Question 1

Is Exa or Sciverse better?

Accepted Answer

Exa scores 86.0 and Sciverse 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 wide enough to be decisive.

Question 2

Are Exa and Sciverse safe to install?

Accepted Answer

Exa: no known advisories. Sciverse: 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.
