What is Rootly?
Rootly is systematically building an AI agent across the full incident lifecycle.
Rootly has shipped a steady stream of AI-driven incident management capabilities over the past six weeks: proactive related-incident detection, live call transcription with speaker labels, ServiceNow CMDB sync, Slack Canvas workflow integration, and the Rootly Agent extended to mobile. The through-line is consistent — reduce manual work at every stage of an incident without requiring responders to leave Slack.
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.

Rootly is systematically building an AI agent across the full incident lifecycle.
◆ Current state
Rootly has shipped a steady stream of AI-driven incident management capabilities over the past six weeks: proactive related-incident detection, live call transcription with speaker labels, ServiceNow CMDB sync, Slack Canvas workflow integration, and the Rootly Agent extended to mobile. The through-line is consistent — reduce manual work at every stage of an incident without requiring responders to leave Slack.
◆ Where it's heading
Rootly is building toward a complete AI agent for incident response: gather evidence automatically, transcribe every call, surface past incidents before anyone searches, sync your catalog, and update stakeholders in the channels they already use. The evidence-gathering feature (across observability, code, infra, feature flags, ticketing, and docs) released in late July is the architectural foundation — everything since layers on top of that read-only integration surface.
◆ Prediction
The next moves will likely deepen the AI agent's ability to act, not just observe — auto-drafting postmortems, suggesting runbook steps, or driving resolution workflows. The mobile footprint enables responders to act from anywhere, which opens use cases for on-call response speed.

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.
