Openness verdict. Build-time openness is real but multi-track. For the G2, Even ships a genuine public web/TypeScript SDK (Even Hub) — and first-party developer onboarding is now self-serve (signing in to the web hub flips the account to developer), though ship-time publishing still goes through an Even-run, manually-reviewed app store. Separately, a mature open-source third-party OS/SDK (MentraOS) officially supports BOTH G1 and G2 with no Even pilot gate and no Even store review, and an active raw-BLE community drives both models directly — so the ungated developer path is broader than the official channel alone implies. The older G1 has no first-party SDK or store, but it is reachable via MentraOS, an official BSD-licensed protocol demo, and mainstream tools like Gadgetbridge.

Overview

Even Realities is a Shenzhen/US eyewear startup making discreet, prescription-friendly HUD glasses — monochrome green heads-up displays in a normal-looking frame, deliberately no camera and no speaker (privacy positioning against Ray-Ban Meta). Two in-scope models: the G1 (2024; ~44 g; 640×200 green, reportedly ~20 Hz refresh, ~25° FOV, mic array, no camera) and the G2 (announced/shipped Nov 12 2025; ~36 g titanium/magnesium; dual micro-LED, ~576×288 px per eye per Even's developer docs — Even's own consumer spec sheet cites 640×350 — 60 Hz, up to 1,200 nits, ~27.5° FOV, four-mic array, no camera, no speaker). Both are peripheral displays paired to a phone over Bluetooth LE (5.4 on G2, up from 5.2 on the G1); on-board compute is display/firmware only (LVGL rendering), not standalone. The G1 retails $499, the G2 $599; the optional R1 control ring is $249 (out of scope as an accessory). Audio output routes through the phone, not the glasses.

Cheapest way to run your own code: The cheapest Even device is the Even G1 A at $499 USD in Brown1 or Green1 (non-prescription), but Even's own SDK, simulator and app store are G2-only, so a G1 developer must go through MentraOS, Even's BSD-2-Clause EvenDemoApp raw-BLE reference, or Gadgetbridge. The cheapest device on Even's own supported developer platform is the Even G2 at $599 USD, though hardware is not required to start — Even Hub ships a local simulator and developer access is free and self-serve.

What the listings leave out

Even G2

  • Two frame shapes at identical price and capability, three frame colours each and four lens options, for 24 purchasable variants in total, all currently listed as available.
  • The $599 headline is the frame-only, non-prescription price for the US, Canada and Hong Kong. It is the floor of a ladder that reaches $948 in the US for the same glasses with 1.74 lenses.
  • Prescription is a three-tier upcharge rather than a single option: Essential Slim (1.60) adds $159, Enhanced Slim (1.67) adds $229 and Superior Slim (1.74) adds $349 in the US, while the page shows only "From $159".
  • Progressive and UltraFit lenses cannot be bought online at all — "Progressive lenses and highly individualized UltraFit Lenses are exclusively available at our optician partners." Online sales are single-vision only.
  • Several markets are priced in US dollars rather than local currency: Australia, New Zealand and Singapore pay $649 USD, the UAE $699 USD and Saudi Arabia $749 USD, which is 8% to 25% above the US price for the identical product.
  • The EU, Switzerland and Norway pay €699 and the UK pays £599, which reads as parity with the US number because the figure matches, but is not.
  • Capability is region-split: the shipping policy states that Italy and Saudi Arabia "only support the sale of non-prescription eyeglasses", so the prescription SKUs are effectively unavailable there even though the storefront quotes prices for them.
  • There is no camera and no speaker on the device, so the SDK cannot capture what the wearer sees and cannot speak from the glasses. Anything audio-out is phone-side.
  • Choosing between G2 A and G2 B is a fit and shape decision only — identical price, capability and variant structure, with no developer consequence either way.
  • Accessories are priced separately and none are required for development: G2 Clip & Pouch $99, G2 Case $149, Temple Sleeves $5 for five pairs, Nose Pads $10 for ten pairs. The R1 ring at $249 is an input accessory and is explicitly optional in the Even Hub hardware quickstart.
  • Even Hub's app-submission guidelines say reviewers "run a beta build via Beta Testing", and there is no published requirement that a developer own the glasses or the ring to ship, nor a published review-turnaround SLA.
  • Even states the G2 is "eligible for reimbursement through FSA and HSA", a US-only payment nuance that is a reimbursement rather than a discount: "purchase your Even G2 upfront and submit your receipt."
  • Shipping is excluded from Northern Ireland, the Canary Islands, Faroe Islands, Greenland, the French overseas departments, Livigno, Cabbio and Campione d'Italia, and no P.O. Box or APO/FPO/DPO address is accepted — such orders "will be automatically canceled."
  • No stock-status string is rendered anywhere on the product pages. Availability is asserted only through JSON-LD schema.org/InStock and the storefront's availableForSale flag, both true on all 24 variants as of 2026-07-30.

