What is Rootly?
Rootly pushes its AI incident agent from Slack into the core web app, on every incident
Rootly is executing an AI-native incident-response arc: after launching the @Rootly AI agent in Slack, it now embeds a chat agent on every incident in the web app, answering from live incident context. Around that, it is deepening operational depth — Cortex catalog sync, Intune-protected mobile, functionality-based paging, global on-call pay — spanning AI, enterprise mobility, and on-call economics.
What is Ably?
Ably is bending its realtime stack toward AI-agent transport
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.

Rootly pushes its AI incident agent from Slack into the core web app, on every incident
◆ Current state
Rootly is executing an AI-native incident-response arc: after launching the @Rootly AI agent in Slack, it now embeds a chat agent on every incident in the web app, answering from live incident context. Around that, it is deepening operational depth — Cortex catalog sync, Intune-protected mobile, functionality-based paging, global on-call pay — spanning AI, enterprise mobility, and on-call economics.
◆ Where it's heading
The direction is an AI agent that follows responders across every surface — Slack, mobile, and now the core web app — backed by live service context from integrations like Cortex. Alongside the AI bet, Rootly is hardening enterprise readiness (Intune, OAuth 2.0 for MCP) and on-call operations. The through-line is making the assistant, not the dashboard, the primary way responders interact with an incident.
◆ Prediction
Expect the web-app agent to gain more actions beyond Q&A (executing steps, drafting comms) and continued catalog and integration depth to feed it richer live context.

Ably is bending its realtime stack toward AI-agent transport
◆ Current state
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
◆ Where it's heading
The AI Transport SDK is where Ably is placing its directional bet: session/run models, branching conversations, human-in-the-loop handoff, and now external data hydration all point at owning the realtime layer for agent applications. In parallel the mainline JS client is formalizing React-first ergonomics and deprecating its v1 callback API.
◆ Prediction
Expect the AI Transport SDK to hold its rapid cadence toward a 1.0, and the newly released Dart SDK to follow the same early-adoption-to-stable path.
