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.
“Pulumi's free tier is limited: The free Individual tier supports only 1 user, making it impractical for teams without paying.” DeepSeek V4 Flash · IaC · budget prompt · soft negative
“Team tier is paid (~$40–$150+/user/month); higher learning curve for ops teams not comfortable with programming.” GLM 4.7 FlashX · IaC · budget prompt · soft negative
“Pitfalls: Less mature ecosystem/modules than Terraform, "footguns" from general-purpose languages” Grok 4.1 Fast · IaC · negative prompt · soft negative
“it can be more complex and less budget-friendly operationally” GPT-5.4 mini · IaC · budget prompt · soft negative
Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 137 of the 189 answers that named Pulumi and are not a share of its labels.
452 of the 541 domain citations in answers naming Pulumi came from somebody else's page.
Pages are listed as the models cited 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 Pulumi'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 Pulumi, 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 pulumi.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.
