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 OpenStatus?
OpenStatus adds heartbeat monitors for cron jobs that fail without a sound.
OpenStatus can now watch cron jobs, backups and workers through heartbeat monitors: a job pings a unique URL, and OpenStatus alerts when the pings stop or report a failure. Status pages can also show uptime bars and timestamps in their own time zone rather than UTC. These follow per-resource API scopes, MCP setup tools and October's incident-management work.

◆ 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.
OpenStatus
5.0INFRA · APIS
OpenStatus adds heartbeat monitors for cron jobs that fail without a sound.
◆ Current state
OpenStatus can now watch cron jobs, backups and workers through heartbeat monitors: a job pings a unique URL, and OpenStatus alerts when the pings stop or report a failure. Status pages can also show uptime bars and timestamps in their own time zone rather than UTC. These follow per-resource API scopes, MCP setup tools and October's incident-management work.
◆ Where it's heading
OpenStatus is widening from checking endpoints from the outside to catching background work that fails silently, while finishing off its incident and status-page flow.
◆ Prediction
Heartbeat monitors will probably be wired into the incident flow and MCP tools next, as earlier monitor and incident features were.
