Quark Multiplayer partners with Xsolla to power a new era of virtual multiplayer

With a commitment to shaping the future of online infrastructure, MetaGravity is pushing the boundaries of what’s possible in multiplayer environments. In partnership with Xsolla, we are helping empower creators, developers, and players across platforms—ushering in the next era of the internet, from the cloud to the metaverse.

We’re bringing this to life through a strategic collaboration with Xsolla, integrating Quark Multiplayer, MetaGravity’s ultra-scalable network backend, with Xsolla’s Metasites platform. Together, we’re building the foundational infrastructure for the 3D internet—a vision that is rapidly becoming a reality thanks to our combined expertise.

Scalability without limits

One of the biggest challenges in creating multiplayer experiences within virtual environments is managing scale. Traditional infrastructure can struggle to handle thousands of concurrent players, leading to performance issues and poor user experiences.

Quark Multiplayer is designed to solve this, offering unprecedented scalability. Creators can now build large-scale, persistent worlds without worrying about the technical limitations that often accompany multiplayer development. This scalability is essential to the 3D internet, where vast, interconnected virtual environments will require infrastructure that can support hundreds of thousands—if not millions—of players in real time.

Through its integration with Xsolla Metasites, Quark makes this level of performance available to developers building the next generation of online experiences.

A shared vision for the 3D internet

This partnership marks the beginning of a long-term collaboration focused on enabling the 3D internet. Xsolla shares our vision of a decentralized, immersive, and persistent online future. Their Metasites platform, enhanced by Quark Multiplayer’s capabilities, is a step toward realizing this goal.

As part of this initiative, a Beta Program is set to launch soon, featuring core platform functionality. The evolution of the internet is shifting toward more open, persistent, and interconnected experiences—precisely the kind of environments Quark is built to support.

About the partnership

At the core of this collaboration is a proof-of-concept platform that combines Quark Multiplayer with Xsolla’s Metasites tools. This integration enables real-time, scalable multiplayer experiences and lays the groundwork for the next phase of interactive virtual environments:

• A customizable portal environment built in Unreal Engine, seamlessly integrated with Metasites experiences

• A versatile avatar system and public chat, offering players a rich, immersive social layer

• Support for up to 1 million concurrent users (CCUs) in a single-shard game instance, delivering true hyper-scale performance

Integration with Xsolla’s broader Metabrowser ecosystem—including Cloud Gaming, Login, Wallet, and Pay Station—adds robust identity and transaction management, making the platform more developer-friendly and secure.

For creators, this represents a breakthrough in multiplayer technology: a powerful, flexible foundation for building vast, engaging virtual experiences.

Looking ahead

MetaGravity and Xsolla will continue to expand this platform’s capabilities, focusing on decentralization, persistence, and interoperability—all crucial for building a truly global and interconnected metaverse.

Quark Multiplayer isn’t just solving today’s multiplayer challenges—it’s laying the foundation for the internet of tomorrow.
