Real Linux that boots in milliseconds. A full TCP/IP stack with inbound and outbound HTTPS, a real shell, and real tools — no install, no container, no cloud VM.
A genuine Linux userland running in a WebAssembly VM, right in the tab. Run bash, edit files, compile code, and manage processes — nothing to download and nothing to set up.
A full TCP/IP stack with outbound and inbound HTTPS. curl public APIs, git clone repositories, npm i packages, and expose servers running inside the VM.
Snapshot restore brings the machine up in under a second. Share a link and the recipient lands in a warm, ready-to-use dev environment — no cold-start, no provisioning wait.
Boot VMs, attach terminals, mount repositories, forward ports, and inject secrets — all from a small JavaScript SDK. The same engine that powers this site powers your product.
import { WebContainer } from '@webvm/sdk' // boot a real Linux machine in the tab const vm = await WebContainer.boot() // spawn a shell and stream its output const sh = await vm.spawn('/bin/ash', ['-l']) sh.output.pipeTo( new WritableStream({ write(chunk) { terminal.write(chunk) } }) ) // real networking, inbound + outbound HTTPS await vm.spawn('npm', ['install'])
WebVM powers the environments behind AI coding tools, cloud IDEs, API sandboxes, and developer education — a full dev experience in a single link.
Give your agent a real Linux shell: run tests, edit files, hit APIs, and hand back a shareable sandbox URL.
Replace fragile Docker onboarding with disposable, reproducible web VMs wired to your repos and tooling.
Turn docs into real backends. Let users call your API from a secure VM with your SDKs preinstalled.
One-click Linux for workshops and courses. Reset in seconds, no installs, identical for every learner.
