Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

MODELFLARE_API_KEY (secret)MODELFLARE_BASE_URLMODELFLARE_OUTPUT_DIR
Only Runway ML asks for
RUNWAYML_API_SECRET (secret)RUNWAY_ALLOWED_ROOTRUNWAY_DOWNLOAD_ROOTRUNWAY_REQUEST_TIMEOUT_MSRUNWAY_UPLOAD_TIMEOUT_MS
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
