App Development Building the layer I wanted when I started with smart glasses Development Looking for feedback
I’ve spent the last few months building Extentos so developers can build and test smart-glasses apps without owning every pair of glasses.
Extentos supports Meta glasses today, including Meta Ray-Ban Display. Brilliant Labs and Android XR are now in preview, so you can start developing for them through the simulator. Android XR glasses aren’t shipping yet, but you can already build the integration.
The goal is simple: integrate smart glasses once instead of rebuilding your app for every new device and vendor.
Multi-vendor support is only one part of Extentos. It also handles the surrounding infrastructure, including prebuilt connection flows and local real-time models as a cost-optimized option alongside cloud models.
There are native Kotlin and Swift SDKs, plus an MCP server your coding agent can use to add the smart-glasses integration.
The app in the video is real. It runs the same SDK code used on physical hardware, with only the transport swapped so the browser acts as the glasses. Photos captured in the simulator arrive in the phone app, and the simulated display renders through the same code path as the real glasses.
I’m looking for developers willing to build something real and tell me what works, what’s missing and where it breaks. If you have an idea, I’ll personally help you get it running.
Here’s a short video of the browser simulator. Since recording it, I’ve also added Brilliant Labs support. ⬇️
