## Overview

UFWUI is a Flask web interface and JSON API for managing a Linux host’s UFW firewall. The main workflow is a browser viewing firewall status and rules, then enabling/disabling the firewall or adding/deleting rules through the API; API handlers delegate those operations to helpers that invoke the host’s `ufw` command. The README also documents privileged, host-network deployment with `/etc/ufw` mounted. The HTML template was not sampled, so its detailed rendering behavior is not represented.

Main entry points: [`routes/api.py`](https://github.com/dev-mir2011/ufwui/blob/main/routes/api.py) (Firewall API), [`routes/frontend.py`](https://github.com/dev-mir2011/ufwui/blob/main/routes/frontend.py) (Page route), [`utils/helper.py`](https://github.com/dev-mir2011/ufwui/blob/main/utils/helper.py) (UFW command helpers), [`app.py`](https://github.com/dev-mir2011/ufwui/blob/main/app.py) (Flask app)
