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.

Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for

MNEMOPAY_API_KEY (secret)MNEMOPAY_PERSIST_DIR
Only CRA AGENT asks for
CRA_KEY_FILECRA_NETWORKCRA_POLICYCRA_RPC_URLDATABASE_URL
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
