## What it is
A visual web-based tool for inspecting and understanding ESLint flat configs. It runs via npx against a project's eslint.config.js, serving an interactive UI at localhost with live config updates, and can also build a static SPA snapshot of the config.

## Use cases
- visualize my eslint flat config
- debug why an eslint rule is applied to a file
- understand which rules come from which config block
- share a snapshot of my linting setup as a static page
- inspect eslint config changes live while editing
- onboard teammates to a complex eslint setup

## When to choose
- you use ESLint flat config (eslint.config.js) and want a visual breakdown of rules and config composition
- you need to debug rule resolution or config merging interactively
- you want a shareable static snapshot of your linting configuration

## When to avoid
- you use legacy .eslintrc configs instead of flat config
- you just want to run linting rather than inspect configuration
- you need a headless CI-only config validation without a UI
