Vuzix

Openness verdict. Build-time: genuinely open — a free, publicly downloadable native SDK (Android + Apple) plus an MIT-licensed, now-GA third-party OS (MentraOS), no gatekeeping. Ship-time: fully open — a Z100 app is an ordinary phone app shipped through Google Play / the App Store, since the glasses are a display-only Bluetooth peripheral with no on-lens store or review gate. The MentraOS path strengthens this further: it is funded, open-sourced on GitHub, has a live app store, and is cross-vendor, so a Z100 integration written against it is portable to other makers' glasses.

Overview

Vuzix (Rochester, NY) is a long-time waveguide-optics and smart-glasses maker whose consumer/prosumer play is the Z100, a lightweight heads-up display in a normal-eyewear form factor. This page scopes to the Z100 (the "Ultralite" class); Vuzix's other products — the M400, M4000, Blade 2, Shield and the newer LX1 — are standalone Android head-mounted computers aimed at enterprise, with on-device compute and cameras, covered under a different SDK family (see below). Hardware snapshot (Z100): a single-eye (right) transparent 640×480 monochrome microLED waveguide display; no camera, no microphone, and no speaker (Vuzix positions this as a privacy/battery/weight advantage); tap-on-frame input; ~38 g; up to ~48 h battery; Bluetooth to an Android or iOS phone. It is a display-only peripheral, not a standalone computer — all logic and any AI run on the paired phone. Status: shipping — general availability 20 Nov 2024. Price: $499. Regions: sold direct and via resellers in North America and Europe; exact regional list not published.

Access

The official toolkit is the Vuzix Ultralite SDK, split by platform: ultralite-sdk-android (Java/Kotlin, added via JitPack as com.vuzix:ultralite-sdk-android, v1.9 / Mar 2025, requires Android 12+ and the Vuzix Connect app installed) and UltraliteSDK-releases-iOS (Swift, covering iOS, watchOS and macOS). Maturity: GA/stable — versioned releases, Javadoc, sample apps. Who can build: open — the SDK is public on GitHub/JitPack with no invite, dev-mode toggle, or partner gate; cost is free. License: not open source — use is governed by the proprietary "VUZIX SOFTWARE DEVELOPMENT KIT LICENSE AND CONFIDENTIALITY AGREEMENT". Docs live at support.vuzix.com plus the package Javadoc. Note — enterprise SDKs are separate: the Speech, Barcode and Connectivity SDKs target the Android M400/M4000/Blade/Shield/LX1 HMDs (they run on the glasses), not the Z100, and are out of scope for this page.

App model

Phone-companion, natively. With the Ultralite SDK your code runs on the phone/watch/Mac; the app pushes text, images and canvas draw-calls to the glasses over Bluetooth, brokered by the Vuzix Connect app (on Android, Connect owns the Bluetooth link; on iOS the SDK manages Bluetooth directly). The glasses are a thin remote display — no on-glasses runtime, no web/engine layer. Only one app controls the display at a time (requestControl() / isAvailable()), so an integration must arbitrate for control. A second, independent dev system exists: the Z100 is a first-class target of MentraOS (formerly AugmentOS, by Mentra) — an MIT-licensed, open-source OS whose SDK lets you build in TypeScript against a cloud/server-side runtime (AppServer.onSession(), session.layouts.showTextWall(...)), also phone-companion in shape. Crucially, MentraOS is explicitly cross-vendor — Mentra frames it as "Android for smart glasses," and the Z100 is only one supported device alongside Even Realities G1/G2, NIMO, and Mentra's own hardware (e.g. Mentra Live). A MentraOS app written against the Z100 therefore runs unchanged on other vendors' glasses — a materially different lock-in profile from the vendor-locked native Ultralite path. Fit with Extentos's phone-companion model: structurally excellent — the native Ultralite path is exactly a phone-app-drives-a-BT-display architecture. The caveats are that it is a different vendor and transport from Extentos's Meta/DAT target, and that the Z100 exposes only a display + tap (no camera/mic/audio), so the capture and audio primitives Extentos centers on have no hardware to bind to on this device.

