Quay vs Kubeshark
A side-by-side editorial comparison of Quay and Kubeshark — release velocity, themes, recent moves, and the top alternatives to consider.
Quay vs Kubeshark: at a glance
What is Quay?
The public release feed is pure CVE backporting across two frozen branches.
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
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.

Quay
5.0INFRA · APIS
The public release feed is pure CVE backporting across two frozen branches.
◆ Current state
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
◆ Where it's heading
This is what a supported enterprise registry looks like from the outside: two older branches on life support for customers who have not moved, with feature development happening somewhere the feed does not see. The pattern is machine-driven — cherry-pick robots, changelog bump bots, Renovate-style dependency updates — with human authorship visible mainly on the security fixes. Nothing here indicates what the current development branch is doing.
◆ Prediction
Expect the 3.10 and 3.12 branches to keep receiving paired dependency CVE backports on the same cadence until their support windows close. Any read on Quay's product direction needs a source other than 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.
