What is Ably?
Ably is repositioning realtime infrastructure as AI-agent infrastructure.
Ably's last two months read like a deliberate pivot: the CLI shipped its stable 1.0 with agent-shaped affordances (structured JSON envelopes, error hints for self-healing, --force gates on destructive ops), 1.1 added a one-command init that drops Ably's skills bundle directly into Claude Code, Cursor, Windsurf, and VS Code, and the AI Transport SDK landed with tool-calling support and Vercel AI SDK integration. Around that, a new Dart SDK gives the pub/sub core a Flutter front door, and LiveObjects moved from preview to GA on the JS client.
What is Rootly?
Rootly opens itself to AI agents as first-class operators
Rootly is a mature incident-management and on-call platform that has decided AI agents are the next user persona to design for. Recent releases pair first-party IDE plugins (Claude Code, Cursor) and standardized agent auth (MCP over OAuth 2.0) with steady operational depth — deferred paging, live alerts, team-scoped heartbeats, SLA-driven follow-ups. The human SRE surface still gets attention even as the agent surface gets built out.

Ably is repositioning realtime infrastructure as AI-agent infrastructure.
◆ Current state
Ably's last two months read like a deliberate pivot: the CLI shipped its stable 1.0 with agent-shaped affordances (structured JSON envelopes, error hints for self-healing, --force gates on destructive ops), 1.1 added a one-command init that drops Ably's skills bundle directly into Claude Code, Cursor, Windsurf, and VS Code, and the AI Transport SDK landed with tool-calling support and Vercel AI SDK integration. Around that, a new Dart SDK gives the pub/sub core a Flutter front door, and LiveObjects moved from preview to GA on the JS client.
◆ Where it's heading
The strategic narrative is converging fast: Ably wants to be the realtime layer agents reach for by default. Each release reinforces the same thesis — the CLI is becoming an agent-operable surface; the AI Transport SDK is becoming the channel for tool calls and streaming reasoning; the skills bundles are becoming the on-ramp inside whichever AI coding tool the developer already uses. The classic pub/sub product still ships SDKs and protocol upgrades, but the editorial energy is on the agent track.
◆ Prediction
Expect the Agent Skills bundle to keep widening — more tools beyond the current four IDEs, and richer skills that wrap LiveObjects and chat. The AI Transport SDK is still 0.1, so expect a 1.0 push with stable contracts for tool approval, streaming, and observability. Pricing and packaging conversations around AI workloads (per-tool-call billing? agent-tier plans?) are the obvious next thing to watch for.

Rootly opens itself to AI agents as first-class operators
◆ Current state
Rootly is a mature incident-management and on-call platform that has decided AI agents are the next user persona to design for. Recent releases pair first-party IDE plugins (Claude Code, Cursor) and standardized agent auth (MCP over OAuth 2.0) with steady operational depth — deferred paging, live alerts, team-scoped heartbeats, SLA-driven follow-ups. The human SRE surface still gets attention even as the agent surface gets built out.
◆ Where it's heading
The product is shifting from 'humans on-call with integrations' toward 'humans and agents operating side by side.' MCP OAuth is the structural enabler: short-lived, scoped tokens replace long-lived API keys, which is the prerequisite for letting an agent take actions in production without exposing credentials. The IDE plugins are the distribution side of the same bet — meet the SRE where they already work. Operational releases keep landing in parallel, so the human on-call experience is not being neglected.
◆ Prediction
Expect deeper agent-action coverage next — moving from 'agents can read incidents' to 'agents can run runbooks, post status updates, and modify tickets' with audit trails tied to OAuth-scoped tokens. The plugin surface likely grows beyond Claude Code and Cursor.
