What is Ably?
Ably graduates LiveObjects to stable across Java and iOS SDKs, completing its real-time state-sync layer for AI agent deployments.
Ably has spent the past two months landing its LiveObjects feature—a path-based API for managing fast-changing shared state—across its major client SDKs. Java SDK v1.8.1 marks the last major platform leaving experimental, following the Cocoa/Swift SDK in early September. In parallel, the AI Transport JS SDK has grown Temporal workflow support and Vercel AI SDK v7 compatibility, and the Terraform provider reached v1.1.0 with significant new surface area including moderation rules and before-publish hooks.
What is Cursor?
Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.
Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.

Ably
6.3INFRA · APIS
Ably graduates LiveObjects to stable across Java and iOS SDKs, completing its real-time state-sync layer for AI agent deployments.
◆ Current state
Ably has spent the past two months landing its LiveObjects feature—a path-based API for managing fast-changing shared state—across its major client SDKs. Java SDK v1.8.1 marks the last major platform leaving experimental, following the Cocoa/Swift SDK in early September. In parallel, the AI Transport JS SDK has grown Temporal workflow support and Vercel AI SDK v7 compatibility, and the Terraform provider reached v1.1.0 with significant new surface area including moderation rules and before-publish hooks.
◆ Where it's heading
Ably is building toward becoming the real-time infrastructure layer for agentic AI systems: LiveObjects handles shared state across multiple agents; the AI Transport SDK handles the run lifecycle (turn framing, Temporal orchestration); the new E2E encryption for annotation payloads closes a security gap in the model. The direction is away from general-purpose pub/sub toward targeted infrastructure that connects AI agents to each other and to human-facing interfaces.
◆ Prediction
The next likely move is developer experience work around multi-agent state coordination—LiveObjects is now stable but production wiring patterns are probably still rough. Expect documentation, example patterns, and possibly a managed agent-state abstraction built on top of the stable API.
Cursor
8.8INFRA · APIS
Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.
◆ Current state
Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.
◆ Where it's heading
Every release since mid-2026 has added a new layer of the autonomous-software-pipeline stack: code hosting (Origin Repos), always-on event-driven agents (Subscriptions), parallel subagent execution (team pools, per-VM isolation), and now a coordinator agent that owns long-running Projects end-to-end. The pattern is consistent — each release removes a human touchpoint that previously required manual intervention.
◆ Prediction
The next move is likely billing and governance for agent-compute at scale. Projects running thousands of parallel subagents implies compute costs that don't fit per-seat pricing; enterprise contracts around agent-hours or compute credits are the natural next step, especially with the self-hosted pool infrastructure already in place.
