Movement

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

By model

How each model treated AWS CDK across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

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.

“Developer experience / app teams write infra | Pulumi or AWS CDK” Kimi K2 · IaC · scale prompt · first choice

“AWS Cloud Development Kit is an open-source framework for defining AWS infrastructure in familiar programming languages” Claude Haiku 4.5 · IaC · comparative prompt · alternative

“The AWS CDK (which wraps CloudFormation) is a much better experience than raw CloudFormation.” DeepSeek V4 Flash · IaC · negative prompt · alternative

“Excellent if you are heavily locked into one cloud provider and want tight native integration.” Qwen 3.7 Flash · IaC · scale 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.

“CDK synthesizes to CloudFormation templates, making deployments 2-3x slower” Kimi K2 · IaC · negative prompt · soft negative

“emerging options (and note HashiCorp archived CDK for Terraform in Dec 2025)” DeepSeek V4 Flash · IaC · paraphrase prompt · soft negative

“CDK and Bicep make managing these external resources incredibly tedious” Gemini 3.5 Flash · IaC · direct prompt · soft negative

A head-to-head page exists where both products are in a category's top three. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named AWS CDK. 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 53 of the 78 answers that named AWS CDK 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 AWS CDK'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 AWS CDK, 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 aws.amazon.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.
