Your Meta Wearables Device Access Toolkit Development Partner
Build for Meta glasses with an early partner on the Wearables Device Access Toolkit
The Meta Wearables Device Access Toolkit is Meta’s SDK for building apps that run on the whole Meta glasses family: Ray-Ban Meta Display, Ray-Ban Meta, Oakley Meta, and Meta AI glasses. It gives developers access to the camera, microphone, speakers and AI assistant on the device, and on Ray-Ban Meta Display it also drives display UI components: text, images, lists, buttons and video playback.
L+R was an early partner on Meta’s Wearables Device Access Toolkit, before general availability, and was named alongside Disney, Logitech and Microsoft as first partners for Meta’s AI Glasses SDK.
We use it to build native glasses apps, extend existing mobile products onto the glasses, and design hands-free experiences around voice and first-person vision.
Product teams, platform teams and brands hire us when they want to ship on Meta glasses and need engineers who have already worked inside the toolkit. Glasses are one part of our wider wearable technology practice.
Meta opened the glasses to developers. We were there for it.
What We Build with the Wearables Device Access Toolkit
- Custom Meta Glasses App Development. Native apps built against the toolkit, end to end, across the supported glasses family.
- Extending Existing Apps to Meta Smart Glasses. Bring your current product to the glasses without rebuilding it.
- Wearable Experience Design. UX designed specifically for hands-free, voice, and first-person contexts.
- Toolkit Feasibility & Technical Consultation. What the SDK can and cannot do for your use case, before you commit a roadmap.
- Flutter Integration. Ship on the glasses from a Flutter codebase, without writing the native bridge twice.
- Real-Time Content Development for Wearables. Live, responsive content that works in the moment.
What You Can Build with the Meta Wearables Device Access Toolkit
Meta’s smart glasses put a camera, microphone, speaker, and AI assistant on your customer’s face, and Ray-Ban Meta Display adds a small heads-up display in the lens. The Wearables Device Access Toolkit is what lets your app reach them, across Ray-Ban Meta Display, Ray-Ban Meta, Oakley Meta, and Meta AI glasses.
We turn that into products people actually use.
Here’s where it gets interesting:
- Voice and vision, not screens. Users ask a question, look at something, and get an answer or action back in real time. No tapping, no looking down.
- Built for your use case. Customer-facing experiences or internal tools for your team. We design the app around what your business actually needs, not a generic template.
- Connected to your existing app. Glasses and phone work as one product. What a user starts on mobile continues on the glasses, and what they capture on the glasses flows back to your app.
L+R turned our public art into a walking tour people actually wanted to follow. Hands-free and immersive, it got visitors to look up from their phones and into the work.”

Questions Teams Ask About The Meta Wearables Device Access Toolkit
The toolkit, in plain terms.
It is Meta’s SDK for building apps that run on Meta’s glasses. It gives developers access to the camera, microphone, speakers and AI assistant on the device, and on Ray-Ban Meta Display it also drives display UI components: text, images, lists, buttons and video playback. L+R was an early partner on Meta’s Wearables Device Access Toolkit, before general availability, and was named alongside Disney, Logitech and Microsoft as first partners for Meta’s AI Glasses SDK.
The whole family: Ray-Ban Meta Display, Ray-Ban Meta, Oakley Meta, and Meta AI glasses. Display support arrived in May 2026 and brought the heads-up display into scope alongside the camera and audio surface the camera glasses share. L+R builds for all of them.
Yes. The toolkit is what lets your app reach the camera, microphone, speakers and AI assistant on the glasses, and the display on Ray-Ban Meta Display. We build native glasses apps with it, extend existing mobile products onto the glasses, and design hands-free experiences around voice and first-person vision.
On Ray-Ban Meta Display, yes. It supports standalone web apps built in standard HTML, CSS and JavaScript, driven by the Neural Band, so a web team can build for the glasses with the languages it already uses. And for a Flutter product, our open-source plugin flutter_meta_wearables_dat bridges the toolkit directly.
The field is small because the toolkit is new. L+R was an early partner on Meta’s Wearables Device Access Toolkit, before general availability, and builds on it for product teams today, with engineers who have shipped inside it rather than read about it, and who have published tooling for it in the open.
They put a camera, microphone, speaker and AI assistant on the wearer’s face, working hands-free and in the moment. On Ray-Ban Meta, Oakley Meta and Meta AI glasses there is no screen to tap, so apps are built around voice, vision and capture. Ray-Ban Meta Display adds a small heads-up display in the lens, so an app can also put something in front of the wearer’s eye.
That is the right question to settle before you commit a roadmap. We run toolkit feasibility and technical consultation as its own piece of work: what the SDK can and cannot do for a specific use case, answered by the engineers who have built inside it. Tell us what you want to ship and we will tell you where the toolkit stands today.
Yes. Load any URL into displayglasses.dev and see how it reads on the glasses before any device code is written, no hardware and no sign-up required.
Yes. Glasses are one part of our wearable technology practice, which covers connected devices, companion apps and the experience design around them.
L+R's Ray-Ban Display Simulator
We built displayglasses.dev so developers can see how a web app reads on Ray-Ban Meta Display without owning a pair. It reproduces the additive waveguide blend over real-world background scenes, which is what determines whether your interface is legible in a bright street or a dim room.
Load any URL into the simulated heads-up display, adjust its position, size and brightness, swap the background scene, capture or record the result, and preview it on a phone or on the glasses themselves via a QR code. It is free to use.
It exists because we needed it. That is also the shortest answer to whether we have worked inside this platform.
Our Open-Source Toolkit Plugin for Flutter
Reaching the glasses from a Flutter app means bridging to Meta’s native toolkit on iOS and Android first. Every team building this way has to do that work before it can build anything interesting, so we did it once and published it.
flutter_meta_wearables_dat is an MIT-licensed Flutter plugin, live on pub.dev, that wraps the Meta Wearables Device Access Toolkit for both platforms. It handles device registration, camera permissions, live video streaming, and raw frame access, which is the foundation any camera or vision feature on the glasses is built on.
It is free, the source is public, and it is the code we build with. If your team is evaluating whether a Flutter product can reach Meta glasses, that question can be answered by reading it.
