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 incident.io?
incident.io Investigations doubles speed: 68% of incidents get accurate RCA in under 5 minutes
incident.io's AI-powered Investigations feature — which auto-generates root cause hypotheses from the moment an incident is declared — just hit a significant performance milestone. Median time from incident open to an accurate channel message dropped from 6.7 to 3 minutes, and the share of incidents getting an accurate update within 5 minutes went from 8% to 68%. The supporting platform (bidirectional ticket sync, shardable alert rate limits, 24/7 schedule coverage) is being hardened around this flagship capability.

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.

incident.io Investigations doubles speed: 68% of incidents get accurate RCA in under 5 minutes
◆ Current state
incident.io's AI-powered Investigations feature — which auto-generates root cause hypotheses from the moment an incident is declared — just hit a significant performance milestone. Median time from incident open to an accurate channel message dropped from 6.7 to 3 minutes, and the share of incidents getting an accurate update within 5 minutes went from 8% to 68%. The supporting platform (bidirectional ticket sync, shardable alert rate limits, 24/7 schedule coverage) is being hardened around this flagship capability.
◆ Where it's heading
Investigations is the product's primary differentiation and it's receiving sustained investment. The Terraform provider overhaul (resource by resource), alert source improvements, and schedule coverage policy fill out the enterprise-scale platform. The bidirectional ticket sync closes a key workflow gap: incidents and external ticketing systems now stay in sync without manual updates, which reduces the coordination overhead during active incidents.
◆ Prediction
Investigations will likely expand to handle simultaneous incident streams and integrate directly with bidirectional ticket updates — turning the current 'hypothesis in channel' into an automated incident response loop that closes tickets as incidents resolve.
