It is not Unreal or Unity; the platform and its tooling (Roblox Studio) are built and maintained entirely in-house.1 game in this family → is not a single game but a user-generated-content platform: a client and engine on which millions of creators publish 'experiences' that others play.

Its anti-cheat, Hyperion (by Byfron, acquired 2022), runs in user mode on Roblox. The platform's audience skews very young, which puts child safety at the center of its trust story.1 game in this family → released it in 2006, and it runs on its own proprietary engine, scripted in Luau (Roblox's dialect of Lua), across Windows, macOS, iOS, Android, Xbox, and PlayStation. Its audience skews very young, with a large share of daily players under thirteen, which shapes how its safety and trust questions land.

Roblox installs no kernel driver; its protection lives inside RobloxPlayerBeta.exe. For families, the more useful levers are Roblox's own account-level parental settings (messaging limits, spending limits, age-based content), which matter more here than the anti-cheat does. The 64-bit client is required; the old 32-bit client was retired with HyperionAnti-cheatHyperion (Byfron)Hyperion is the anti-cheat built by Byfron Technologies, which Roblox acquired in 2022 and deployed with its 64-bit client in 2023. On Roblox it runs in user mode, compiled into the player client (packing, obfuscation, integrity and memory checks) rather than as a kernel driver, though Hyperion ships kernel components in some other games.1 game in this family →'s 2023 rollout.

Roblox's anti-cheat is Hyperion, built by Byfron Technologies, which Roblox acquired in 2022 and rolled out with the 64-bit client in May 2023. On Roblox specifically, Hyperion runs in user mode, not as a kernel driver: a Roblox engineer stated on the record in 2023 that it operates solely in user mode. It is anti-tamper code compiled into the player client itself rather than a separate process or driver, packing and obfuscating the client, checking code integrity, protecting process memory, and crashing the client when it detects tampering. So the trust ask is lighter than a kernel anti-cheat, though Byfron's Hyperion does ship kernel components in some other games. The Windows process is RobloxPlayerBeta.exe; there is no separate anti-cheat process.

Exploiting is a large, persistent problem, and Roblox runs periodic ban waves tied to Hyperion updates. The more consequential public record for Roblox is child safety: a 2024 Bloomberg Businessweek investigation, a short-seller report the same year, and a wave of US state and county lawsuits through 2025 and 2026 alleged the platform failed to protect minors. Roblox has responded with parental controls, messaging restrictions for younger users, age and content ratings, and time limits. For a platform with this young an audience, the trust questions are as much about safety as about cheating.
