## What the models said for it

- "the best choice is usually Amazon Cognito if you want the lowest-cost, AWS-native customer identity platform" (Perplexity Sonar, CIAM)
- "Amazon Cognito (Best overall free tier for AWS users or general startups)" (Grok 4.1 Fast, CIAM)

- "caution if you want a more polished developer experience or need broader CIAM features without AWS-specific tradeoffs" (Perplexity Sonar, CIAM)
- "though they often require more custom work. I'm not recommending them as the first pick here" (GPT-5.4 mini, CIAM)
