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 Shuffle?

Shuffle tags builds almost daily, but the notes are empty.

Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.

Ably vs Shuffle: editorial side-by-side

A

INFRA · APIS
7.5

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.

5.0

Shuffle tags builds almost daily, but the notes are empty.

◆ Current state

Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.

◆ Where it's heading

The project is iterating toward 2.3.1 with frequent builds, and the October notes show the work is about making AI agent steps run reliably in workflows. The empty release notes make it hard to see what each build changes.

◆ Prediction

A 2.3.1 final release looks close given the run of release candidates and nightlies, though the entries do not say what it will contain beyond fixes.
