NagleCode, LLC

NagleCode, LLC is a niche software publisher focused on network diagnostics and packet-level communication tools, best known for its open-source utility Packet Sender. Designed for network engineers, developers, QA testers, and security auditors, Packet Sender provides a straightforward graphical interface for crafting, transmitting, and monitoring TCP, UDP, and SSL-encrypted TCP traffic across arbitrary ports. Typical use cases include verifying firewall rules, reproducing application-level bugs, stress-testing embedded devices, automating regression suites, and teaching socket-level protocols in classroom labs. The program logs every transaction with microsecond timestamps, exports packet sets as portable JSON files, and offers a command-line mode for scripted batch jobs or CI pipelines. Lightweight and portable builds for Windows, macOS, and popular Linux distributions make it easy to spin up ad-hoc client or server endpoints without permanent installation, while built-in SSL support allows quick validation of certificate chains and cipher negotiation. Because the entire project is hosted transparently on GitHub, the community can audit code, suggest features, and contribute protocol templates that expand the default library. Users who prefer a one-click setup can obtain Packet Sender free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always resolving to the newest release and enabling unattended batch installation alongside other networking utilities.
