About FastFlags.xyz

FastFlags.xyz is an independent, unofficial reference for Roblox Fast Flags — built and run by localrcc. It is not affiliated with, endorsed by, or connected to Roblox Corporation in any way.

Why this exists

Every Fast Flag search online turns up the same handful of thin lists (a hundred or so flags, no sourcing) or raw engine dumps with zero context. FastFlags.xyz tracks 28,109 flags in one searchable database, is upfront when something is genuinely undocumented rather than guessing, and links every claim on this site back to a real flag page rather than asserting it and moving on.

What we do and don't claim

Roblox doesn't publish official documentation for Fast Flags, so nothing on this site is official. We don't fabricate descriptions, ratings, or reviews — see the full methodology for exactly how each flag is sourced and labeled.

Corrections

Found a flag with a wrong description, a stale device tag, or a broken tool link? Message localrcc on Discord — corrections get applied directly to the underlying data, not just this page.
