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.

What is Retool?

Retool gives workflows their own run identity and sells self-hosted through Google Cloud.

Retool's first November week was about running and buying Retool in production. Workflows can now run as a chosen permission group, so scheduled and webhook-triggered runs no longer borrow a person's access. Self-hosted Enterprise can be deployed to GKE and billed through Google Cloud Marketplace, Microsoft SQL integration versions 1.0 and 2.0 were removed, and 4.88 reached the Edge channel. App testing entered public beta on November 3.

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.

Retool gives workflows their own run identity and sells self-hosted through Google Cloud.

◆ Current state

Retool's first November week was about running and buying Retool in production. Workflows can now run as a chosen permission group, so scheduled and webhook-triggered runs no longer borrow a person's access. Self-hosted Enterprise can be deployed to GKE and billed through Google Cloud Marketplace, Microsoft SQL integration versions 1.0 and 2.0 were removed, and 4.88 reached the Edge channel. App testing entered public beta on November 3.

◆ Where it's heading

After the late-October app builder GA, Retool is filling in governance and operations: testing for generated apps, AI spend controls, service identities for automation and procurement through a cloud marketplace. Older integration versions are being retired on a schedule.

◆ Prediction

Expect more admin and governance controls around workflows and the app builder, plus further marketplace or self-hosted deployment options.
