Question 1

Is Postgres or Supabase better?

Accepted Answer

Supabase scores 99.0 and Postgres scores 74.0 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 Postgres and Supabase safe to install?

Accepted Answer

Postgres: no known advisories, runs an install script, no build provenance. Supabase: 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.

	Postgres	Supabase	what it means
tashan score	74	99	upkeep + freshness, gated by adoption
Adoption evidence	2k/wk	193k/wk	the raw public signal the score came from
Last release	active	active	npm publish or repo push
Upkeep	87	99	cadence, maintainers, status
Expertise grade	solid	not graded	an LLM read of its own documentation against a fixed rubric
Security audit	no known advisories, runs an install script, no build provenance	no known advisories	existence of findings is always free; the detail a licence buys is on each dossier
Licence	AGPL-3.0	Apache-2.0
Maintainers	more than one	more than one	bus-factor risk
