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.

No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of vulcan publish no list of tools, so we do not compare tools.
Settings each asks for
Only QuantConnect asks for
AGENT_NAMEQUANTCONNECT_API_TOKENQUANTCONNECT_USER_ID
Only vulcan asks for
VULCAN_WALLET_NAMEVULCAN_WALLET_PASSWORD (secret)
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
