VPC Atlas draws up-to-date AWS network diagrams in draw.io and Lucidchart

VPC Atlas is a new MIT-licensed Python 3.12+ tool that reads an AWS account using only Describe/Get/List/Search calls and renders network diagrams as .drawio and .lucid files. It outputs global, per-region and per-VPC pages, a JSON/Markdown/HTML inventory, and a dashboard with scan history and diffs between runs.

• Read-only by design: Describe*, Get*, List*, Search* calls with a minimal IAM policy
• Outputs .drawio and .lucid diagrams with AWS Architecture Icons plus JSON/Markdown/HTML inventory
• vpcatlas serve dashboard keeps scan history and highlights changes between runs
• Installed via pipx; requires Python 3.12+ and an AWS account with audit access
