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-wasip1 $ rustc hello.rs --target wasm32-wasip1 $ wasmtime hello.wasm Hello, world! ``` (Note: make sure you installed Rust using the `rustup` method in the official instructions above, and do not have a copy of the Rust toolchain installed on your system in some other way as well (e.g. the system package manager). Otherwise, the `rustup target add...` command may not install the target for the correct copy of Rust.) ## Features * **Fast**. Wasmtime is built on the optimizing [Cranelift] code generator to quickly generate high-quality machine code either at runtime or ahead-of-time. Wasmtime is optimized for efficient instantiation, low-overhead calls between the embedder and wasm, and scalability of concurrent instances. * **[Secure]**. Wasmtime's development is strongly focused on correctness and security. Building on top of Rust's runtime safety guarantees, each Wasmtime feature goes through careful review and consideration via an [RFC process]. Once features are designed and implemented, they undergo 24/7 fuzzing donated by [Google's OSS Fuzz]. As features stabilize they become part of a [release][release policy], and when things go wrong we have a well-defined [security policy] in place to quickly mitigate and patch any issues. We follow best practices for defense-in-depth and integrate protections and mitigations for issues like Spectre. Finally, we're working to push the state-of-the-art by collaborating with academic researchers to formally verify critical parts of Wasmtime and Cranelift. * **[Configurable]**. Wasmtime uses sensible defaults, but can also be configured to provide more fine-grained control over things like CPU and memory consumption. Whether you want to run Wasmtime in a tiny environment or on massive servers with many concurrent instances, we've got you covered. * **[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.
