Janus VR is a VR App for the Oculus Rift (Platform) and SteamVR. It is a platform that allows the user to see and experience the internet through virtual reality. Janus VR is an immersive, collaborative, multi-dimensional internet where web pages are represented as fully interactive rooms with doors acting as links between them. It allows users to have spatial walks through the internet.


The internet is seen as a collection of different search engines, apps and websites. Janus VR allows the user to experience the internet in 3D. The basic analogy to explain Janus VR is that webpages are rooms and the website links are doorways that connect the rooms. It can be defined as an immersive, collaborative and multi-dimensional internet. It is based on a VR version of Firefox called MozVR. The initial version of janus VR was named Firebox, but it was later decided to change the name since the browser is not in any way affiliated with Firefox web browser. The current iteration of janus VR supports Oculus Rift DK2 and Leap Motion. Rooms are created using an extended HTML and JavaScript and can be edited interactively from within the VR.

The growing community has more than 90,000 members who, in most cases, actively participate in the development of this multiverse.

Janus VR is inspired by Snow Crash, a novel by Neal Stephenson.


Janus VR - The World Within the Web

Janus VR is an immersive and collaborative internet browser. Named after the Roman God of passages, Janus VR re-imagines webpages as multi-dimensional spaces, linked by portals. Users experience 3D models, animations, spatial audio-video, and amazing data visualizations built as webpages, in an intuitive VR context. Any current webpage, hosted anywhere, can be viewed in Janus VR. Users enter Janus VR in a private homepage called the "pocketspace", that is their dashboard to the immersive web, with portals to popular or bookmarked webspaces, and other people online. Opening these portals allows users to embark on an endless journey, literally walking or flying through the internet, with others or on their own. In social mode, user avatars at the same webspace, can see, talk, chat and interact with each other. Users in party mode can even broadcast their movement in cyberspace. Our growing user-developer community has built thousands of diverse webspaces for users to explore with content ranging from art to architecture, education, games, and live entertainment. These experiences can be built and edited in Janus VR itself, using both spatially tracked game controllers and keyboard-and-mouse. Janus VR is a powerful combination of web content, VR and the collective imagination of our users.


Janus VR is an online network of multi-dimensional spaces, which are interconnected by portals. It allows the users to experience the internet in 3D by through the use of a VR HMDs. The salient features of Janus VR are:

  • Author content using existing 3D models
  • Navigation using traditional game controls or 3D hand gestures
  • Talk and chat in 3D
  • Surf 2D web in 3D

The environment in Janus VR is dynamically generated by using a portal-based system. The webpages with special HTML tags show enhanced 3D content and Janus VR allows interactive editing of these ‘FireBoxRooms’ directly. Site translators generate these FireBoxRooms after taking content, structure and data of existing sites and spatially generate content in a meaningful manner. The experience from Janus VR is multi-player or collaborative in which multiple people can navigate through virtual spaces together. The communication is done through sharing portals to new areas which each other or through voice or text. Recently, JavaScript (qtScript which is ECMAScript 3 complaint) enables the user to create a custom dynamic experience. The internet is then experienced in a purely visual and interactive manner through Janus VR.[1]

Recent enhancements to Janus VR include increased support for 3D object textures and greater flexibility in the sizing and positioning of doorways between the rooms, and the ability to record ghosts of your avatar to bring some life into otherwise static rooms. Support for video files has also been included and is already being used for virtual movie theaters and variety of other uses.

The current iteration of janus VR supports Oculus Rift DK2 and Leap Motion. janus VR is available for Windows, OSX, and Linux. It does not require installation and all that users have to do is to download the archive, extract it, and run the executable file.
