We bring the world together through play

In 2004, Roblox was founded with a mission to power the imaginations of millions of people around the world. Together with industry-leading talent, we have embraced the hardest engineering and product challenges to bring people together through play. And we have only just begun. The Roblox platform rests on a rich technology stack that is as inspiring as our players and creators.

The Reality Engine

Our Reality Engine is the core of the Roblox virtual experience. It is a proprietary, high-performance, cross-platform, real-time simulation engine that dynamically scales fidelity to match device capabilities. The overall engine runs at 60 frames per second and can adaptively scale from an iPhone 4S to the latest gaming PC. 

Universal Game Client

The Roblox Reality Engine is packaged into our Universal Game Client, a single code base that can be built for all the platforms we serve, from iOS and Android, to Mac, PC, Xbox One, Oculus Rift, and HTC Vive. 

Real-Time Social Platform

Roblox is and always has been a social experience. At peak times, we process over 5 million requests per second across all backend services on the Roblox platform. Our vision is a single global community, playing together and communicating with each other in real-time, regardless of geographical and language boundaries.

Roblox Compute Cloud

The Roblox Distributed Compute Cloud is a collection of servers that host virtual experiences. At its peak, Roblox has hosted over 5.7 million concurrent users on our platform. Our matchmaking system finds the best game instance for each player, optimizing across friends in-game, geo‑location, server performance, and language, among other factors.

Team Development Infrastructure

We succeed when our developers succeed. We have a growing suite of tools to support an incredibly talented global community of over 7 million developers each month.
