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 Skipper?
Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

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.
Skipper
7.5INFRA · APIS
Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
◆ Current state
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.
◆ Where it's heading
The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.
◆ Prediction
The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