Even G1 (G1 A)

  • One frame shape today, offered in two colours on the product page with a third still carried in the storefront catalogue at a higher price, and two lens options, for six catalogue variants.
  • The "From $499" headline is colour-dependent and the page does not say so: Grey1 is still catalogued at $599 non-prescription and $749 with single vision, while Brown1 and Green1 are $499 and $658. The colour picker offers only Brown1 and Green1, so $499 is real for what you can actually select, but the $599 Grey1 SKU has not been removed from the catalogue and no notice explains the split.
  • This is a reduction from the G1's original $599 with no vendor announcement. Even publishes no price-drop notice and sets no compare-at or strike-through price on any variant, so nothing labels $499 as either a permanent MSRP change or a promotion — treat it as the current price rather than a documented MSRP.
  • The second frame shape is gone without notice. The G1 shipped in two frame shapes, A and B; today /products/g1-b 301-redirects to /products/g1, which 301-redirects to /products/g1-a, and the store lists only "Even G1 A" while the G1 Clip & Pouch still sells a "Frame B" fitment whose "Frame B / Green" variant shows as unavailable. Even has published no end-of-life or discontinuation statement for the G1 B frame, or for the G1 at all.
  • The €529.95 EU price is the only non-round figure in Even's entire price list, every other model and market being a round number, which reads more like a markdown than a set list price — yet no promotional labelling accompanies it.
  • Only one prescription tier is offered, "Single vision" at +$159, against the G2's three index tiers. A strong prescription needing 1.67 or 1.74 lenses is a G2-only configuration online.
  • There is no first-party developer story: no Even Hub SDK support, no Even app store listing path, no simulator and no developer portal entry. Every route to running code on a G1 is third-party or community — MentraOS, the BSD-2-Clause EvenDemoApp protocol reference, or Gadgetbridge.
  • The R1 ring is incompatible — "Even R1 currently supports interaction only with Even G2" — so the $249 input accessory is not an option on the cheaper model.
  • G1 accessories are priced slightly differently from the G2's and are shape-specific: the G1 Clip & Pouch is $99 in the US and $100 in the base catalogue, sold in Frame A and Frame B fitments.
  • Even publishes no statement positioning the G1 as legacy, superseded or end-of-life. It retains a live product page, a footer nav entry and in-stock status across all markets, but it is absent from the current developer platform and the FSA/HSA eligibility copy names only the G2.
  • There is no camera and no speaker, the same as the G2 — a $499 entry price buys a display-and-microphone peripheral, not a capture device.
  • The regional caveats match the G2: USD pricing without local currency in Australia, New Zealand, Singapore, the UAE and Saudi Arabia, non-prescription-only sales in Italy and Saudi Arabia, and the same excluded-territory and P.O. Box / APO-FPO-DPO shipping exclusions.

Access

G2 has a real, official developer platform — Even Hub.

SDKA web/TypeScript kit published to npm (@evenrealities/even_hub_sdk) with a CLI (@evenrealities/evenhub-cli) and a local simulator (@evenrealities/evenhub-simulator)
LanguagesPlain HTML/CSS/JS or TypeScript, any stack (Vite/React) — there is no proprietary language or engine
Starter codeThe bundle is documented in the official everything-evenhub (MIT) repo with evenhub-templates (MIT, TypeScript) starter scaffolds
MaturityThe store and platform publicly launched April 3 2026. Docs currently say you can "Build plugins for the Even G2. Widgets, dashboards, and AI skills are next" — i.e. plugins are GA-ish, other surfaces are roadmap
Who can buildSelf-serve — you register an Even Realities account in the phone app and signing in at hub.evenrealities.com flips it to developer ("There is no toggle"), with no application, invite or allowlist step in the documented Quickstart. A separate Even Hub Pilot / Early-Access program opened applications in early 2026 for closer collaboration with Even's team (Android Authority)
CostNo developer fee is documented
LicenseSDK tooling and templates are MIT/BSD-2-Clause open source
Docshub.evenrealities.com/docs

Even Hub is not the only way in. Three further tracks reach these glasses, two of them with no Even gate at all.

