A repository that tracks changes to Roblox's public fast flags.

Roblox FFlag Tracker

This repository is an offshoot of the Roblox Client Tracker, with the specific goal of tracking Roblox's application settings roughly in real-time.

Terminology

The F in FFlag stands for Fast, and Flag represents a boolean in Roblox's application settings.
Fast Flags are the most common type of setting, and in-general most people refer to Roblox's settings as FFlags.

In addition to Flags, there are other variable types supported.
Here is a list of every type:

Label Type
Flag bool
Int int
String string
Log byte

There are also behavioral classifications:

Prefix Label Description
F Fast A regular fast-variable that is initialized once
and does not change until a new session begins.
DF Dynamic Fast A fast-variable that can change at run-time, and
automatically updates every 5 minutes.
SF Synchronized Fast A fast-variable that is loaded by the server and
sent to the client.
