Which alternatives to Agent Skills Hub are open source?

6 of 9: Self Protocol, Usenami Signer MCP, PRXVT, MistTrack MCP, SIWA (Sign In With Agent), CryptoGuard. Openness is read from each project's own published license or repository.

Which alternatives run on the same chains as Agent Skills Hub?

1: Usenami Signer MCP. Chain support is self-declared by each project unless a named check says otherwise on its listing.

Has Sato Hub verified any of these?

Sato Hub reproduced the documented install for 3 of them: Self Protocol, PRXVT, MistTrack MCP. Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.

How is this list of alternatives built?

It is a rule over live records, not a hand-written list: every listing in Agent Skills Hub's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with Agent Skills Hub. It is rebuilt from the records, so it changes when they do.

Rule · Every listing in Agent Skills Hub’s own category (Security Tool) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with Agent Skills Hub.

This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.

“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.
