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 Kaniko?

Kaniko's release feed stops dead in June 2024 after a patch that undid its own change

Kaniko builds container images inside a container without a Docker daemon, and its release feed reads as a project in late-stage maintenance that then simply stopped. Every entry in this window carries the same boilerplate header of executor, debug and slim image tags, and underneath it the substance is dependency bumps, CVE-driven upgrades, and narrow fixes to ADD and COPY semantics. The last release here, v1.23.1, is a revert of behaviour changed weeks earlier plus documentation clarifying what the flag was supposed to do.

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.

Kaniko's release feed stops dead in June 2024 after a patch that undid its own change

◆ Current state

Kaniko builds container images inside a container without a Docker daemon, and its release feed reads as a project in late-stage maintenance that then simply stopped. Every entry in this window carries the same boilerplate header of executor, debug and slim image tags, and underneath it the substance is dependency bumps, CVE-driven upgrades, and narrow fixes to ADD and COPY semantics. The last release here, v1.23.1, is a revert of behaviour changed weeks earlier plus documentation clarifying what the flag was supposed to do.

◆ Where it's heading

The cadence tells the story: nine releases between December 2023 and June 2024, then nothing at all in the two years since. Even during the active stretch the work was defensive — registry-map compatibility, ECR authentication breakage, tar.gz handling in ADD, vulnerability scanning added to the executor image — rather than any expansion of what Kaniko does. The one recurring theme with forward motion, registry mirror and registry-map support, was about surviving locked-down or mirrored registry environments.

◆ Prediction

Nothing in these entries points at planned work, and a two-year gap after a revert-and-document patch is the signature of a project no longer being released; anyone depending on it should assume the last published executor image is the last one.
