Self-hosters repeatedly burn hours trying to get the standard media stack (qBittorrent/Gluetun + Prowlarr + Sonarr/Radarr/Lidarr + Jellyfin/Plex) actually talking to each other. Installing the containers is the easy part; the soul-crushing part is the interconnection — consistent volume/path mapping for hardlinks, download categories, indexer wiring, and remote-path mapping. People want an appliance that does the wiring for them and validates it end-to-end, aimed at intermediate users who are not Docker experts.
The differentiator is a configuration validator/wizard, not another installer. The hard, valuable part is encoding the tribal knowledge — shared hardlink-friendly volume layout, download-client categories, Prowlarr→arr sync, remote path maps — and then actively testing the full grab→import→rename→library chain and surfacing the exact broken link. Ship the diagnostics ('your /downloads path differs between qBit and Sonarr') and you've built what every 'please share a working compose' thread is really begging for.

One-click install of *arr apps is a solved problem; what is not solved is automatically wiring them together correctly and proving the chain works. Existing tools either assume sysadmin skill (Saltbox) or stop at installation (CasaOS/DockSTARTer), leaving path mapping and indexer/category wiring as the recurring failure point that frustrates non-expert self-hosters.
