Question 1

Is Savvly or Z Zero better?

Accepted Answer

Savvly scores 74.0 and Z Zero scores 69.0 on the tashan score, which measures upkeep and freshness gated by real adoption. Neither number is a security audit and neither can be bought. The gap is narrow, so compare the evidence rather than the headline.

Question 2

Are Savvly and Z Zero safe to install?

Accepted Answer

Savvly: no known advisories, no build provenance. Z Zero: no known advisories, no build provenance. Every capability tashan measures is checked against the OSV advisory database at the version you would install today, for install-time scripts and for build provenance. The audit reads public evidence and never executes anything.

Question 3

How were these two compared?

Accepted Answer

Both were measured on the same day by the same scorer, from public signal only — npm download volume and publish cadence, repository activity, maintainer count and registry status. Nobody can pay to change a score, a rank or a listing.
