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 RSS-Bridge?
The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.
RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

Ably
7.5INFRA · APIS
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.
RSS-Bridge
0.0INFRA · APIS
The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.
◆ Current state
RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.
◆ Where it's heading
The project has been shifting from a curated tool to a general-purpose scraping surface: bridges are now all enabled by default, caching was rewritten, and token-based URL auth was added to make public instances survivable. That combination points at operators running shared instances rather than individuals running one bridge. The maintenance load, however, is entirely community-carried, and the gap since the last release suggests that pipeline has thinned.
◆ Prediction
The next release is likely another routine batch of bridge repairs and additions rather than a core change. The stated intentions in these notes — raising the minimum PHP version and separating the document root from the data folder — remain unshipped, and nothing here indicates when that lands.
