Your Android apps, live in the browser.
Upload an APK and get a real, interactive emulator streaming in any browser tab - no install, no SDK, no device lab. Then put it anywhere with one iframe.
CalCal · built & demoed on Emutize
Measured on our production box, not a brochure
From APK to a device you can touch
Outcomes, not infrastructure
What you get out of it
Emulators are the machinery. This is what actually changes for you the day you plug Emutize in.
Demos people actually open
Send a link instead of an APK. Investors, clients, and testers are inside your app in seconds - nothing to install, nothing to trust.
Bug reports you can reproduce
Every session is a factory-fresh device. "Works on my phone" stops being an argument - everyone tests on the same clean slate.
Previews inside your product
Your users see their app running while they build it. The preview pane is an iframe; the lifecycle is two API calls.
No device lab, ever
No racks of phones, no emulator snowflakes on laptops, no "whose machine has the SDK". One Linux box serves the whole team.
Under the hood, in one breath
How it works
Upload an APK
From the dashboard or one API call. The build sits in your library, ready to boot on demand.
A device boots for you
A fresh, isolated Android container starts in seconds, installs your app, and launches it automatically.
Interact anywhere
The screen streams to any browser; taps, swipes, and typing flow back. End it, and the whole device evaporates.
The feature list
Everything a hand on the device could do
Built API-first: the dashboard is just a customer of the same endpoints you get.
Live streaming player
Server-push JPEG streaming today, H.264/WebCodecs on the roadmap. Click-to-tap, drag-to-swipe, typing, hardware keys.
Embed SDK
Emutize.embed() drops a session into any page and emits ready/ended events, with remote-control calls from your UI.
Capability links
Session URLs carry their own token and die with the session. Viewers never need an account.
Service API
Create, inspect, and destroy sessions with Bearer-key REST from your backend. Sessions auto-reap after 15 idle minutes.
True isolation
One container per session, destroyed on release. No data survives - by design, not by cleanup script.
Your infrastructure
Runs on plain Linux boxes you control. Scale capacity by adding boxes, not by reading a pricing page.
Where it earns its keep
Use cases
Who this is for
Built by an app studio, for app studios
Emutize runs the portfolio it was born in - every screenshot on this site is our own apps on our own devices.
Indie studios
Demo every app in your portfolio from one box, without maintaining demo devices.
Builder platforms
The embed API was designed for "preview pane next to the editor" as the first-class customer.
QA & support teams
Clean-slate reproduction machines on demand, shareable as links.
Agencies
Client approvals without TestFlight/Play invites: a link that just opens the build.

This snippet is live against production - the embed guide has the full flow.
// 1. Your backend: create a session for an uploaded app
const r = await fetch("https://app.emutize.com/api/v1/sessions/", {
method: "POST",
headers: { "Authorization": "Bearer " + EMUTIZE_KEY, "Content-Type": "application/json" },
body: JSON.stringify({ app: "MyApp" })
});
const { embed_url } = await r.json();
// 2. Your frontend: drop it in
Emutize.embed("#preview", { embedUrl: embed_url })
.on("ready", () => console.log("device is live"));See your app in a browser tab today
