Question 1

Is Accessibility Scanner or Scf better?

Accepted Answer

Scf scores 74.0 and Accessibility Scanner scores 70.0 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 Accessibility Scanner and Scf safe to install?

Accepted Answer

Accessibility Scanner: no known advisories, no build provenance. Scf: no known advisories. 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.

Upkeep	73	98	cadence, maintainers, status

Security audit	no known advisories, no build provenance	no known advisories	a summary — the full audit, free, is on each dossier
