A Genymotion alternative: Android in a browser, shared by link
Genymotion is a fine emulator — for the person running it. The moment you need someone else to see your app, an emulator instance becomes homework you assign to your client. PreviewAPK takes the other shape: the session lives in the browser, and all you send is a link.

What Genymotion does well
Genymotion has been a developer staple for years, on desktop and in the cloud, and it earns that in specific areas:
- Root and low-level control. Rooted instances, custom configurations, and the knobs developers need for systems-level work and debugging.
- Sensor and environment simulation. GPS, battery, network conditions, and other simulated inputs for testing how an app behaves — not just how it looks.
- A local development loop. A desktop emulator that sits next to your IDE, ready for your own daily debugging.
If your testing involves root, sensors, or deep configuration, stay with Genymotion — PreviewAPK deliberately offers none of that. The tools diverge at a different question: who else needs to see the app?
The real difference: instances vs links
An emulator is a machine you operate. Sharing one means the other person operates it too — installing software, provisioning an instance, waiting for a boot, on their hardware or their cloud account. Every reviewer repeats the setup, and every "it doesn't work on my machine" becomes your support ticket.
A PreviewAPK session inverts that. You upload an APK once; a real Android device boots in the cloud in seconds with your app installed and launched; and the session gets a share link. Your client, tester, or teammate opens it in a browser and the app is simply there — one person drives, others watch live, and nobody installed anything. Sessions auto-stop after 15 minutes of inactivity, so shared devices never idle on your bill.
There's also a middle step emulators can't offer: from the portal, the owner can mint a short-lived install link (QR) for their own phone and install the exact same APK — real hardware, no app store, no test-flight-style enrollment. Share links never serve files.
Genymotion vs PreviewAPK, side by side
| Genymotion | PreviewAPK | |
|---|---|---|
| Runs where | Your desktop, or cloud instances you operate | Cloud device, streamed to any browser |
| Sharing | Others need their own setup/instance | Session link per run — view-only, dies when the session ends; viewers need nothing |
| Android versions | Wide range of emulator images | Android 10–15, set on the device |
| Pricing shape | Per user (desktop) / per instance (cloud) | Flat $19/mo per device, unlimited testing |
| Setup | Install, configure, provision images | Upload an APK — that's the setup |
| Root / low-level access | Yes — a core strength | No — standard device profiles |
| Agent MCP | No MCP server for AI agents | Hosted MCP endpoint — a URL and a key, nothing to install; 27 tools |
| Agent handoff | No | The agent can ask the human to do one step — a password, a 2FA code, a payment — in the portal, then resumes on its own |
| Run reports | No | A report card ends every agent run: what was tested, actions taken, errors — counted by the system |
How PreviewAPK works
- Upload your APK. Choose an Android version (10–15) and a Pixel 9 Pro or Galaxy S24 profile.
- A device boots in the cloud — in seconds — with your app installed and launched.
- Share the link. Anyone with it sees the live app. If it should also land on your own real phone, mint a short-lived install link (QR) from the portal — share links never serve files.
FAQ
Can I root a PreviewAPK device or change low-level settings like Genymotion?
No. Genymotion is the better tool for rooted devices, sensor simulation, and low-level configuration — it's built for developer control over the emulator. PreviewAPK devices are standard Android 10–15 profiles (Pixel 9 Pro, Galaxy S24) set up to run your app for preview and review, not for systems work.
Do people I share with need to install an emulator?
No. With PreviewAPK there is no instance for viewers to run at all: the app runs on a cloud device, and anyone opening the session's share link sees it live in their browser. One person drives; everyone else watches. Nothing is installed on either side.
Which Android versions does PreviewAPK run?
Android 10 through 15, on Pixel 9 Pro and Galaxy S24 device profiles. Version and profile are device settings, so you can check the same build across versions without maintaining emulator images for each.
How does pricing compare to Genymotion?
Genymotion pricing is per user or per cloud instance, reflecting that you're renting emulator capacity you operate yourself. PreviewAPK is a flat $19/month per device with unlimited testing — you pay for the app you share, not for instances, seats, or minutes.
