| Ghost application only | Users who only need to know whether it is Ghost | Ghost traces, blog or content-platform behavior, DNS or CNAME patterns, and deployment clues | It cannot directly answer the hosting platform or brand | Low | Best as the application layer |
| Ghost hosting model | Users who need to judge self-hosted, managed-platform, and shared or cloud environments | Separate managed platforms such as Ghost(Pro), self-hosted Ghost, and other content-hosting environments | It needs more context and cannot be settled from application traces alone | Low-medium | Best as the main decision layer |
| Brand and provider final pass | Users who need the final platform and responsibility boundary | The Ghost stack does not automatically equal a managed platform, nor does it automatically settle provider boundaries | Public evidence may not always reach 100% certainty | Medium | Best as the final judgment layer |
