Wasmer

Wasmerとは？

Wasmer is a WebAssembly platform for running applications in lightweight sandboxes on your own infrastructure or in the cloud. It combines Wasmer Runtime for local and embedded execution, a registry of runnable software packages, and Wasmer Edge for serverless deployment.

Developers can run packaged tools, embed the runtime in applications, or deploy websites and services without maintaining servers. WASIX powers the package ecosystem, while Edge provides framework templates and a global network for hosting applications.

Wasmerでできること

Embeddable runtime

Use SDKs for Rust, Python, JavaScript, Go, Ruby, and C to integrate WebAssembly execution into existing applications. The runtime supports server, browser, and mobile environments.

Execution metering

Set an instruction limit to stop a program deterministically after a specified amount of execution, giving hosts control over sandbox resource consumption.

Pluggable execution architecture

Choose compiler backends such as Singlepass, LLVM, and Cranelift, or create custom runners. Supported runner options include WASI, WCGI, and Emscripten.

Runnable software registry

Access packaged tools including Bash, Python, PHP, SQLite, curl, and FFmpeg. The registry provides ready-to-run software for the Wasmer environment.

Serverless application hosting

Wasmer Edge hosts applications across 12 global regions. Hobby supports web applications; Pro adds TCP/UDP application support and SSH/SFTP access.

Repository deployment workflow

Import a repository and use automatic CI/CD for deployments. Templates cover frameworks and applications including WordPress, Django, Next.js, Laravel, and Hugo.

利用シーン

“Run development tools locally”

Use the CLI to execute registry packages such as jq, curl, or Python on a development machine, starting with the installation command and a package to run.

“Host websites and web applications”

Launch a WordPress site, static website, or framework application on Edge. Connect a custom domain and choose a plan based on traffic, compute usage, and collaboration needs.

“Add controlled execution to an application”

Embed Wasmer in a desktop, mobile, or server application to execute WebAssembly programs with sandboxing and instruction limits. Headless mode supports deployments that need a smaller runtime.
