## About Bloxstrap Technical Glossary

Definitions of every Roblox and Bloxstrap term: FastFlag, FFlag, DFInt, FLog, Hyperion (Byfron), ActivityWatcher, and ClientAppSettings.json. Understanding how Roblox bootstrapper flags, log watchers, and asset folders work under the hood on Windows.

Bloxstrap is a drop-in replacement only for the Roblox bootstrapper — it downloads, configures, and starts the official signed `RobloxPlayerBeta.exe` client without ever injecting DLLs or tampering with game memory.

## FAQ

### Where do I download Bloxstrap for Windows?

Get the Windows installer directly from [/download](https://bloxstraplabs.ink/download) on this host, then make sure the Microsoft .NET 6 Desktop Runtime x64 is installed.

### Is Bloxstrap safe to use with Roblox's 64-bit Hyperion anti-cheat?

Yes. Bloxstrap never modifies running process memory or injects DLLs; it only writes standard configuration files (`ClientAppSettings.json`) and launches the official Roblox binary.
