KubeArmor vs Kubeshark: at a glance
What is KubeArmor?
Every release in the feed is a candidate — the stable line is decided elsewhere.
KubeArmor's tracked feed contains only release candidates: three for 1.7.4 and one for 1.7.5, with no stable tag among them. The work divides into eBPF-level observability (DNS visibility moved from udp_sendmsg to udp_send_skb, DNS support and a verifier for kernel 6.17), platform compatibility (Ubuntu 26.04, openEuler 24.03 LTS-SP3, RHEL kernel iov handling), and supply-chain scoring — Renovate integration, workflow token permissions and provenance generation explicitly aimed at OpenSSF Scorecard numbers. Contribution is broad, with a dozen or more named authors per candidate.
What is Kubeshark?
Kubeshark rebuilt its backend for V2 and is redrawing the free tier around it.
Kubeshark is mid-transition from V1 to V2, announced for January 2026. The v52.11.0 release rewrote the backend entirely — V2 runs on the new implementation while V1 stays on the legacy one — and added cluster-wide L4 PCAP export plus L7-to-L4 mapping that ties API calls back to the TCP and UDP connections carrying them. Since then the releases have been smaller: connectivity map performance, per-flow PCAP files in snapshot archives, and a migration of every service domain from kubehq.com to kubeshark.com.

Every release in the feed is a candidate — the stable line is decided elsewhere.
◆ Current state
KubeArmor's tracked feed contains only release candidates: three for 1.7.4 and one for 1.7.5, with no stable tag among them. The work divides into eBPF-level observability (DNS visibility moved from udp_sendmsg to udp_send_skb, DNS support and a verifier for kernel 6.17), platform compatibility (Ubuntu 26.04, openEuler 24.03 LTS-SP3, RHEL kernel iov handling), and supply-chain scoring — Renovate integration, workflow token permissions and provenance generation explicitly aimed at OpenSSF Scorecard numbers. Contribution is broad, with a dozen or more named authors per candidate.
◆ Where it's heading
Kernel-version chase is the dominant constraint. An eBPF enforcement agent has to track kernel internals release by release, and a meaningful share of each candidate goes to keeping probes attached across new kernels and distributions rather than adding policy capability. The one genuine capability attempt in this window — TLD and subdomain enforcement — was merged and then reverted within the same release candidate, which suggests network-identity policy is being worked on and is not yet stable.
◆ Prediction
Expect TLD and subdomain enforcement to return once the regression behind the revert is resolved, and continued kernel and distribution matrix expansion. Whether 1.7.4 ever reached a stable tag is not visible in this feed.
Kubeshark
0.0INFRA · APIS
Kubeshark rebuilt its backend for V2 and is redrawing the free tier around it.
◆ Current state
Kubeshark is mid-transition from V1 to V2, announced for January 2026. The v52.11.0 release rewrote the backend entirely — V2 runs on the new implementation while V1 stays on the legacy one — and added cluster-wide L4 PCAP export plus L7-to-L4 mapping that ties API calls back to the TCP and UDP connections carrying them. Since then the releases have been smaller: connectivity map performance, per-flow PCAP files in snapshot archives, and a migration of every service domain from kubehq.com to kubeshark.com.
◆ Where it's heading
The product is moving down the stack. It started as an API-level traffic viewer and the recent work is all about L4 — connectivity maps, raw PCAP export, mapping L7 calls onto the connections beneath them — which puts it closer to a cluster-wide packet capture tool than a service-mesh observability dashboard. The licensing is moving in the opposite direction of the feature set: an almost-unlimited complimentary licence through the end of 2025 was replaced by one capped at 100 nodes, so the free tier is being defined rather than left open. Two releases also mention agentic infrastructure being staged but not yet usable.
◆ Prediction
Expect V2 to consolidate onto the new backend and the legacy V1 path to be dropped once the transition completes, since the release notes already describe V1 as being sunset. The staged agentic infrastructure is the most likely candidate for the next substantive feature, given it has been shipped inert twice.
