ReconNinja v8.0.0 added a local desktop GUI — a dark-themed web app that runs entirely on your machine. Nothing leaves your host.

reconninja --gui

Opens automatically at http://127.0.0.1:7117

To use a different port:

reconninja --gui --gui-port 8080

The GUI is a Flask web application (gui/app.py) that:

1. Serves a single-page dark-themed UI at http://127.0.0.1:7117
2. Accepts scan config from the browser form
3. Runs the same orchestrator pipeline as the CLI
4. Streams real-time log output back to the browser via SSE
5. Displays findings in a live dashboard once the scan completes

All scan output is saved to disk exactly as it would be via CLI — same reports/ folder structure.

• Target — domain, IP, CIDR, or paste multiple targets
• Profile — Quick / Standard / Full / Custom
• Custom modules — individual checkboxes for every module
• Output formats — HTML / JSON / Markdown / SARIF / PDF
• Timeout — per-operation timeout in seconds

Everything you can do via CLI flags can be done through the GUI. The GUI does not expose every advanced flag (e.g. --masscan-rate) — for fine-grained control, use the CLI directly.

# CLI equivalent of a GUI "Full" scan
reconninja -t example.com --profile full_suite -y

GUI won't start:

pip install flask
reconninja --gui

Port already in use:

reconninja --gui --gui-port 8888

Browser doesn't open automatically:
Navigate to http://127.0.0.1:7117 manually.
