Features

TCP Server & Client

Start a TCP server or connect as a client. Handles concurrent connections with smart auto-reconnect and real-time message logging.

UDP Broadcast & Listen

Broadcast UDP messages to any IP and port, or listen on any interface. Ideal for IoT and automation protocol testing.

<1ms Echo Response

RFC 862 Echo Protocol support. TCP server echo latency under 1ms for real-time round-trip testing and performance verification.

String Format Options

Switch between None, Hex, ASCII, and UTF-8 formatting on the fly. Inspect raw bytes or human-readable text without restarting.

Multi-project Profiles

Save and reload connection profiles. Switch between projects instantly without re-entering IP addresses and port settings.

Traffic Load & Intervals

Configure sending intervals and packet counts for stress testing. Verify server stability under sustained load conditions.

Use Cases

IoT & Industrial Automation

Verify communication between automation devices and PLCs. Test proprietary protocols before deploying to production hardware.

Server Stress Testing

Send sustained traffic with configurable intervals and packet counts. Identify stability issues before they reach production.

Education & Network Learning

Visualize TCP handshakes and UDP datagrams in real time. A practical companion for network programming courses.
