Netcat Gui V1.3 Page

A developer writing a game server or chat daemon often needs to simulate multiple clients. The tabbed interface allows them to open three simultaneous connections to localhost:9999. They can type different commands in each tab and observe server behavior. Macros let them replay a login sequence across all tabs, simulating a load test.

The project roadmap teases features for version 1.4 and 2.0: netcat gui v1.3

Getting Netcat GUI v1.3 depends on your operating system: A developer writing a game server or chat

Upon first launch, v1.3 runs a diagnostic to locate nc, ncat, or socat. If none are found, it prompts you to install or point to a binary path. All configuration (history, presets, macros) is stored in ~/.netcat-gui/. Upon first launch, v1

| Risk | Severity | Mitigation in v1.3 | |------------------------------|--------------|------------------------------------------------| | Command injection via inputs | High | Input sanitization + argument array (no shell) | | Unencrypted data transmission| Medium | Warning banner when no TLS (Ncat --ssl option) | | Accidental listener exposure | Medium | One-click stop button + local bind only option | | Logging sensitive credentials| Low | Optional redaction filter (password patterns) |

Note: The tool inherits Netcat’s security posture – use over trusted networks only.
