In what year was Roblox officially launched?

Roblox was officially launched in 2006.

The platform was formally released to the public on September 1, 2006. This date is different from the beginning of Roblox's development: David Baszucki and Erik Cassel started working on an early prototype in 2004, when it was known by names such as DynaBlocks. The website and early testing also predated the official public release.

Roblox's 2006 launch introduced the platform as a game-creation system built around user-generated content. Roblox Studio became available that same year, allowing players to make and publish their own experiences. A common mix-up is answering 2004, which refers to the company's creation and the platform's early development rather than its official release. The company later shifted increasingly toward community-made games, making creation—not just playing—a central part of Roblox's identity.
