Linux virtualization in WebAssembly.
WebVM is a server-less virtual environment running fully client-side in HTML5/WebAssembly. It's designed to be Linux ABI-compatible. It runs an unmodified Debian distribution including many native development toolchains.
WebVM is powered by the CheerpX virtualization engine, and enables safe, sandboxed client-side execution of x86 binaries on any browser. CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator.
Spin is a framework for building and running event-driven microservice applications with WebAssembly (Wasm) components.
Spin is the open source developer tool for building and running serverless applications powered by WebAssembly.
A standard library for JavaScript and Node.js.
JavaScript to WASM compiler.
Jawsm (pronounced like "awesome") is a JavaScript to WebAssembly compiler written in Rust. It is similar to porffor in a way it also results in a standalone WASM binary that can be executed without an interpreter, but it takes a different implementation approach.
an open source, serverless framework for building intelligent functions and APIs, powered by WebAssembly.
You write your app logic in Go or AssemblyScript, and Modus provides additional features to easily integrate models, data, and external services.
Embeddable Postgres. Run a full Postgres database locally in WASM with reactivity and live sync. Lightweight WASM Postgres with real-time, reactive bindings.
PGlite is a WASM Postgres build packaged into a TypeScript client library that enables you to run Postgres in the browser, Node.js, Bun and Deno, with no need to install any other dependencies. It is only 3mb gzipped and has support for many Postgres extensions, including pgvector.
🚀 The leading Wasm Runtime supporting WASIX, WASI and Emscripten.
Wasmer is a blazing fast and secure WebAssembly runtime that enables incredibly lightweight containers to run anywhere: from Desktop to the Cloud, Edge and your browser.
the edge computing platform for developers. The open source platform offering a set of edge computing services.
Google Analytics, AB Tasty, Amplitude, Piano Analytics… can now run at the edge without being blocked or requiring user consent.
PyScript is an open source platform for Python in the browser.
PyScript is a framework that allows users to create rich Python applications in the browser using HTML's interface and the power of Pyodide, MicroPython and WASM, and modern web technologies.
A from-scratch experimental ahead-of-time JS engine
Porffor is a unique JS engine/compiler/runtime, compiling JS code to WebAssembly or native ahead-of-time.
It is limited for now; intended for research, not serious use!
Pixi is a package management tool for developers. It allows the developer to install libraries and applications in a reproducible way. Use pixi cross-platform, on Windows, Mac and Linux.
pixi is a cross-platform, multi-language package manager and workflow tool built on the foundation of the conda ecosystem. It provides developers with an exceptional experience similar to popular package managers like cargo or yarn, but for any language.
Hyper-efficient serverless on Kubernetes, powered by WebAssembly.
SpinKube is an open source project that streamlines developing, deploying and operating WebAssembly workloads in Kubernetes - resulting in delivering smaller, more portable applications and incredible compute performance benefits.
Lightweight Postgres packaged as WASM into a TypeScript library for the browser, Node.js, Bun and Deno.
PGlite is a WASM Postgres build packaged into a TypeScript client library that enables you to run Postgres in the browser, Node.js and Bun, with no need to install any other dependencies. It is only 3.7mb gzipped.
Universal Web App Server.
NGINX Unit is a lightweight and versatile application runtime that provides the essential components for your web application as a single open-source server: running application code (including WebAssembly), serving static assets, handling TLS and request routing.
The Universal Plug-in System. make all software programmable. Extend from within. Extend anything with WebAssembly (wasm).
