What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
What is RSS-Bridge?
RSS-Bridge resurfaces after a year with a date tag and a Bluesky fix, but no release notes.
RSS-Bridge generates feeds for sites that dropped theirs, and its releases are batches of community fixes to individual site bridges plus a few new ones. The last documented release was 2025-08-05. A new 2026-09-30 tag has appeared whose only visible change is a Bluesky bridge null-handling fix, with no published notes alongside it.

Ably
7.5INFRA · APIS
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
RSS-Bridge
0.0INFRA · APIS
RSS-Bridge resurfaces after a year with a date tag and a Bluesky fix, but no release notes.
◆ Current state
RSS-Bridge generates feeds for sites that dropped theirs, and its releases are batches of community fixes to individual site bridges plus a few new ones. The last documented release was 2025-08-05. A new 2026-09-30 tag has appeared whose only visible change is a Bluesky bridge null-handling fix, with no published notes alongside it.
◆ Where it's heading
The core is stable PHP and the work lives in the roughly 400 site-specific scrapers, which break whenever a target site changes markup or adds bot protection. Releases have slowed from every few months to once a year, so maintenance is continuing on master faster than it is being packaged.
◆ Prediction
Unclear from the feed whether 2026-09-30 will get a written release; if it does, expect the usual mix of bridge repairs and bot-protection workarounds.
