Introduction

Fake is a Rust library and command-line tool for generating fake data in different languages, according to its README. Locales include English, French, Arabic, Traditional and Simplified Chinese, Japanese, Brazilian and European Portuguese, German, Italian, Welsh, Dutch and Persian.

The derive feature enables #[derive(Dummy)] to generate whole structs, with attributes to control fields. Feature flags add support for crates such as chrono, http, uuid, decimal types and others. Fakers cover names, addresses, internet, lorem, numbers, dates and more, and can be seeded with any RNG for reproducible tests.

Version 5.0.0 was released in March 2026.

In the quality loop it supports Rust unit and property-style tests.
