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 Currents?
Currents is building the agent-native CI layer: machine-readable failure context, IDE integration, scoped API tokens.
Currents is a Playwright/Cypress test observability platform that has made two explicitly agent-targeted moves in recent months: a shareable .md endpoint for test failures (structured failure context fetchable by AI agents without a Currents login) and a VS Code/Cursor extension that puts CI run history inside the IDE where AI agents can act on it. Personal Access Tokens — scoped per-user API tokens replacing the shared org key — just landed this week, addressing a real security gap in the API access model.

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.
Currents
6.3INFRA · APIS
Currents is building the agent-native CI layer: machine-readable failure context, IDE integration, scoped API tokens.
◆ Current state
Currents is a Playwright/Cypress test observability platform that has made two explicitly agent-targeted moves in recent months: a shareable .md endpoint for test failures (structured failure context fetchable by AI agents without a Currents login) and a VS Code/Cursor extension that puts CI run history inside the IDE where AI agents can act on it. Personal Access Tokens — scoped per-user API tokens replacing the shared org key — just landed this week, addressing a real security gap in the API access model.
◆ Where it's heading
The product is converging on a position as the CI context layer for AI coding agents. Each major feature — shareable failure links with a .md format for agent consumption, IDE extension with agent-fix flow, Linear integration for structured failure triage — points at the same thesis: that CI failure remediation will increasingly be handled by AI agents, and Currents wants to be the system those agents pull context from. The pricing restructure (self-serve Business plan, cheaper per-user rates) lowers the entry barrier for teams adopting this agent-augmented workflow.
◆ Prediction
The IDE extension will likely expand to support more agentic actions beyond 'fix failure' — expect quarantine, tagging, and re-run controls. The .md shareable context format will likely become a formal API surface with authentication options for enterprise use.
