script and tee are messy workarounds. v13 offers Session VCR:

Drag and drop a file into the GUI. Netcat GUI automatically chunks, sends, and verifies the transfer.

Troubleshooting a printer that uses raw port 9100? Use the UDP mode in v13. Send a wake-up sequence from the "Payload Library" (pre-saved hex strings) and watch for the printer's status response. No memorization required. You can even save common printer models as presets. netcat gui v13

Netcat GUI v13 is the definitive graphical interface for the legendary command-line utility, Netcat. For decades, Netcat has been the unsung hero of network debugging and penetration testing, but its power has always been locked behind a steep learning curve and cryptic terminal flags. Version 13 breaks down that barrier, offering a fully featured, multi-tabbed graphical interface that retains the raw power of the CLI while adding modern quality-of-life features.

The home screen is a dashboard. You can click New Listener, specify port 4444, and a new tab opens. In that tab, you see: script and tee are messy workarounds

No more terminal multiplexing. v13 allows ten listeners on ten tabs simultaneously, each with independent execution contexts.

One of the most praised additions is the "Payload Builder." Need to send a specific hex string or a Windows line ending (\r\n) instead of Unix (\n)? The v13 interface includes a hex editor and a raw text encoder. You can craft malformed packets, inject CRLF sequences for HTTP testing, or send binary files without worrying about terminal escape sequences corrupting the data. No more terminal multiplexing

Bandwidth monitoring is critical. At the bottom of every tab, a sparkline graph shows:

Additionally, a Flow Graph maps source IPs to destination ports visually using a D3.js canvas. This turns netcat into a basic IDS (Intrusion Detection System) visualization tool.
