I work with legacy socket systems and couldn't find a modern GUI tool that handled framing and charset encoding well.

What it does: - TCP/UDP with framing (length-prefix, delimiter, fixed-length) - 30+ charset encodings (UTF-8, EUC-KR, Shift-JIS, etc.) - Wireshark-style hex dump - Save test cases in collections - Built-in echo server

Built with Go + Wails. Runs on macOS/Windows/Linux.

Happy to hear feedback!
