Registries

29 registries: a default set of 10 popular ones, plus 19 additional.

Default (popular): npm, PyPI, crates.io, RubyGems, NuGet, Hex, pub.dev, Homebrew, Docker Hub, CocoaPods

Additional: Homebrew Cask, Hackage, opam, CPAN, LuaRocks, Nimble, DUB, CRAN, Julia General, conda-forge, vcpkg, Snapcraft, deno.land/x, Shards, VPM, CTAN, Pursuit, WordPress Themes, Chocolatey

Registries with scoped/namespaced packages (Maven Central, Go modules, Packagist, Helm, JSR, etc.) are excluded. Names there aren't globally reserved, so "available" isn't meaningful.

Run staked --list-registries to see everything with IDs, ecosystems, and supported languages.
