Live across 12+ registries

Check the name before you start the repo.

Search domains, package registries, code hosts, and plugin marketplaces from one practical report. No hype. Just the collisions that matter.

Package registries and distribution first
Domains and brand surfaces first
Package and GitHub collisions first
Marketplaces and publisher names first
