generate high-quality machine code at runtime.
* **Configurable**. Whether you need to precompile your wasm ahead of time,
or interpret it at runtime, Wasmtime has you covered for all your
wasm-executing needs.
* **WASI**. Wasmtime supports a rich set of APIs for interacting with the host
environment through the [WASI standard](https://wasi.dev).
* **Standards Compliant**. Wasmtime passes the [official WebAssembly test
suite](https://github.com/WebAssembly/testsuite), implements the [official C
API of wasm](https://github.com/WebAssembly/wasm-c-api), and implements
[future proposals to WebAssembly](https://github.com/WebAssembly/proposals) as
well. Wasmtime developers are intimately engaged with the WebAssembly
standards process all along the way too.

## Language Support
You can use Wasmtime from a variety of different languages through embeddings of
the implementation:
* **[Rust]** - the [`wasmtime` crate]
* **[C]** - the [`wasm.h`, `wasi.h`, and `wasmtime.h` headers][c-headers] or use [`wasmtime` Conan package]
* **[C++]** - the [`wasmtime-cpp` repository][wasmtime-cpp] or use [`wasmtime-cpp` Conan package]
* **[Python]** - the [`wasmtime` PyPI package]
* **[.NET]** - the [`Wasmtime` NuGet package]
* **[Go]** - the [`wasmtime-go` repository]