Distribution

Because a Z100 app is just a phone app talking to a Bluetooth peripheral, distribution follows the ordinary mobile path: publish the Android or iOS app through Google Play / the App Store (or sideload/enterprise-distribute it) like any other app — there is no Vuzix-side app store, review gate, or release-channel invite for Z100 apps, and no on-glasses store. Public publishing is therefore fully open and gated only by the phone platform's own store review. Users install your phone app plus Vuzix Connect and pair the glasses. Alternate path: apps built on MentraOS distribute through the Mentra app store (launched May 2026) — installed from the user's phone — or directly from a plain web link; the store is also Mentra's stated monetization surface (developer subscriptions + app sales). (For contrast, the out-of-scope enterprise HMDs distribute Android APKs via the Vuzix App Store and MDM — that model does not apply to the Z100.) Preview→GA gating: n/a — the SDK is already GA and there is no staged-rollout program for the Z100.

Capabilities, limits & AI

Camera: none on the Z100 hardware, so no photo/video/frame API. Microphone / audio capture: none on the glasses — voice features (e.g., the Connect app's live translation/transcription) run on the phone's mic, not the wearable. Audio output / TTS: none — the Z100 has no speaker (this is inferred from Vuzix's consistent display-only positioning and the audio-on-phone design rather than an explicit spec denial). On-lens display/UI: yes, this is the whole device — a monochrome 640×480 waveguide you render to via UltraliteSDK with sendText(), sendImage(), setLayout() (Layout enum), a direct-draw Canvas, ScrollingTextView, Anchor/TextAlignment/TextWrapMode, LVGLImage, Icon, and UltraliteColor (Javadoc). Sensors/status: BatteryStatus and connection state via LiveData; tap-on-frame input is delivered through the EventListener interface. Motion (IMU) and location are not exposed to third parties in the documented SDK (see open questions). Input: frame tap only — no touchpad, controller, gesture camera, or neural band. Reserved surfaces: none in the Meta sense — there is no first-party on-device assistant or reserved wake word on the Z100 itself; the Vuzix Connect app's translation/transcription is a first-party phone feature, not a locked platform surface. AI & the assistant: there is no platform assistant on the glasses to open or restrict — the device is a dumb display. AI is therefore entirely bring-your-own on the phone side and fully open: point the display at any model/pipeline you like. MentraOS layers optional proactive AI, live captions and translation on top, again running off the phone/cloud. On-device (on-glasses) AI is not applicable — no compute or sensors on the Z100 to run it.

Roadmap

Shipped: Z100 GA 20 Nov 2024 ($499); Ultralite SDK reaching v1.9 (14 Mar 2025). 20 Feb 2025 — Vuzix and Mentra jointly announced AugmentOS/MentraOS with the Z100 as a launch device, adding an open-source, AI-centric dev platform on top of Vuzix's native SDK. That second dev system has since gone from announcement to a funded, GA platform: Mentra raised $8M (July 2025; backers include Android co-founder Rich Miner, YouTube co-founder Jawed Karim, and Toyota/Amazon venture arms), MentraOS shipped open-source on GitHub (April 2026), and the Mentra app store launched (May 2026), reportedly with a community of 4,000+ developers and dozens of shipped apps (live captions, translation, proactive AI) — the strongest openness signal on this page. Vuzix direction: the company is publicly steering toward an OEM waveguide + AI-glasses licensing strategy rather than a consumer-hardware treadmill — it has since shown the Ultralite Pro OEM waveguide reference platform and introduced the standalone-Android LX1 enterprise HMD (2026), neither of which is a Z100-class device or uses the Ultralite SDK. No Z100 consumer successor has been announced as of this writing. Publishing timeline: n/a — distribution is already open via standard phone app stores.
