K3Shark
See your cluster's network
Kubernetes network debugging with visual topology mapping. See how pods communicate, trace packet flows, and diagnose network policies without wrestling with kubectl and YAML. Works with any K8s cluster - cloud or local.
Why K3Shark?
Visual Network Topology
See your cluster's network as an interactive graph. Nodes, services, and their connections displayed visually instead of buried in YAML files and log output.
Offline Capable
Load pcap files and cluster snapshots for offline analysis. Debug production issues without needing live cluster access. Perfect for post-mortems and security analysis.
Built for Debugging
Not another monitoring dashboard. K3Shark is designed for debugging - packet capture, flow tracing, and network policy testing. Find the problem, don't just watch metrics.
Features
Topology Visualization
Interactive graph of pods, services, and network flows. Zoom, filter, and explore.
Packet Capture
Capture and analyze traffic between pods. Filter by namespace, service, or protocol.
Network Policy Testing
Test network policies before applying. See what traffic would be blocked or allowed.
Flow Tracing
Follow a request through your cluster. See every hop from ingress to backend.
Integrated Terminal
Shell into pods, run kubectl commands, all from one interface.
Offline Analysis
Export cluster snapshots and pcap files for later analysis without cluster access.
