The XDA piece on running an AI agent to control an Android phone from a browser put a spotlight on a category that has been quietly maturing: apps that let you drive an Android device from a desktop web tab. Whether the driver is a person on a laptop, a local LLM running on a homelab, or a script in a browser console, the phone side needs an app that exposes screen mirroring, input events, or a full remote-control interface. These are the seven Android apps we tested for exactly that.
What to look for in a browser-to-Android control app
Not every “remote control” app is a fit here. A serious pick should:
- Expose a browser-reachable interface, not just a companion desktop app.
- Cover screen mirroring and input events, so you can see and control at the same time.
- Work over LAN without cloud round-trips, since cloud latency kills usability.
- Not require root for the primary use case.
- Handle files, notifications, or clipboard as a bonus.
- Respect Android’s storage and accessibility permissions rather than dodging them.
The seven picks below meet at least four. The strongest three meet all six.
Quick comparison
| App | Best for | Access method | Requires PC app | Free plan | Starting price |

| AirDroid | Web-first remote control | Browser | No | Yes | $2.99/mo |
| Vysor | Chrome-based mirror | Browser (Chrome only) | No | Yes | $2.50/mo |

The apps
1. Termux, best web server on Android
Termux is a full Linux userland on Android. Pair it with termux-api and termux-http-server (or run python -m http.server) and the phone becomes a device you drive from any desktop browser on the LAN. Combine with an AI agent script and it is exactly the setup XDA described: the browser tells the phone what to do, and the phone answers.
Where it falls short: No screen mirroring or input events out of the box; you script what you want. Recent Play Store versions of Termux are outdated; F-Droid or GitHub is the recommended install source. First-time setup takes reading.
Pricing:
- Free: full environment
- Paid: none
Platforms: Android
Bottom line: Best pick when the browser is your control surface and you plan to script what the phone does.
2. scrcpy, best screen mirror plus input
scrcpy is the open-source tool that mirrors an Android screen to a desktop over ADB and forwards keyboard and mouse input back to the phone. There is no Android app to install; scrcpy uses the ADB debugging channel the phone already speaks. Add scrcpy-web and you can watch the stream in a browser tab as well.
Where it falls short: Requires enabling USB debugging and, for over-Wi-Fi use, a one-time USB tether. Not “install and open” from the phone side. Some phone vendors delay ADB events by 100 ms or more, which is felt during typing.
Pricing:
- Free: full tool, no ads
- Paid: none
Platforms: Windows, macOS, Linux (companion), Android (no app needed)
Download: scrcpy releases
Bottom line: Best pick for the “type on my desktop, see it on my phone” workflow.
3. KDE Connect, best for file and notification sync
KDE Connect links an Android device to a desktop (Linux, Windows, macOS) over the LAN. It forwards notifications, mirrors clipboard, shares files, and lets the desktop trigger phone actions like “find my phone” or “run a command.” A browser plugin (KDE Connect Chrome Extension) extends the reach into Chrome/Firefox for tab-sharing.
Where it falls short: Not a full mirror; scrcpy is still the pick for that. Some features require the desktop app running in the background. iOS support does not exist.
Pricing:
- Free: full app
- Paid: none
Platforms: Android + desktop (Windows/macOS/Linux) + browser extension
Bottom line: Best pick when you want a bridge between phone and desktop but do not need full mirroring.
4. AirDroid, best web-first remote control
AirDroid was the original “control your Android from a browser” app and remains the friendliest. Open a browser tab, log in, and you get file transfer, SMS from the desktop, notification mirroring, and a screen-mirror pane (paid tier). No ADB, no companion desktop app, no root.
Where it falls short: The free tier caps mirroring and transfer speeds. The paid tier is $2.99/mo but adds real value only for heavy users. Data traverses AirDroid’s servers unless you enable LAN mode.
Pricing:
- Free: file transfer, notification mirror, limited SMS
- Paid: Premium at $2.99/mo unlocks screen mirror and remote camera
Platforms: Android + any browser
Bottom line: Best pick when you want browser-based control with zero setup and are OK with a subscription.
