Movement

This is the first edition on this tier, so no move can be computed for Supabase yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Supabase is widely considered the best value for money” Qwen 3.7 Flash · Managed databases · budget prompt · first choice

“or Supabase if you want an integrated backend platform” Kimi K2 · Managed databases · budget prompt · first choice

“Supabase (or Neon if you want pure serverless Postgres with branching)” Kimi K2 · Managed databases · paraphrase prompt · alternative

“### PostgreSQL (specifically Heroku Postgres, Supabase, or RDS for PostgreSQL)” GLM 4.7 FlashX · Managed databases · paraphrase prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Why be cautious: If you only need a database, Supabase's full-stack platform (auth+DB+storage) can lead to overpaying.” Mistral Small · Managed databases · negative prompt · soft negative

“But for a mid-sized B2B company, I'd still usually choose a mainstream managed Postgres service first” GPT-5.4 mini · Managed databases · paraphrase prompt · soft negative

“usually better fits for smaller teams or product-led startups than a typical B2B ops environment” Perplexity Sonar · Managed databases · paraphrase prompt · soft negative

“good free tier, but be aware of its VC funding and the "free tier can change" risk” DeepSeek V4 Flash · Managed databases · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Supabase. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 45 of the 80 answers that named Supabase and are not a share of its labels.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Supabase's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Supabase, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at supabase.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
