// THE PROBLEM
"Why is my subscriber not receiving data?"
Sound familiar? DDS debugging is notoriously difficult without the right tools.
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.
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.
Live Capture
HDDS Telemetry TCP + offline replay (.hddscap). Capture production traffic without instrumentation.
Topology Visualization
Force-directed graph + list view. Participants, topics, endpoints with real-time metrics.
Message Inspection
CDR2 decoding, hex/JSON views, 50+ commands via Ctrl+P palette. Drill into any message.
Timelines & Metrics
Latency p50/p95/p99, throughput graphs (5-min window), 20-bin histograms.
QoS Advisor
15 automated rules: reliability mismatch, deadline violations, liveliness timeouts, and more.
AI Diagnostics
ML-powered anomaly detection + LLM analysis via Ollama, Claude, or OpenAI.
8 Themes
Dark Pro, Cyberpunk, High Contrast (WCAG AAA), Catppuccin variants, Gruvbox.
5 Languages
English, French, German, Italian, Japanese. Auto-detects system language.
Single Binary
Linux, Windows, macOS. No runtime dependencies, no Docker, no Java.
