Linux and macOS with a small install\nscript:\n\n```sh\n$ curl https://wasmtime.dev/install.sh -sSf | bash\n```\n\nWindows or otherwise interested users can download installers and\nbinaries directly from the [GitHub\nReleases](https://github.com/bytecodealliance/wasmtime/releases) page.\n\n## Example\n\nIf you've got the [Rust compiler\ninstalled](https://www.rust-lang.org/tools/install) then you can take some Rust\nsource code:\n\n```rust\nfn main() {\n    println!(\"Hello, world!\");\n}\n```\n\nand compile/run it with:\n\n```sh\n$ rustup target add wasm32-wasi\n$ rustc hello.rs --target wasm32-wasi\n$ wasmtime hello.wasm\nHello, world!\n```\n\n## Features\n\n* **Lightweight**. Wasmtime is a standalone runtime for WebAssembly that scales\n  with your needs. It fits on tiny chips as well as makes use of huge servers.\n  Wasmtime can be [embedded] into almost any application too.\n\n* **Fast**. Wasmtime is built on the optimizing [Cranelift] code generator to\n  quickly generate high-quality machine code at runtime.\n\n* **Configurable**. Whether you need to precompile your wasm ahead of time,\n  or interpret it at runtime, Wasmtime has you covered for all your\n  wasm-executing needs.\n\n* **WASI**. Wasmtime supports a rich set of APIs for interacting with the host\n  environment through the [WASI standard](https://wasi.dev).\n\n* **Standards Compliant**. Wasmtime passes the [official WebAssembly test\n  suite](https://github.com/WebAssembly/testsuite), implements the [official C\n  API of wasm](https://github.com/WebAssembly/wasm-c-api), and implements\n  [future proposals to WebAssembly](https://github.com/WebAssembly/proposals) as\n  well. Wasmtime developers are intimately engaged with the WebAssembly\n  standards process all along the way too.\n\n[Cranelift]: https://github.com/bytecodealliance/wasmtime/blob/main/cranelift/README.md\n[embedded]: https://bytecodealliance.github.io/wasmtime/lang.html\n\n## Language Support\n\nYou can use Wasmtime from a variety of different languages through embeddings of\nthe implementation:\n\n* **[Rust]** - the [`wasmtime` crate]\n* **[C]** - the [`wasm.h`, `wasi.h`, and `wasmtime.h` headers][c-headers] or use [`wasmtime` Conan package]\n* **[C++]** - the [`wasmtime-cpp` repository][wasmtime-cpp] or use [`wasmtime-cpp` Conan package]\n* **[Python]** - the [`wasmtime` PyPI package]\n* **[.NET]** - the [`Wasmtime` NuGet package]\n* **[Go]** - the [`wasmtime-go` repository]\n\n[Rust]: https://bytecodealliance.github.io/wasmtime/lang-rust.html\n[C]: https://bytecodealliance.github.io/wasmtime/examples-c-embed.html\n[`wasmtime` crate]: https://crates.io/crates/wasmtime\n[c-headers]: https://bytecodealliance.github.io/wasmtime/c-api/\n[Python]: https://bytecodealliance.github.io/wasmtime/lang-python.html\n[`wasmtime` PyPI package]: https://pypi.org/project/wasmtime/\n[.NET]: https://bytecodealliance.github.io/wasmtime/lang-dotnet.html\n[`Wasmtime` NuGet package]: https://www.nuget.org/packages/Wasmtime\n[Go]: https://bytecodealliance.github.io/wasmtime/lang-go.html\n[`wasmtime-go` repository]: https://pkg.go.dev/github.com/bytecodealliance/wasmtime-go\n[wasmtime-cpp]: https://github.com/bytecodealliance/wasmtime-cpp\n[`wasmtime` Conan package]: https://conan.io/center/wasmtime\n[`wasmtime-cpp` Conan package]: https://conan.io/center/wasmtime-cpp\n\n## Documentation\n\n[📚 Read the Wasmtime guide here! 📚][guide]\n\nThe [wasmtime guide][guide] is the best starting point to learn about what\nWasmtime can do for you or help answer your questions about Wasmtime.
