Wasmer is a high‑performance WebAssembly runtime that provides fast, secure sandboxes for running applications. It can be used via a CLI, embedded SDKs for multiple languages, or directly in the browser.
Use cases
- run Python or Node.js scripts in an isolated WebAssembly sandbox
- embed a WebAssembly sandbox into a Rust, Go, or Python application
- execute untrusted code safely on a serverless edge platform
- test compiled binaries without installing full toolchains
- deploy lightweight micro‑VMs for AI agents or serverless functions
When to choose
- you need fast startup and low memory overhead for WebAssembly workloads
- you require fine‑grained control over file, network, and environment access
- you want a single runtime that works on desktop, server, and in the browser
- you are building AI agents or serverless functions that benefit from sandbox isolation
When to avoid
- your workload relies on native system calls not supported by WASI
- you need a full operating system VM rather than a lightweight sandbox
- you require deep integration with GPU drivers that are not yet exposed to Wasmer