TrackWhat it gives you
MentraOSMentraOS (by Mentra, the platform formerly known as AugmentOS) is a full open-source, cross-vendor smart-glasses OS whose TypeScript SDK moved off the cloud to phone-local miniapps in MentraOS 3.0 whose supported-glasses list officially includes both Even G1 and G2 (alongside Mentra Live, Vuzix Z100, and NIMO). You write one app that runs phone-side in the Mentra Runtime and drives display/mic over the glasses' BLE link — with no Even pilot gate and no Even store review
Raw BLE (G2)An active community bypasses Even Hub entirely — i-soxi/even-g2-protocol documents the G2 service UUIDs, 7-packet auth handshake, CRC-16/CCITT framing and protobuf payloads (with working teleprompter/calendar/notification demos), and MentraOS's own G2.kt is the widely-ported reference BLE implementation
G1No first-party SDK or program, but far from closed: Even ships an official EvenDemoApp (BSD-2-Clause) reference for the raw dual-BLE protocol (LC3 audio, 1-bit 576×136 BMP image packets), MentraOS supports G1, and the mainstream open-source Android companion app Gadgetbridge has explicit Even Realities (G1) support — so third parties reach the G1 despite the missing first-party SDK

App model

Phone-companion web model.

What an app isA G2 app ("plugin") is a web app whose code runs off-glasses — loaded in a WebView hosted by the Even Realities companion app on the paired phone (community docs describe the frontend loading in the iPhone Even App's WebView, with the app free to fetch from its own server backend)
What the glasses doThe glasses are a thin display+input client: the SDK sends layout/UI commands that the glasses render via LVGL v9 firmware, and relays mic audio, touchpad/ring input, IMU and device status back
TransportBluetooth LE
What you can callStandard browser APIs (fetch, Canvas) are available because the runtime is a WebView — but every outbound origin must be listed in the app.json network whitelist (full origins, no wildcards), and anything else is blocked before the request leaves the WebView
What does not existNo native on-glasses app runtime and no Unity/engine path; Even Hub's app model is web-only (the MentraOS and raw-BLE tracks in Access are not, though neither runs code on the glasses either)

This maps cleanly onto Extentos's phone-companion framing (phone mediates a peripheral display), with the key difference that Even's contract is a web/WebView + LVGL rendering pipeline rather than a native Android/iOS SDK, and Even ships no camera/speaker to drive. Sources: Even Hub overview, awesome-even-realities-g2, SDK feature notes (zenn).

Distribution

G2 ships through Even Hub, Even Realities' own on-device app store.

How users installOver-the-air from an "Apps"/Even Hub tab inside the Even Realities mobile companion app (also surfaced via a tab in the Even online shop); no cable or sideload needed for end users
How you publishYou package the app (.ehpk code package) with the evenhub CLI (evenhub pack app.json dist -o myapp.ehpk) and upload it through the Even Hub Developer Portal. For local testing you scan a QR code in the app's Developer Center to sync a build to the glasses
The two gates(1) Developer access is no longer one of them — onboarding is self-serve, since signing in to the web hub flips the account to developer; (2) apps reach the public store only via Even's review — though Private builds and email-invited Beta groups install unreviewed on real hardware — so Even is the gatekeeper/curator of public listing (the April 3 2026 launch shipped a curated set of ~50 apps)
Review policyEven does publish a detailed content-review policy: the App Submission & QA Guidelines mandate a manual review against a rejection-note checklist — package/manifest rules (reverse-domain ID, edition string, name ≤20 chars and must not contain "Even"), branding/screenshot-accuracy rules, functionality requirements (end-to-end on glasses+ring, 2-minute idle liveness, double-tap shutdown), and content restrictions (no medical diagnosis, financial advice, emergency-routing, or NSFW/hateful content)
Promotion flowA documented four-stage state machine — Draft → Test → Submitted → Released, with automated reviewer assignment, emailed decisions, and immutable Released versions (fix-forward only) — though a review-turnaround SLA is still not published
Without the storeBecause the G2 speaks an open BLE protocol, a developer can drive it directly from their own host/agent — gpsnmeajp/men-g2-ble-gateway is a Python gateway (its BLE layer ported from MentraOS's G2.kt) that bridges the glasses to HTTP, WebSocket, MCP and a local browser UI, i.e. a concrete self-hosted, no-store way to ship G2 functionality
G1Even runs no store or official distribution path — but a G1 owner reaches third-party apps through the Mentra app store via MentraOS, and anything outside that is a private/community app talking to the raw BLE protocol

