Overview

Kubeshark captures and indexes cluster-wide traffic at the kernel level with eBPF, parses L7 protocols such as HTTP, gRPC, Redis, Kafka and DNS, and decrypts TLS without key management. It offers a web dashboard, a workload dependency map, a CEL-based filter language (KFL) and PCAP export for Wireshark. An MCP server and Claude Code skills let AI agents query traffic for root cause analysis.

Who it is for: SREs and platform engineers debugging Kubernetes network traffic

Strengths

  • eBPF TLS/mTLS decryption without sidecars or key management
  • Retrospective PCAP export by time, node, workload and IP, with S3, Azure Blob or GCS storage
  • MCP server plus Network RCA and KFL skills installable as a Claude Code plugin
  • Parses HTTP, gRPC, GraphQL, Redis, Kafka and DNS with no code instrumentation

Weaknesses

  • Only useful on Kubernetes clusters; no standalone or non-Kubernetes mode is described
  • Kernel-level capture on every node; resource overhead is not documented in the README
  • Port-forward setup is not for production; an ingress controller is recommended
  • KFL is a custom query language that users must learn to filter effectively

What it needs

  • no GPU
  • Needs Kubernetes, Helm
  • Models: MCP-compatible assistants (Claude Code, Cursor, Copilot)
  • port 8899

Quick answers

Is kubeshark open source?
