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 Buildkite?
Buildkite ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week
Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.

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.

Buildkite ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week
◆ Current state
Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.
◆ Where it's heading
Two threads are running in parallel: hardening the core agent (v4, ephemeral job acquisition tokens, 1 GiB log quota) and expanding the agentic surface (MCP tools for secrets, test attribution, step uploads, failure summaries). The VS Code extension opens a third front — IDE-native CI — that no major CI platform currently owns. The combination points toward Buildkite positioning as infrastructure for AI-driven developer workflows, not just pipeline execution.
◆ Prediction
The MCP server will keep acquiring write operations — secret creation is already there, pipeline modification is the next logical step. The VS Code extension will likely gain pipeline creation and editing to close the IDE-native CI loop.