5. Vysor, best Chrome-based mirror
Vysor was the original Chrome-app screen mirror for Android and remains the smoothest one for anyone who lives in Chrome. It streams the screen at up to 60 fps over ADB, exposes a browser control surface, and requires no companion desktop app beyond the Chrome extension itself.
Where it falls short: Chrome or Chromium-only. Free tier limits resolution and has ads. Paid tier at $2.50/mo unlocks quality but the total spend adds up if you also pay for AirDroid.
Pricing:
- Free: 720p mirror with ads
- Paid: Pro at $2.50/mo for 1080p and no ads
Platforms: Android + Chrome/Chromium browser
Bottom line: Best pick if Chrome is already open all day and you want the fewest new apps.
6. AnLinkPhone, best LAN mirror in a browser tab
AnLinkPhone is a smaller, newer app that runs a WebRTC server on the phone. Open the URL it prints in any browser on the LAN and you get a live mirror plus input events without ADB, without cloud, and without paying. It is the closest to what someone building an “AI agent controls my phone” setup wants for the mirror piece.
Where it falls short: Newer project; occasional dropouts on busy Wi-Fi. Feature set is deliberately narrow (mirror plus input, nothing more). Documentation still catching up.
Pricing:
- Free: full app
- Paid: none
Platforms: Android + any browser on the LAN
Download: AnLinkPhone releases
Bottom line: Best pick for the LAN-only, no-cloud, no-ADB browser mirror.
7. Weylus, best tablet-as-input to a PC
Weylus flips the usual direction: instead of controlling the phone from the desktop, it turns an Android tablet or phone into a graphics tablet for the desktop. The desktop runs a Weylus server, the phone opens the URL in a browser, and stylus input goes to the desktop as pointer events. Handy for drawing, note-taking, and screen annotation.
Where it falls short: Not a two-way phone-control app; the direction is opposite of the others here. Requires the Weylus companion running on the desktop. Some stylus quirks on Samsung’s S-Pen.
Pricing:
- Free: full app
- Paid: none
Platforms: Android + Weylus server on Windows/macOS/Linux
Download: Weylus releases
Bottom line: Best pick when the goal is using the phone as a tablet for the desktop, not controlling the phone.
How to pick the right one
- If you want to script the phone from a browser: Termux plus a tiny HTTP server.
- If you want to see and click the phone screen from your desktop: scrcpy for the desktop terminal path, AirDroid or Vysor for the browser-first path.
- If you want file and clipboard sync but not full mirroring: KDE Connect.
- If you want no cloud, no ADB, no subscription: AnLinkPhone.
- If you want the phone to be a stylus for the desktop: Weylus.
- If you want to run an AI agent that drives the phone: Termux is the base, and the AI runs anywhere. XDA’s setup pairs it with a local LLM through a small script.
FAQ
What is the best free app to control an Android from a browser?
Termux for scripted control, AnLinkPhone for LAN mirroring, scrcpy if you can tolerate a one-time ADB setup. All three are open source and cost nothing.
Can I control my Android from a browser without root?
Yes with every app on this list. Termux, AirDroid, Vysor, AnLinkPhone, and KDE Connect run without root. scrcpy needs USB debugging enabled but not root.
Which app works over the internet, not just LAN?
AirDroid is the most polished internet-capable option. Termux plus a reverse proxy through Cloudflare Tunnel or Tailscale exposes the phone to the internet with minimal configuration. Others (AnLinkPhone, KDE Connect, scrcpy) are LAN-first by design.
Does controlling Android from a browser drain the battery?
Screen mirroring is the expensive part. AnLinkPhone and Vysor at 1080p drain around 8 to 12% of battery per hour of active mirroring. Termux running a small web server drains almost nothing when idle. AirDroid sits in between.
Can an AI agent use these apps to control my phone?
Yes. Termux plus a browser control loop is the setup the XDA piece described. Any HTTP-reachable interface (Termux, AnLinkPhone, or AirDroid’s local API) is what an AI agent scripts against, with the LLM running on a homelab or the same laptop.
