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 Sentry?

Sentry is pushing past collection into interpretation, with Seer and AI-generated dashboards.

Two AI surfaces now anchor the changelog: the Seer agent in open beta and an AI dashboard-generation beta. Underneath, the platform keeps broadening ingestion and alerting — metrics reach .NET and Unity, logs reach Kotlin Multiplatform, uptime monitors gain alert configuration, metrics beta gains alerting, and Alerts is splitting into Monitors and Alerts. Size Analysis and org-level Data Forwarding reached GA.

Ably vs Sentry: editorial side-by-side

7.5

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.

Sentry is pushing past collection into interpretation, with Seer and AI-generated dashboards.

◆ Current state

Two AI surfaces now anchor the changelog: the Seer agent in open beta and an AI dashboard-generation beta. Underneath, the platform keeps broadening ingestion and alerting — metrics reach .NET and Unity, logs reach Kotlin Multiplatform, uptime monitors gain alert configuration, metrics beta gains alerting, and Alerts is splitting into Monitors and Alerts. Size Analysis and org-level Data Forwarding reached GA.

◆ Where it's heading

The consistent direction is reducing the setup and expertise required before a signal becomes visible. Generating dashboards and answering questions about the app are both attacks on the same cost: the engineer who has to know what to build before they can see anything. Meanwhile SDK and alerting coverage keeps filling in as table stakes.

◆ Prediction

Look for the AI surfaces to converge — Seer and generated dashboards becoming one investigation path rather than two features — and for the Monitors/Alerts split to settle into clearer routing.
