Product Overview
What is Wasmer?
Wasmer is a cutting-edge WebAssembly runtime designed to run applications securely and efficiently across diverse environments, including desktops, servers, browsers, mobile devices, and edge networks. It leverages WebAssembly to provide container-like isolation with near-native performance, supporting multiple compiler backends and broad language integrations. Wasmer simplifies scaling by enabling serverless deployment and offers a pluggable architecture for custom runtimes and backends. Its security model ensures sandboxed execution, making it ideal for running untrusted code safely.
Key Features
Multi-Backend Support
Supports multiple compiler backends such as Singlepass, Cranelift, LLVM, V8, Wasmi, and WAMR, allowing flexible trade-offs between compilation speed and runtime performance.
Cross-Platform Runtime
Runs WebAssembly applications seamlessly on various platforms including Windows, macOS, Linux, iOS, Android, browsers, and embedded systems.
Secure Sandboxed Execution
Executes applications in isolated environments by default, preventing unauthorized access to files, networks, or system resources unless explicitly permitted.
Serverless and Edge Ready
Enables effortless scaling with serverless deployment on the edge, offering instant cold starts and affordable pricing comparable to CDN costs.
Pluggable Architecture
Allows developers to plug in custom backends, compilers, or runners to tailor the runtime to specific needs.
Broad Language and ABI Support
Supports many programming languages and ABIs including WASI and Emscripten, facilitating easy integration with existing applications.
Use Cases
- Universal Application Deployment : Deploy any application across cloud, edge, desktop, and mobile environments without code changes.
