// THE PROBLEM

"Why is my subscriber not receiving data?"

Sound familiar? DDS debugging is notoriously difficult without the right tools.

πŸ”΄

QoS Misconfigs

Reliability mismatch = silent failures. Hours of debugging for a single policy error.

⚑

Latency Spikes

p99 > 10ms but where? No visibility into message timing across the network.

πŸŒ€

Topology Chaos

50+ topics, dozens of participants. Who talks to whom? It's a black box.

// FEATURES

Everything you need to debug DDS

From live capture to LLM-assisted diagnostics, HDDS Viewer gives you complete visibility into your DDS network.

πŸ”΄

Live Capture

HDDS Telemetry TCP + offline replay (.hddscap). Capture production traffic without instrumentation.
