Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

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.
What each says it does
grab-cookie
Capture, store, wire, and verify a browser-session credential for sites that issue no API key and no OAuth: httpOnly session cookies, opaque localStorage bearer tokens, and custom auth headers. One DevTools Copy as cURL paste is the only human step; extraction, storage in the Windows Credential Manager or macOS Keychain, config regeneration, live verification, and expiry warning are automated. Complements connect-tool, which deliberately refuses cookie import. Markdown plus stdlib Python, no compiled binary and no MCP server.
