Edge.js logo

Run JavaScript anywhere. Safely.

Edge.js is a secure JavaScript runtime, designed for Edge computing and AI workloads.

Edge.js uses WebAssembly for sandboxing when in --safe mode, so even the most insecure programs can run on it safely. Edge also is:

• ✅ Fully compatible with Node.js.
• 🔒 Sandboxed by design.
• 🧩 Pluggable with any JS engine: V8, JavaScriptCore or QuickJS.
• 💪 Compatible with any package manager: NPM/PNPM/Yarn/Bun.

curl -fsSL https://edgejs.org/install | bash

You can use it as you would do it with Node.js:

const http = require("node:http");
http
 .createServer((_req, res) => {
 res.end("hello from edge\n");
 })
 .listen(3000, () => {
 console.log("listening on http://localhost:3000");
 });

$ edge server.js

If you want to use it in your current workflow, just wrap your commands with edge:

$ edge node myfile.js
$ edge npm install
$ edge pnpm run dev

First, clone the repo and initialize only the napi submodule:

git clone --recurse-submodules https://github.com/wasmerio/edgejs.git
cd edgejs

Build the CLI locally:

make build
./build-edge/edge server.js

./build-edge/edge --run dev

Or run the tests:

make test
NODE_TEST_RUNNER="$(pwd)/build-edge/edge" \
./test/nodejs_test_harness --category=node:assert

We have created a public ROADMAP, so you can contribute into the project easily!

• 0.x Production readiness: platform coverage across Linux, Windows, macOS, iOS, and Android; reliability in constrained environments; security audits; and successful real production use.
• 1.x Need for speed: faster startup, faster core paths, and performance that competes with or beats Node.js, Bun, and Deno on most workloads.
• 2.x Enhancements: first-class TypeScript support and a smoother developer experience.
