faker-ruby/faker
This system is a Ruby library designed to generate fake, randomized data for testing and development purposes. It provides a comprehensive suite of generators for diverse domains including blockchain addresses, book and movie titles, creature names, sports teams, and popular culture references. The library is structured with lazy-loaded namespaces to optimize performance and includes a command-line interface for direct usage.

Survey your own repository
faker-ruby/faker was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 2 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit cca4184947 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
