2. Webaverse

Webaverse is an open-source, browser-based metaverse engine that allows developers to build and host virtual worlds and gaming experiences on top of it. Companies can host their metaverse projects wherever they want but they need to have Node.js 17 or later available.

The team behind the Webaverse aims to shift the power from big tech companies to users and creators, and set the foundation of an open metaverse that can be accessed through free and open tools. Therefore, their metaverse engine is fully open-source and customizable.

A noteworthy advantage of Webaverse is that the system is powered in users’ browsers, and therefore accessible across a variety of devices, including VR headsets.

To showcase the full potential of their metaverse engine, the Webaverse team has built The Upstreet — an AI-based and NFT-powered multiplayer online game. Upstreet supports user-generated content that can be dragged and dropped into the game.

Key benefits

• Allows developers to build and host virtual worlds on top of its engine
• Browser-based and accessible across a variety of devices
• Real-life projects already exist that show the Webaverse in action

6. Open Metaverse Interoperability Group (OMI Group)

The OMI Group is focused on building protocols for identity, social graphs, and inventory with the ultimate goal of bridging virtual worlds. As of 2022, the project is in its early stages of development, so there is no official scope of work yet. However, the OMI Group has outlined the key areas they are looking into, which include:

• Identity
• Avatars
• Inventory / Trading Virtual Items
• 3D content
• Friends Lists / Social Graphs
• Portable Scripted Objects / Scenes

The startup claims that they are not directly building the metaverse. However, they hope to form a consensus that will turn siloed virtual worlds into a network of interoperable ones.

Key benefits

• The OMI Group has multiple subgroups that work on and contribute to specific parts of the project, for example, the gLTF Extensions Group, OMI Github Backlog Refinement, the UX Research Group, etc.
• Aside from technical work, the project is focused on creating a community of artists, developers, and innovators to explore and design virtual worlds

7. Blender

Blender is a free and open-source tool for creating 3D content. It supports the entire 3D pipeline, including modeling, rigging, simulation, animation, rendering, motion tracking, and game creation.

Microsoft Mesh can be used to help you create virtual experiences, build connections, share spaces, and collaborate from anywhere. The platform can be integrated into various apps bringing Mesh-enabled mixed-reality experiences to your organization through digital avatars.

The two characteristics of Microsoft Mesh are avatars and holoportation. Avatars are digital representations of real individuals that are employed for virtual meetings while holoportation refers to speakers who address a meeting using their lifelike 3D models.

Key benefits

• Supports PCs, tabs, and other devices and does not require VR/XR eyewear to access the metaverse
• Allows you to choose from hundreds of combinations to customize your avatar (physical attributes, wardrobe, accessories, etc.)

Is it worth building a metaverse app?

Even though it is hard to predict when the metaverse will be fully implemented, many brands and consumers are already excited about its potential and have started taking the first steps towards turning this concept into real life.

For example, in one of their recent reports, McKinsey revealed that 59% of consumers are excited about transitioning their daily activities to the metaverse, while 57% of metaverse-aware companies claim they are early adopters. What’s more, 95% of business leaders expect that the metaverse will have a positive impact on their industry within 5-10 years.

According to Gartner, by 2026, 25% of people will spend an hour a day in the metaverse for activities such as work, education, shopping, and entertainment.

Beneath the hype, metaverse development continues, offering many interesting opportunities, including:

• New ways to engage with users, such as conferences in the virtual space, VR-based showrooms, virtual galleries, new marketing campaigns, and many more
• The possibility to rent or buy commercial spaces and build stores or showrooms for users to check out your products in the virtual world
• The opportunity to improve team collaboration by working together in metaverse workrooms
