README

Nibble is a CLI tool for local network scanning that focuses on speed and ease of use.

Select a network interface, and Nibble scans your local subnet. Lists hosts, hardware manufacturer, open ports and their services.

• Lightning fast scans using lightweight threads
• Stealthy, emits no network signals before a scan is started
• Colors uses your terminal theme colors
• Skips loopback and irrelevant adapters
• Defaults to SSH, Telnet, HTTP, HTTPS, SMB, RDP, and more
• Can be set to a list of custom ports that are stored for future use
• Target mode for targeted network scans
• Reads service banners on open ports (for example, OpenSSH or nginx versions)
• Looks up hardware vendors:
  • Raspberry Pi, Ubiquiti, Apple and 40,000 other vendor ids
• Headless mode with JSON output for scripting and automation
