Belatstrap gives you full control over Roblox Fast Flags — optimize performance, unlock hidden options, and manage configurations safely.
Apply performance, FPS boost, graphics, and stability presets with one click — no file edits, no restart needed.
Search and edit any of the 14K+ flags in the database, applied live in memory.
Injector verifies the Roblox process before writing — flags are changed directly in memory, never in game files.
Automatic HWID spoofer plus a manual MAC address spoofer to handle crashes and stale bans.
Detects your Roblox version, downloads the matching client automatically, in 12 languages.
One secure Discord login keeps you verified for 5 hours — no passwords stored, no repeated sign-ins.
Yeah. Uses memory injection to tweak FFLAGS in Roblox's process - just config flags, not touching game code or files.
We use memory injection with the safest methods available. Keeps detection risk low while still working properly. Can't guarantee 100% safety but we've built it to be as stealthy as possible.
Yep, completely free.
We use Discord's official OAuth to securely verify your Discord account and link it to Belatstrap. We never see or store your Discord password. We only receive the information you approve on Discord's authorization screen, and your session stays active for 5 hours so you don't have to sign in again. You can revoke access anytime through Discord → User Settings → Authorized Apps.

If your antivirus software is flagging this Tool fflag manager as a virus or malicious software, this is a false positive. The application is completely safe and contains no malware.
This tool works by modifying feature flags (fflags) in other processes — that's literally its entire purpose. To do this, it needs to write to the memory of running applications. Antivirus programs see this behavior and automatically flag it as "suspicious" because malware also writes to other processes.
The reality:
This is NOT a virus. It's flagged because of how it works, not because it's doing anything harmful.
