I Tried App Inspector...and You Won't Believe What Happened Next!
Blog post from LocalStack
App Inspector is an integrated feature within LocalStack that offers real-time visibility into every API call your application makes, capturing full payloads and IAM evaluation results before any interaction with a real AWS account. It simplifies debugging by providing a live, scrollable stream of operations, highlighting errors and warnings with visual indicators, and offering a dependency graph that maps AWS resources and operations. The tool eliminates the need for extensive logging by allowing users to view detailed operation information, including permissions and payloads, directly in the LocalStack web UI. This enhanced observability streamlines the debugging process and reduces reliance on traditional methods like adding console logs or sifting through CloudWatch logs.
