What is Rootly?
Rootly is wiring an AI incident commander into Slack and the editors engineers already use
Rootly keeps building out on-call and incident management — deferred paging, team-scoped heartbeats, SLA-driven follow-ups, live alert streaming — while layering an AI agent across the surfaces responders already live in. The June launch of an in-Slack AI scribe and commander is the sharpest expression of that bet.
What is Ably?
Ably is rebuilding its realtime stack around AI agents: transport SDK and agent-native CLI
Ably is repositioning its realtime messaging infrastructure around AI agents. The clearest evidence is a dedicated AI Transport SDK, now with a session/run model, conversation branching, and human-in-the-loop handoff, plus a CLI rebuilt to be agent-operable that installs Agent Skills into Claude, Cursor, and Windsurf and emits structured JSON for self-healing automation. Underneath, the core Pub/Sub and Chat SDKs keep maturing and platform reach widens with a new Dart/Flutter SDK.

Rootly is wiring an AI incident commander into Slack and the editors engineers already use
◆ Current state
Rootly keeps building out on-call and incident management — deferred paging, team-scoped heartbeats, SLA-driven follow-ups, live alert streaming — while layering an AI agent across the surfaces responders already live in. The June launch of an in-Slack AI scribe and commander is the sharpest expression of that bet.
◆ Where it's heading
Two threads run in parallel: steady RBAC-and-reliability hardening of the core on-call product, and an AI push that meets responders in Slack, in editors (Claude Code, Cursor), and via MCP with proper OAuth. The direction is an agent that handles incident toil where work already happens.
◆ Prediction
Expect the Slack agent's commander/scribe role to deepen — more autonomous actions during incidents and tighter ties to the MCP and editor plugins — while core on-call features keep filling RBAC and SLA gaps.

Ably is rebuilding its realtime stack around AI agents: transport SDK and agent-native CLI
◆ Current state
Ably is repositioning its realtime messaging infrastructure around AI agents. The clearest evidence is a dedicated AI Transport SDK, now with a session/run model, conversation branching, and human-in-the-loop handoff, plus a CLI rebuilt to be agent-operable that installs Agent Skills into Claude, Cursor, and Windsurf and emits structured JSON for self-healing automation. Underneath, the core Pub/Sub and Chat SDKs keep maturing and platform reach widens with a new Dart/Flutter SDK.
◆ Where it's heading
The trajectory is realtime-as-agent-infrastructure: the AI Transport SDK is iterating fast toward production agent apps with branching, suspend/resume, and tool-calling, while the tooling is built so AI coding agents, not just humans, can drive Ably. The conventional SDK and CLI work continues in parallel, but the directional energy is clearly aimed at the agent stack.
◆ Prediction
Expect the AI Transport SDK to keep adding agent-conversation primitives on its march to 1.0, and the Dart SDK to fill toward parity with the JS line.
