Registries to check

crates.io, NuGet, and Packagist are checked in your browser — the rest via this site's API.

How it works

  1. Your seed word becomes the first candidate.
  2. Wordnik adds synonyms and related words.
  3. Normalized candidates are checked against your selected registries; results fill in progressively.
  4. Optional: sign in with GitHub for AI-generated ideas.
