## What it is
Username Anarchy is a Ruby command-line tool that generates lists of likely usernames from people's first and last names for use in penetration testing. It supports plugin-based username formats, substitutions for partial names, and country-specific name databases to aid password brute forcing and username enumeration.

## Use cases
- generate username lists for password brute forcing
- enumerate likely corporate usernames from employee names
- expand LinkedIn-style first-initial last-name lists into full username candidates
- generate username format variants like first.last, flast, firstl
- build username wordlists from country-specific name databases
- avoid account lockouts by spreading guesses across many accounts

## When to choose
- you are doing authorized penetration testing or red team engagements
- you need username candidates for credential stuffing or brute force wordlists
- you only have partial names (e.g., first initial + last name) and need expansions
- you want a scriptable CLI that plugs into Kali Linux workflows

## When to avoid
- you need a GUI or interactive tool
- you are looking for password generation rather than username generation
- your use case is not authorized security testing - using this against systems without permission is illegal
- you need OSINT username harvesting from live sites rather than name-based generation
