Where each is published
| Marketplace |  JSONPad documentation | |
|---|---|---|
| Official MCP Registry | Listed Version: 1.0.0 No figure published Not marked · First seen |
Listed Version: 0.1.0 Downloads/month (npm): 186 Downloads/week (npm): 14 Not marked · First seen |
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.
