Wasmer is a high-performance WebAssembly runtime that runs lightweight, secure, sandboxed containers anywhere from desktops to cloud, edge, and browsers. It supports WASI and WASIX out of the box and offers embeddable SDKs for multiple languages including Rust, Go, Python, PHP, and JavaScript.

Use cases

• run webassembly binaries as lightweight containers
• sandbox untrusted code with no file or network access by default
• embed a wasm runtime in go, python, php, or javascript applications
• run cli tools and server apps on any platform without recompiling
• deploy websites and apps to the edge with millisecond cold starts
• run wasi and wasix programs at near-native speed

When to choose

• you need a fast, secure wasm runtime with broad platform support
• you want lightweight container-like sandboxing without docker
• you need to embed wasm execution into another language via an SDK
• you want to run the same binary across desktop, cloud, edge, and browser

When to avoid

• you need full Linux container compatibility with arbitrary syscalls
• your workload depends on native libraries or hardware not exposed via WASI
• you need mature orchestration features like Kubernetes integration