Capabilities, limits & AI

CapabilityThird-party access
CameraNone on either device — Even ships no camera by design; a G2 plugin can request access to the phone's camera/album via SDK plugins with user permission, but there is no glasses-camera photo/video/frame API.
Microphone/audio captureYes — G2 exposes the four-mic array as PCM 16 kHz mono 16-bit streams, and AudioInputSource lets a plugin switch between the glasses mics and the phone mic at runtime (G1 streams LC3 over BLE).
Audio output/TTSThe glasses have no speaker; any voice output must route through the paired phone.
On-lens display/UIYes — monochrome green HUD; you render via SDK layout primitives (text containers up to ~1–2k chars, lists, images max 288×144 px, ~4 per page) compiled to LVGL on-glasses, with full-rebuild and flicker-free partial-update paths. Limits: no font-size API in the Even Hub SDK (the G1's raw BLE text protocol does carry a settable font size), no official animation API.
SensorsIMU/accelerometer at ten selectable pacing codes (ImuReportPace.P100P1000, which the docs note are "protocol pacing codes, not literal Hz values"); no dedicated on-glasses GPS — location comes from the phone bridge, and Private and Beta builds fire real permission prompts exactly as an end user sees them while QR sideload skips some during dev. Key-value string storage persists across reboot.
InputLeft/right temple touchpads (press/swipe/double-press) plus the optional R1 ring.
Reserved surfacesEven's own first-party apps are the reserved surfaces on both models — Even AI (reached by tap or the reserved "Hey, Even" wake phrase), real-time Translation (~35 languages), Teleprompter (AI/Manual/Automatic scroll modes), QuickList, Conversate, Navigation, and the Dashboard/notification HUD (Even Realities smart glasses); the SDK exposes no wake-word/gesture-system hook, so third-party plugins cannot hook the assistant/wake path.
AI & the assistantThe Even Hub plugin SDK exposes no assistant or wake-word API, so a plugin cannot hook the Even AI path — and "AI skills" is an announced-but-unshipped roadmap surface. The Even App itself ships an "Agent Configuration" setting (Settings → Even AI, visible only to enrolled Even Hub developers) that routes Even AI voice input to a developer-supplied OpenAI-compatible chat-completions endpoint and renders the reply on the HUD (Even's own tutorial, agent PoC) — a third-party assistant path Even documents in its support centre rather than in the developer docs. The practical path is bring-your-own-AI: because plugins are WebView apps with fetch, developers wire their own STT (Deepgram/Soniox/browser ASR) and LLM (Claude/OpenAI/Gemini) directly; there is no on-device AI. The BYO-AI framing is a direct consequence of that reserved assistant surface. Sources: SDK feature verification (zenn), Even Hub overview, Even Realities smart glasses, awesome-even-realities-g2.

Roadmap

  • Recent, dated: G2 hardware announced and on sale Nov 12 2025 (9to5Google); Even Hub Pilot Program applications opened in early 2026 (Android Authority); Even Hub store + developer platform publicly launched April 3 2026 with ~50 launch apps and a claimed network of 2,000+ independent developers (AndroidGuys).
  • Announced but unshipped: the docs explicitly flag widgets, dashboards, and AI skills as "next" (plugins are the only live first-party surface today).
  • Momentum: high and improving — a real npm-published SDK/CLI/simulator, active first-party templates and demos, a documented app-QA policy, and an established store, all within ~months, plus an independent open-source track (MentraOS) that already ships to both G1 and G2.
  • Gating that remains: ship-time store review, not developer entry — onboarding became self-serve, and the Draft → Test → Submitted → Released promotion pipeline is now fully documented, though a review-turnaround SLA is still not public. G1 is effectively legacy for Even's own tooling (no roadmap toward an official SDK), but stays developer-reachable through MentraOS, the BSD protocol demo, and Gadgetbridge.

In the landscape

Even Realities is one platform in the third-party smart-glasses landscape. See how open it is relative to other platforms, how AI works across them, and the full platform comparison.

Can you build third-party apps for smart glasses today? A platform-by-platform comparison — Meta, Snap Spectacles, Brilliant Labs, Rokid, RayNeo, Even Realities, Vuzix, Android XR, Apple and more: which have an official SDK, how apps are built and distributed, and whether you can publish publicly.

How open is smart-glasses development?

A mental model for the openness spectrum in smart-glasses development — SDK availability, license, build-time gating, and publishing gating — with today's platforms placed on it.

AI on smart glasses

How third-party AI works across smart-glasses platforms — which first-party assistants are reserved (Meta AI, Gemini, Ari), where you bring your own AI (phone-side, cloud, on-device), wake-word limits, and the voice-in → AI → voice-out surface that generalizes even where the assistant is closed.

How third-party smart-glasses apps are distributed

Smart glasses don't have one app store. The app-model taxonomy — companion mobile app vs. an app that runs on the glasses (native or web) — and why a single platform (Meta) offers two entirely separate developer systems: DAT and Ray-Ban Display Web Apps.
