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 Chromatic?
Chromatic ships Vitest Browser Mode and React Native visual testing, moving beyond Storybook
Chromatic built its reputation as the visual testing and UI review layer for Storybook projects. Over the past year it expanded beyond that base: React Native testing on real iOS and Android simulators arrived in preview, Vitest Browser Mode shipped to GA in September 2026, and automatic flaky-test detection now keeps noise out of review queues. A Storybook MCP server publication shows it is also reaching into AI-assisted development pipelines.

Ably

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.
Chromatic

Chromatic ships Vitest Browser Mode and React Native visual testing, moving beyond Storybook
◆ Current state
Chromatic built its reputation as the visual testing and UI review layer for Storybook projects. Over the past year it expanded beyond that base: React Native testing on real iOS and Android simulators arrived in preview, Vitest Browser Mode shipped to GA in September 2026, and automatic flaky-test detection now keeps noise out of review queues. A Storybook MCP server publication shows it is also reaching into AI-assisted development pipelines.
◆ Where it's heading
Chromatic is repositioning from a Storybook-specific tool toward a framework-agnostic visual testing platform. The Vitest GA and React Native preview are its two clearest bets: one follows the shift in component testing toward Vitest, the other opens the mobile market. Publishing MCP servers for Storybook suggests it sees AI code generation as a distribution channel worth owning early.
◆ Prediction
Vitest Browser Mode will likely reach feature parity with Storybook support — shared dashboards, unified pricing, combined trend data — within two quarters. React Native visual testing exits preview when Chromatic solves simulator reliability at scale.
