--- title: "Snap Spectacles" seoTitle: "Snap Spectacles for developers: SDK, app model & distribution (2026)" description: "Snap Spectacles for third-party developers — SDK access, app model, distribution, capabilities & AI, and where it sits in the 2026 smart-glasses landscape." type: reference platform: all vendor: snap related: - /docs/ecosystem - /docs/ecosystem/openness - /docs/ecosystem/ai - /docs/ecosystem/distribution - /docs/vendors/meta - /docs/concepts/capabilities --- > **Openness verdict.** Very open at both build and ship time. Snap ships a free public SDK (Lens Studio 5) plus a second, independent web path (WebXR Browser Lens, no Lens Studio), standalone on-glasses Lenses, and public Lens Explorer distribution open to any developer in the program. The publish gate is narrow: only Experimental APIs (and unsupported permission combinations) cannot ship to a wide audience — camera/mic/location combined with internet access IS publicly publishable via Snap's Transparent Permission system, including bring-your-own-AI Lenses through the Remote Service Gateway. The real access wall is hardware: the paid, US-only $99/month developer program (or, from fall 2026, a purchased pair of Specs). **Covered here:** Spectacles (5th generation, 2024) · Specs (2026). **Not covered here:** Spectacles v1 / v2 / Spectacles 3 (2016–2019) · Spectacles (4th gen, 2021). ## Overview Snap Inc.'s Spectacles are standalone, see-through binocular AR smart glasses running **Snap OS**, on which third-party **Lenses** (AR apps) execute directly on the device — no tethered phone required ([Snap Newsroom, SPS 2024](https://newsroom.snap.com/sps-2024-spectacles-snapos)). Two models are in scope. The **Spectacles 5th gen (2024)** is the current developer edition: Snapdragon AR2 Gen 1, four cameras driving the Spatial Engine and dual-hand tracking, binocular waveguide displays with a 46° stereo FOV at ~37 ppd, 13 ms motion-to-photon latency, 226 g, ~45 min battery ([developer-tech](https://www.developer-tech.com/news/snap-os-debuts-with-developer-friendly-spectacles-5-ar-glasses/)). **Specs (2026)** is the consumer/pro successor unveiled 16 June 2026 at AWE: fully standalone, two Snapdragon processors (one CV, one for Lenses), proprietary LCoS see-through display, 51° FOV, 16M colors, electrochromic lenses, 7 ms latency, TR90 frames at 132–136 g, up to ~4 h mixed-use battery plus a charging case; **$2,195** with a $200 refundable deposit, shipping **fall 2026** in the **US, UK, France** ([Snap Newsroom, Introducing Specs](https://newsroom.snap.com/introducing-specs-augmented-reality-glasses)). Both are camera+mic+speaker AR smart glasses with on-board compute (standalone, not a peripheral). ## Access The primary SDK is **Lens Studio 5** — a free, proprietary AR-first IDE from Snap supporting **TypeScript and JavaScript** natively, plus **SnapML** for running custom ML models on-device ([ar.snap.com/spectacles](https://ar.snap.com/spectacles)). It is GA and mature (10 Snap OS updates with 40+ new features/APIs over ~1.5 years, per [Snap Newsroom](https://newsroom.snap.com/introducing-specs-augmented-reality-glasses)). First-party frameworks — Spectacles Interaction Kit (SIK), UI Kit, Sync Kit, Auth Kit, Navigation Kit, Mobile Kit, and Commerce Kit (closed beta) — install from the Lens Studio Asset Library ([Introduction](https://developers.snap.com/spectacles/get-started/introduction)); sample projects are public on GitHub ([Snapchat/Spectacles-Sample](https://github.com/Snapchat/Spectacles-Sample)). Lens Studio itself is proprietary (free download); sample/community code is typically MIT. There is also a **second, Lens-Studio-free build path**: Spectacles ships a native browser with **WebXR**, so you can author AR with standard web tech (Snap recommends PlayCanvas) and run it in the on-device Browser Lens ([WebXR](https://developers.snap.com/spectacles/about-spectacles-features/webxr)). Agent-driven development is live, not just previewed: Lens Studio ships a built-in **MCP server** (AI Assistant → MCP → Configure/Start Server) that lets external coding agents — **Claude Code, OpenAI Codex, Cursor** — drive the IDE to generate, debug, optimize, and publish