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 authentik?
authentik 2026.8.0 ships an Agent for machine identity and domain join, then enters rapid patch mode.
authentik is in a high-cadence maintenance cycle following the 2026.8.0 major release. Three point releases have landed in quick succession addressing admin file search, API autocomplete, and a blueprint field typo. The 2026.5 and 2026.2 legacy branches are still receiving backports, reflecting an enterprise install base that moves slowly between majors.

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.
authentik
5.0INFRA · APIS
authentik 2026.8.0 ships an Agent for machine identity and domain join, then enters rapid patch mode.
◆ Current state
authentik is in a high-cadence maintenance cycle following the 2026.8.0 major release. Three point releases have landed in quick succession addressing admin file search, API autocomplete, and a blueprint field typo. The 2026.5 and 2026.2 legacy branches are still receiving backports, reflecting an enterprise install base that moves slowly between majors.
◆ Where it's heading
2026.8.0 introduced the authentik Agent — enabling machine-initiated identity flows and device domain join — alongside an Actors entity type for non-human identity tracking. This is authentik's first explicit move beyond user-focused SSO into device and service account identity, putting it in territory occupied by commercial PAM and device trust vendors. The multi-branch backport pace signals that the team is supporting long deployment cycles while actively pushing the frontier forward.
◆ Prediction
The authentik Agent and Actors system are early features — expect expanded directory sync, credential lifecycle, and machine token management in the 2026.9 cycle. If domain join matures, authentik becomes a self-hosted alternative for organizations wanting to consolidate SSO and device identity on a single stack.
