What is Ably?
Ably promotes LiveObjects to stable, positioning real-time state sync as AI agent infrastructure
Ably has shipped LiveObjects to GA across Java and Cocoa platforms, completing a coordinated push that graduated experimental state-sync infrastructure into a production-ready capability. LiveObjects provides path-based distributed state with resilient subscriptions — pitched explicitly at AI agent coordination, live configuration, and multi-player experiences. In parallel, the AI Transport SDK added Temporal workflow support for durable agent patterns, and reliability work across .NET and JS SDKs tightened reconnection behavior from 120 seconds to 25 seconds and added WebSocket fallback for proxy-blocked networks.
What is SigNoz?
SigNoz extended observability into AI agent toolchains via an MCP plugin while steadily broadening alert routing and access controls.
SigNoz has been adding alert routing integrations at a steady clip—incident.io, Jira, and Jira Service Management—while tightening enterprise access controls with dashboard-level RBAC in custom roles. The most directional move was shipping as an Agent Skills MCP plugin, making SigNoz data queryable from AI coding environments like Claude Code and Cursor without switching to the SigNoz UI. A forced security migration off v1 alert history endpoints signals legacy debt being cleared.

Ably promotes LiveObjects to stable, positioning real-time state sync as AI agent infrastructure
◆ Current state
Ably has shipped LiveObjects to GA across Java and Cocoa platforms, completing a coordinated push that graduated experimental state-sync infrastructure into a production-ready capability. LiveObjects provides path-based distributed state with resilient subscriptions — pitched explicitly at AI agent coordination, live configuration, and multi-player experiences. In parallel, the AI Transport SDK added Temporal workflow support for durable agent patterns, and reliability work across .NET and JS SDKs tightened reconnection behavior from 120 seconds to 25 seconds and added WebSocket fallback for proxy-blocked networks.
◆ Where it's heading
Ably is converging on a two-layer platform: real-time pub/sub (the core business) and LiveObjects (distributed mutable state). Both are now being marketed as AI agent infrastructure, and the moves are coordinated — the Temporal plugin in the AI Transport SDK and the LiveObjects GA on multiple platforms are the same strategic bet that AI agents need durable real-time state coordination. Terraform provider maturity rounds out an infra-as-code story for teams running Ably at scale. The JS LiveObjects stable release is likely the next platform milestone.
◆ Prediction
A JavaScript LiveObjects stable release is the obvious next step given Java and Cocoa are already GA. The Temporal plugin pattern in the AI Transport SDK suggests additional agent framework integrations (LangGraph, CrewAI, or similar) are being evaluated, since the durable agent market is consolidating around framework-native patterns rather than DIY lifecycle management.
SigNoz
6.3INFRA · APIS
SigNoz extended observability into AI agent toolchains via an MCP plugin while steadily broadening alert routing and access controls.
◆ Current state
SigNoz has been adding alert routing integrations at a steady clip—incident.io, Jira, and Jira Service Management—while tightening enterprise access controls with dashboard-level RBAC in custom roles. The most directional move was shipping as an Agent Skills MCP plugin, making SigNoz data queryable from AI coding environments like Claude Code and Cursor without switching to the SigNoz UI. A forced security migration off v1 alert history endpoints signals legacy debt being cleared.
◆ Where it's heading
The product is pulling in two directions simultaneously: deeper enterprise controls (RBAC, PromQL conformance, access policies) and presence in agentic developer toolchains (MCP plugin, agent-friendly APIs). The MCP plugin move is the more architecturally significant—it repositions SigNoz from standalone observability dashboard to context-provider inside AI development loops.
◆ Prediction
Expect a richer MCP skill set that lets agents not just read SigNoz data but act on alerts—acknowledging incidents, modifying thresholds, or kicking off runbooks without leaving the coding environment.
