Original title: Open WebXR versus Commercial Game Engines: A Socio-Technical Position Analysis for an Open, Sustainable, and Interoperable Metaverse
Luca Turchet, Michel Buffa · September 2026
People imagine the Metaverse as an open, connected network of virtual and augmented spaces. Today, however, creators usually build extended reality (XR) apps using commercial game engines and sell them in closed app stores. This locks experiences to specific platforms. The researchers compared open WebXR standards against these commercial engines across hardware, software, developer tools, governance, ethics, and sustainability. WebXR works by running XR directly through web browsers, bypassing proprietary stores. The team found that WebXR offers an accessible, device-independent path for education, research, cultural heritage, prototyping, and public-interest projects. Meanwhile, native engines excel at heavy graphics, low lag, and large products. Instead of choosing one winner, creators should pick based on needs: WebXR for openness, or game engines for sheer performance.
Imagine you want to read a book. You could go to a public library, which has many books anyone can borrow, or buy a personal copy that you own and can read anytime. The library is free and open, but you might have to wait or travel; your personal copy is always there and customized to you, but it costs money and only works on your shelf. In this paper, the public library represents WebXR—open, accessible, and sustainable for communities—while the personal book represents commercial game engines—powerful and tailored, but tied to specific devices and platforms.
For anyone building or using virtual worlds, the choice of tools affects who can participate and how long those worlds last. This paper shows that open web standards can make the Metaverse more inclusive, while commercial engines keep it polished and fast.
