Hermes Link is a cross‑platform payload sender that lets you write arbitrary data to network sockets. Whether you're troubleshooting network services, testing servers, or simply need a quick way to transmit bytes to an address and port, Hermes Link gives you a clean, reliable interface backed by a flexible, fully functional codebase.
Built with Flutter, the app runs on Windows, macOS, Linux, Android and iOS with identical backend behavior. It supports both TCP and UDP transports, and can handle responses from the remote endpoint without crashing (many similar tools trip over sigpipe).
- Single codebase for desktop and mobile platforms
- Tested on Windows, macOS, Linux, Android, and iOS
- Connect to any address using:
- IPv4 or IPv6
- Fully‑qualified domain names (FQDNs)
