Xcode & Android Studio ready

Sync your emulator to the
Extentos Simulator.

The Extentos Simulator is a pair of smart glasses in a browser tab.

Build and tune your whole app against it. When you tell your agent to mint a simulation, your emulator automatically gets wired to the simulator and the Simulator opens in your browser. If your agent can’t open a browser, it prints out the URL for you to click.

  • No hardware needed

    Your device's webcam, mic, and speaker stand in for the glasses' camera, microphone, and audio. Plug nothing in to start.

    How it's wired

  • Seconds per loop

    Save a file and refresh — no device to grab, no APK to push, no Xcode launch between tries. The build loop is hot.

    Try it live

  • iOS and Android at once

    Point your iOS and Android emulators at the same Simulator session and exercise both platforms side by side, in one place.

    Read the SDK docs

  • Every vendor in one Simulator

    Ray-Ban Gen 2, Display, Oakley Meta — and more vendors on the roadmap — all simulated from the same browser tab. Switch glasses, keep the loop.

    Cross-vendor architecture

  • You or your agent drives it

    Click through it yourself in the browser, or let Claude Code, Codex, or Cursor drive it over MCP and verify each step.

Test end to end.

A real Android app driven entirely from the browser. A coding agent adds a feature mid-video, then verifies its own work against the live simulation.

Hey gold.

Hey there, what would you like me to capture right now? An image, a description of what you see, or a video? — Yes, can you capture an image, describe what you see, and then save it in the app? — Got it, I'll take a look and save a photo at the same time. One moment. Saved. I see a wide snowy mountain scene with a smooth… — Okay, anyway, can you end this conversation?

Hi there, what would you like to capture right now? A photo, a video, or a live view? — Yes, can you pull up the display? — Home is up on the display with photos and videos, you can pinch one to open it.

Okay, very nice. Can you end this conversation?

And then we can actually ask our coding agent for a new feature we want to add, or something.

Can you add a note section in the mobile app, and also add it to the display?

And what it will do now is add it, of course, and then it will actually use its agent verification tools to drive the simulation itself. So if we just let it work, it will show itself using it in a minute.

So right here we can see the agent is actually using the agent verification tools to verify it's working. You can see it in the event log.

So here we can see what our coding agent has added, and we can test this on the new vendor, Android XR. Just close it here.

Hey gold.

Hey there, what would you like me to capture? A photo, a video? — Yes, can you pull some notes up on the display? — All set, your notes are up on the display.

Alright, very nice. Can you go back to the home page on the display? — Home is up on the display: notes, photos and videos, pinch one to open. — And what device are you on right now? — You're using Android XR display glasses, they've got a camera, microphone… — Okay, anyway, remove the display and end this conversation. — Okay, closing things up.

Install the MCP. Tell your agent to mint a simulation.

Drop the Extentos MCP server into Claude Code, Cursor, or Windsurf — and minting a Simulator is one prompt away.
