Meta published a developer blog on October 14 that puts a SHARPER focus on Immersive Web SDK 1.0: AI AGENTS can now RUN and PROFILE web-based VR apps on a Meta Quest headset plugged into a developer’s computer, not only inside a desktop emulator. The framework remains a website-first WebXR stack built on Three.js, and Meta says frame-rate and browser MEASUREMENTS in that LOOP come from the DEVICE itself.
The Meta Horizon OS Developers post frames 1.0 as a STABLE foundation—grabbing, locomotion, Havok physics in a Web Worker, spatial UI, and mixed reality—plus an AI-native tool suite. Every new PROJECT ships with a Model Context Protocol server and agent SKILLS so an agent can INSPECT a scene, move simulated inputs, PAUSE the engine, and SEARCH the real IWSDK API instead of guessing.
Until now that TEST loop stayed on the desktop emulator. With 1.0, Meta says the SAME commands can drive an app on a CONNECTED Quest. In Meta’s own DEMO, an agent PLAYED every level of Hyperform on Quest 3, FIXED slowdowns, and REPLAYED until the game HELD 90 FPS. That result is a COMPANY demonstration, not an independently verified benchmark, a caveat Superpower Daily also notes.
Agentic Scene Composer and Glasses Preview
The Agentic Scene Composer lets developers and AGENTS edit the SAME 3D scene: people arrange assets visually while the agent WRITES models, materials, and BEHAVIORS in code. Meta says it used the workflow to BUILD Connect Island, an open sample with a pavilion, session stage, and day-night cycle.
Version 1.0 is also POSITIONED for Meta VR Glasses, which Meta still TARGETS for Spring 2027. Gaze acts as a POINTER—LOOK at a target, then PINCH to select—and Meta says existing ray-based buttons, menus, and grabbable objects can use that INPUT without separate gaze-specific code. On Quest 3 and 3S today, head direction stands in for eye tracking and a CROPPED view PREVIEWS the glasses’ narrower field of view; REAL eye tracking waits for the HARDWARE.
What Changed in the Release Notes
The v1.0 release notes list the technical HOOK for connected testing as --native-xr-control, which connects IWSDK XR and ECS automation to a browser-owned immersive session on Quest. They also document gaze-and-pinch through world.xr.features.gazeTracking, with DIRECT touch and ACTIVE grabs taking PRIORITY over gaze, and hand or controller rays returning if tracked gaze becomes unavailable.
Developers start with npm create @iwsdk@latest. Meta notes that teams already on 0.5 should UPDATE IWSDK packages TOGETHER and check the changelog for a few changed defaults. The Meta VR Start Developer competition, which Meta says runs through November 18, 2026 with $1M in TOTAL prizes, is open to immersive web experiences as well as native titles.
