About:
Wasmer is a lightweight, fast WebAssembly runtime that enables running Wasm applications efficiently on any platform. It provides a secure sandbox environment for executing code, making it ideal for serverless functions, edge computing, and plugin systems. Wasmer supports multiple programming languages and integrates seamlessly with existing infrastructure.
Key Features:
  • Universal runtime for WebAssembly modules
  • High performance with near-native speed
  • Secure sandboxing and isolation
  • Multi-language support (Rust, C, Python, etc.)
  • CLI tools for easy management
Use Cases:
  • Running serverless WebAssembly functions
  • Building secure plugin systems for applications
  • Deploying portable microservices at the edge
  • Embedding Wasm modules in existing applications
Alternatives:
  • wasmtime – Similar performance, but Wasmer offers broader language integrations
  • node.js – Heavier runtime; Wasmer provides better isolation and portability
