Datafaker is a JVM library for generating fake data in Java, Kotlin, and Groovy, offering 250+ data providers covering names, addresses, dates, finance, and more. It is a modern, actively maintained fork of java-faker supporting locales, seeds, custom providers, and collections/streams of generated values.

Use cases

• generate fake test data for unit tests
• seed a database with realistic sample data
• anonymize production data for development
• create demo data for a showcase app
• generate random names and addresses in Java
• produce repeatable fake data with a fixed seed
• generate test passwords with symbol rules

When to choose

• you need fake data in Java, Kotlin, or Groovy on the JVM
• you want a maintained alternative to java-faker with many providers
• you need locale-specific fake data or reproducible seeded generation

When to avoid

• you work outside the JVM (use Faker.js, Python faker, or PHP faker instead)
• you need real, valid production data rather than synthetic data
• you require Java 8 support without using the unmaintained 1.x line
