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 Novu?
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.

Ably
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.
Novu
2.1INFRA · APIS
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
◆ Current state
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.
◆ Where it's heading
Novu is positioning as a notification platform an AI agent can drive end-to-end and a developer can wire from code, with the dashboard becoming optional. The MCP Server GA codifies that pitch publicly. Expect more tools exposed over MCP and continued depth on tenant scoping, since multi-tenant SaaS is the main buyer.
◆ Prediction
The next directional move likely formalizes agent-built workflows as first-class artifacts with versioning and approval, so AI-authored notifications can survive review. Slack and other chat integrations should leave beta and join the standard provider list.
