Limitations

• npm package names: npm normalizes package names (e.g., my-pkg and my_pkg are considered the same) and private packages are not visible, so even if the exact name appears available, publishing may still fail
• Domain checks: Uses DNS lookup which may show false positives for registered domains without DNS records
• Rate limiting: Some platforms may rate limit requests if checking many names
• Bot protection: Twitter/X, LinkedIn, and npm org checks use Playwright to bypass Cloudflare/bot protection