Lenses ([developer mode with Claude Code](https://developers.snap.com/lens-studio/features/lens-studio-ai/developer-mode/with-claude-code)). **Hardware access is gated by the paid Spectacles Developer Program: US-only, $99/month with a one-year commitment**, which ships the glasses and includes Snap support ([UploadVR](https://www.uploadvr.com/snap-spectacles-5-ar/)). Anyone can download Lens Studio and read the docs; you need the subscription (or, from fall 2026, a purchased pair of Specs) to run on real hardware. Docs: [developers.snap.com/spectacles](https://developers.snap.com/spectacles/get-started/introduction). ## App model Code runs **on the glasses**, not on a phone: a Lens is a Snap OS AR application authored in Lens Studio (TypeScript/JS + scene graph, optionally SnapML), deployed wirelessly to the device ([Introduction](https://developers.snap.com/spectacles/get-started/introduction)). Snap has broadened well past a single authoring path. A **Native Development Kit (NDK)**, announced at AWE 2026, brings **C and C++** code and libraries directly into Lenses (spatial mapping, physics, audio, networking, navigation), and a **Unity-to-Lens-Studio Migration Agent** translates Unity project structures, components, and scenes into native Lens Studio projects — Niantic Spatial ported its VPS via the NDK and Mapbox ported its Navigation Engine in under two hours ([Snap Newsroom, tools for Specs developers](https://newsroom.snap.com/snap-launches-new-tools-for-specs-developers)). Separately, **WebXR Browser Lenses are an entire second dev-and-distribution system**: standard web AR that runs in the on-device browser with no Lens Studio involved ([WebXR](https://developers.snap.com/spectacles/about-spectacles-features/webxr)). On-device networking is available (WebSocket API, and the Remote Service Gateway for cloud AI), and Snap now offers a first-party managed backend, **Snap Cloud** (powered by Supabase): managed Postgres with Row Level Security, Storage, server-side Edge Functions (TS/JS), and Realtime, with auth bridged from Snapchat identity via OpenID Connect — currently alpha/approval-gated and free during alpha ([Snap Cloud on Supabase](https://eng.snap.com/spectacles_supabase)). A companion **Spectacles phone app** exists only for auxiliary roles — phone-as-game-controller, Spectator Mode, screen mirroring — not for hosting app logic ([ar.snap.com blog](https://ar.snap.com/blog/lens-studio-cross-platform-ar-development)). **Fit with Extentos's phone-companion model: low.** Spectacles/Specs is a self-contained on-glasses AR runtime with its own managed backend and web path; there is no phone-side SDK surface where a companion app would drive the glasses the way Meta's DAT exposes the device. Extentos's abstraction targets a fundamentally different (phone-tethered) topology. ## Distribution Publishing is built into Lens Studio: hit **Publish**, supply an icon, a 3×4 preview image, description, and release notes; Snap's moderation team reviews the Lens within **2–3 business days** against community guidelines and, if approved, lists it in **Lens Explorer**, the on-device store ([Publishing Your Spectacles Lens](https://developers.snap.com/spectacles/get-started/start-building/publishing-lens)). Max Lens size is **25 MB** (vs 8 MB for mobile Snapchat). Public publishing is **open to any developer in the program** — no partner/enterprise gate — with review for a defined objective, 60 fps performance, no crashes, and design best practices ([submission guidelines](https://developers.snap.com/lens-studio/publishing/submitting/submission-guidelines)). Crucially, **Snap's Transparent Permission system lets published Lenses combine internet connectivity with sensitive user data (camera, microphone, or location)** as long as they use a supported permission combination (e.g. Internet Module + Camera Module, or Remote Service Gateway + Camera Module), gated at runtime by a per-launch permission prompt plus a hardware capture-LED indicator ([Transparent Permission](https://developers.snap.com/spectacles/permission-privacy/transparent-permission)). The **narrow residual block on wide-audience publishing is Experimental APIs** (and unsupported