## What it is
ffaker is a Ruby library for generating fake data such as names, emails, and addresses, originally created as a faster rewrite of the faker gem. It offers a largely compatible API with additional modules and localization data contributed by the community.

## Use cases
- generate fake names and emails for tests
- seed a database with realistic sample data
- speed up a slow Ruby spec suite
- create repeatable test data with a fixed random seed
- generate unique fake values in tests
- add fake data generation to a Rails development environment

## When to choose
- you need fake data generation in Ruby and want a lightweight, fast library
- you want API modules or locale data not available in faker
- you need deterministic fake data via random seeding in Minitest or RSpec

## When to avoid
- your project already uses faker and you don't need ffaker's divergent additions
- you need fake data in a language other than Ruby

## Facets
- artifact type: library
- maturity: stable
- function: data-generation, testing
- domain: developer-tools, testing
- platform: ruby, cross-platform
- tags: fake-data, seed-data, ruby-gem, test-fixtures, faker-fork
