What is Ably?
Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.
Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.
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.

Ably
7.5INFRA · APIS
Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.
◆ Current state
Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.
◆ Where it's heading
The direction is Ably as AI agent infrastructure. LiveObjects' own documentation positions it explicitly for 'AI agents, live configurations, and collaborative experiences.' The AI Transport SDK is a purpose-built layer for agentic workflows — durable sessions, multi-turn conversations, tool execution — layered on Ably's realtime primitives. This is a deliberate expansion from realtime messaging platform into the transport layer that agents run on.
◆ Prediction
The AI Transport SDK will add more model provider codecs — the OpenAI Responses integration suggests Anthropic or Gemini support is next. LiveObjects needs to reach stable across remaining SDKs (Python, .NET) before the feature can be adopted uniformly.
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.
