RP1 and Metaverse Standards Forum Launch Sneeze, First Open Spatial Browser Engine

RP1 and the Metaverse Standards Forum unveiled Sneeze on June 15, 2026 — the first open-source metaverse browser engine built for spatial computing, released under Apache 2.0.

What Happened

The announcement arrives as the industry confronts a structural gap: the browser engines that power today's web — Blink, WebKit, Gecko — were built for flat, document-oriented content and cannot natively handle the real-time, proximity-aware, volumetric experiences that spatial computing demands. Sneeze closes that gap.

Functioning as the spatial equivalent of a web page rendering engine, Sneeze maintains a live scene graph, manages network connections, executes service logic, and renders a shared spatial scene in real time. The engine delivers the 90 frames per second that XR hardware requires, compared with the 30 fps ceiling that characterizes current web pages.

RP1 serves as lead architect and maintainer of the project. Co-Founder and Chief Architect Dean Abramson described the core problem: "The web was not designed for proximity-based content, for real-time 3D services. Sneeze was built to close that gap."

Technical Architecture

Multi-origin scene composition is managed through a Scene Object Model (SOM), which governs how content from different operators is layered into a single coherent spatial environment. Discovery is proximity-based: as a user moves through physical or virtual space, Sneeze loads spatial services present in that location automatically, without explicit navigation. Asset formats include glTF for 3D geometry, KTX for textures, and SPIR-V for shaders, all Khronos standards. Identity and geospatial anchoring draw on W3C Decentralized Identifiers and OGC GeoPose, respectively.

Standards Governance and Academic Dimension

The engine is governed under the Metaverse Standards Forum, a body hosted by the Khronos Group that brings together organizations including Apple, Meta, Microsoft, NVIDIA, and Qualcomm. Neil Trevett, President of the Khronos Group and Chair of the Metaverse Standards Forum, noted that building the spatial web requires a constellation of standards from dozens of organizations — a coordination challenge OMBI is designed to address.

The University of Rochester's Center for Extended Reality simultaneously launched the Open Metaverse Academic Alliance (OMAA), positioning universities and research institutions as contributors to ongoing standards development and training pipelines for the emerging field.

Strategic Context

RP1 is constructing what it describes as the world's first native metaverse browser powered by Sneeze and plans to disclose additional details at AWE 2026, where Co-Founder and CEO Sean Mann and Neil Trevett are presenting on June 16 in a fireside session, followed by an OMBI architecture and roadmap roundtable on June 17. Mann has framed the project in explicitly anti-proprietary terms: "Any organization can start building spatial infrastructure on an open standard that cannot be discontinued."

The approach mirrors the historical dynamic of web browser engines — no single company controls Blink or WebKit's specifications outright — and aims to prevent the spatial internet from developing under the governance model of current app stores or closed platform ecosystems.

Outlook

Sneeze positions the Metaverse Standards Forum as the standards body of record for the next generation of internet infrastructure, at a moment when spatial computing hardware from multiple major manufacturers is reaching commercial scale. The Apache 2.0 release removes licensing friction for enterprise adoption and hardware integration, while the OMAA partnership signals a push toward long-term institutional legitimacy. RP1's native browser, once released, will serve as the reference implementation — a proof of concept that the open spatial browser engine model is viable at production quality.
