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.

Tool names as the marketplaces declare them and as Ext Ops observed them on the endpoints (agent-exec as of 2026-10-13). More tools is not better in itself: compare what each needs for the job.
Settings each asks for
The marketplaces of agent-exec publish no settings it asks for, so we do not compare settings.
