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.

Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only ZenBrain Memory asks for
ZENBRAIN_CONTEXTSZENBRAIN_DB
Only XMemo asks for
XMEMO_KEY (secret)XMEMO_URL
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
