Verbatim evidence the judge attached to positive labels.

“Compare a self-managed Backstage option, a managed Backstage option such as Roadie, and configurable commercial portals such as Port and Cortex.” GPT-6 Luna · Developer portals · scale prompt · first choice

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.
“Strongly Avoid ... Backstage is a framework, not a finished product. Many organizations treat it as such and end up disappointed.” GLM 4.7 FlashX · Developer portals · negative prompt · hard negative
“At 500 people, avoid self-hosting raw Backstage unless you have a dedicated, well-funded Developer Experience team.” Gemini 3.5 Flash · Developer portals · scale prompt · hard negative
“Why Not Backstage for Mid-Sized Companies? ... it's generally not ideal for mid-sized B2B companies” Kimi K2 · Developer portals · paraphrase prompt · hard negative

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 182 of the 197 answers that named Backstage and are not a share of its labels.
730 of the 730 domain citations in answers naming Backstage came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Every page backstage.io exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. Read September 29, 2026.
An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

What Backstage's own pages state, read October 5, 2026: backstage.io, backstage.io/docs/integrations. A claimed page can correct any of them.
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 Backstage'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 Backstage, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for Backstage by email, built from the raw record of the edition. It shows:
Backstage is among the products AI models recommend first in Internal developer portals this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
Badges read on light and dark pages. Alt text carries the claim, the category, the edition and the index, so it stays a citation where the image does not load.
