TCP/IP Builder 1.9

TCP/IP Builder is a lightweight network testing and debugging tool by DRK Software / Leandro H. Fernández. It lets you quickly open TCP or UDP connections, send custom data, and observe responses in real time. Designed for developers, QA engineers, and network administrators, it can act as either a client or a simple server, making it useful for prototyping protocols, simulating devices, verifying firewall and port-forwarding rules, or troubleshooting socket connectivity issues.

The interface focuses on clarity and control: you can compose payloads, transmit them on demand or at intervals, and view incoming data in text or hexadecimal form. Connection parameters are easy to adjust, and logs help you capture exchanges for later analysis. If you need a straightforward way to test network services without writing code, TCP/IP Builder provides a practical, no-frills environment to craft requests, inspect replies, and validate behavior over TCP or UDP.
