| Brand-word or page-trace shortcut | Users who only want a rough first glance | Footers, brand words, DNS traces, and template fingerprints | This most easily merges the platform brand, frontage layer, and raw provider into one answer | Low | Use only as a first-pass screen |
| Vercel Hosting platform attribution | Users who need to judge whether the website or frontend project looks more like Vercel Hosting | frontend deployment traces, framework fingerprints, DNS or CNAME patterns, preview environments, and edge-network behavior | It answers the platform direction, but it still cannot replace raw-network and seller-boundary judgment | Low-medium | Best as the main decision layer |
| Platform model plus raw-layer cross-check | Users who need to separate the platform model from final responsibility | Separate frontend platform entry, edge layers, and whether the real backend or API still runs elsewhere; The raw provider does not automatically equal Vercel, and Vercel does not automatically cover the entire application stack | It needs more context and often ends in high confidence rather than absolute proof | Medium | Best as the final judgment path |
