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 HAProxy Kubernetes Ingress Controller?
Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.
The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

Ably vs HAProxy Kubernetes Ingress Controller: editorial side-by-side
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.
HAProxy Kubernetes Ingress Controller
5.0INFRA · APIS
Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.
◆ Current state
The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.
◆ Where it's heading
This is a stabilisation series, not a feature series. The recurring theme is that ssl-passthrough interacts badly with everything layered on top of it — access control, backend reconciliation, rule generation — and each release fixes one more intersection. Test coverage is now landing alongside the fixes rather than after them, which suggests the maintainers are treating the passthrough path as a known weak spot rather than a series of unrelated bugs.
◆ Prediction
Expect 3.2.x to continue at a two-week cadence with further ssl-passthrough intersections, and expect any new capability to wait for a 3.3 line rather than arrive in a patch.