permission combinations / insecure http) — not camera-plus-internet in general. A separate distribution channel bypasses Lens Explorer entirely: **WebXR Browser Lenses are served from ordinary web hosting by URL with no app-store requirement or moderation review** ([WebXR](https://developers.snap.com/spectacles/about-spectacles-features/webxr)) — the Snap analog of Meta's Display Web Apps. Snap also runs **Spectacles Community Challenges** with cash prizes and reports 'hundreds of Lenses already published' for Specs. ## Capabilities, limits & AI **Camera:** the CameraModule provides on-device camera access to Lenses ([Camera Module](https://developers.snap.com/spectacles/about-spectacles-features/apis/camera-module)). Combining camera (or other sensitive data) with internet access is **publishable** via Transparent Permission with a supported permission combination, and Lenses using the dedicated Remote Service Gateway AI integrations can use camera access and ship publicly **without** Extended Permissions or Experimental APIs ([Transparent Permission](https://developers.snap.com/spectacles/permission-privacy/transparent-permission)); the only publish-blocking path is Experimental APIs. **Microphone/audio:** captured via MicrophoneRecorder; on-device speech via **VoiceML**. **Audio output/TTS:** speakers are available; TTS and generative voice come through the Remote Service Gateway (OpenAI TTS/Realtime, Gemini Live) with DynamicAudioOutput for PCM16 playback. **Display/UI:** full see-through binocular AR — you render a 3D Lens Studio scene (or a WebXR scene) into the wearer's FOV; SIK provides spatial UI. **Sensors:** Spatial Engine (SLAM), Depth Module, dual-hand tracking, plus GPS/location for outdoor location-based Lenses. **Input:** hand tracking with three SIK modes (ray-pointer, pinch, poke), voice, and optionally the phone-as-controller; no dedicated hardware controller or neural band. **Persistence/backend:** beyond on-device WebSocket, **Snap Cloud** (Supabase-backed) offers managed Postgres/RLS, Storage, Edge Functions, and Realtime with Snapchat-identity auth ([Snap Cloud](https://eng.snap.com/spectacles_supabase)). **AI & the assistant:** there is **no first-party Snap voice assistant exposed to third parties**; instead Snap offers a strong **bring-your-own-AI** path via the **Remote Service Gateway**, a Snap-brokered proxy to OpenAI (GPT chat, image gen/edit, TTS, Realtime voice), Google (Gemini text/multimodal, Imagen, Lyria), Snap-hosted **DeepSeek R1**, and **Snap3D** (text-to-3D GLB) ([Remote Service Gateway](https://developers.snap.com/spectacles/about-spectacles-features/apis/remoteservice-gateway)). On-device AI is available through SnapML custom models. Voice invocation of AI is a developer-built pattern (mic → LLM → TTS), not a reserved system assistant — and, per Transparent Permission, such camera+internet AI Lenses are publicly publishable. ## Roadmap **16 Jun 2026 (AWE):** Snap unveiled **Specs**, the 2026 consumer AR smart glasses, at **$2,195** + $200 deposit, shipping **fall 2026** (US/UK/France), alongside a **Snap3D** API, a shipping **Native Development Kit** (C/C++ + Unity Migration Agent), an **agentic development** path (Lens Studio's built-in MCP server driving Claude Code, Codex, Cursor), a Spatial Benchmark, and location-experience tools (**Fleet Management**, **Guided Mode**, **Guided Navigation**) ([Snap Newsroom](https://newsroom.snap.com/introducing-specs-augmented-reality-glasses); [tools for Specs developers](https://newsroom.snap.com/snap-launches-new-tools-for-specs-developers); [investor release, Sep 2025](https://investor.snap.com/news/news-details/2025/Snap-to-Launch-New-Lightweight-Immersive-Specs-in-2026/default.aspx)). Momentum is high: 10 Snap OS updates / 40+ APIs over ~18 months, hundreds of Lenses already published. **Announced-but-unshipped as of this writing:** Specs retail units (fall 2026), Commerce Kit (closed beta), and Snap Cloud (alpha, approval-gated). The 5th-gen Spectacles remain the shipping dev hardware via the $99/mo program until Specs ships. ## In the landscape Snap Spectacles is one platform in the third-party [smart-glasses landscape](/docs/ecosystem).
