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.

Commands built only from what the marketplaces declare; the full set for every client is on each card.
Only the endpoint of Wipo Pearl responded at the last daily check. How we check endpoints
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.

Only Rube asks for
RUBE_API_KEY (secret)
Only Wipo Pearl asks for
PIPEWORX_API_KEY (secret)
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
