How to choose between them

Agent Swarm ranks #1 on the installs + stars + recency blend; Agent Phone has the most raw installs (25,408 last month) if adoption is all you weigh. 7 of these 15 offer a remote endpoint (no local process to run); the rest are local stdio servers. 5 document no required env vars - paste the config and go; the others need env vars set first (each page lists exactly which). Where we've compared two of these head-to-head, the comparison is linked on each one's page.

How this list is ranked

Ranked from live registry + GitHub data: monthly installs (npm/PyPI), GitHub stars, and commit recency - recomputed nightly. No pay-to-rank, ever. The 15 above lead the full list of 104, all of which you can see on this page. The other 633 we track have stopped being maintained, or nobody is using them yet. Full recipe: how we verify.
