Azure Resource Visualizer

This does one thing well: it turns Azure resource groups into Mermaid architecture diagrams. Point it at a resource group and it'll analyze every resource, map the relationships between them (network connections, data flows, managed identities), then generate a detailed diagram with proper layering and labels. The workflow is methodical: it lists your resource groups if you don't specify one, waits for confirmation, then digs through everything to understand how your App Services talk to your databases, how your VNets are structured, where your secrets live. The output is a markdown file with the diagram plus tables and explanations. Good for documentation or just understanding what you've actually built in Azure.
