Verbatim evidence the judge attached to positive labels.
“Choose Scout if your stack is primarily Ruby, Python, Node.js, PHP, or Elixir” Perplexity Sonar · Error monitoring · direct prompt · alternative
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.
“Scout is not suitable for Java, Go, or .NET stacks, or for frontend JavaScript error tracking or mobile crash reporting.” Llama 4 Maverick · Error monitoring · negative prompt · soft negative
“Don't use if your stack is Java/Go/.NET, or you need frontend/mobile crash reporting; it only fits certain stacks.” DeepSeek V4 Flash · Error monitoring · negative 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 7 of the 7 answers that named Scout and are not a share of its labels.
Twenty-six of the thirty-two domain citations in answers naming Scout 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 Scout'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 Scout, 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 scoutapm.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.
