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 Instatus?

Instatus has grown from status pages into a Slack-native incident response platform.

After launching Instatus 2.0 in mid-2025 with monitoring and incident response added to the existing status-page core, the past two quarters have been about polishing the incident lifecycle. The January release was the biggest expansion: full /incident command set in Slack, dedicated per-incident channels, postmortems from chat, and emoji-driven incident creation. Recent months added recurring maintenance windows, third-party status-page aggregation (Statuspage), General Notices, Freshstatus migration, Zapier, Jira, WhatsApp, Resend, and Brevo integrations.

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.

Instatus has grown from status pages into a Slack-native incident response platform.

◆ Current state

After launching Instatus 2.0 in mid-2025 with monitoring and incident response added to the existing status-page core, the past two quarters have been about polishing the incident lifecycle. The January release was the biggest expansion: full /incident command set in Slack, dedicated per-incident channels, postmortems from chat, and emoji-driven incident creation. Recent months added recurring maintenance windows, third-party status-page aggregation (Statuspage), General Notices, Freshstatus migration, Zapier, Jira, WhatsApp, Resend, and Brevo integrations.

◆ Where it's heading

The arc is clear: Instatus is going head-to-head with Atlassian's Statuspage and Better Stack on a single integrated stack — monitoring, incident response, public communication. The Slack-native push is the real differentiator; incident commanders rarely want to leave Slack. Migration tools (Freshstatus) and third-party aggregation (Statuspage import) point at land-and-expand against incumbents.

◆ Prediction

Expect on-call and scheduling integrations next, expanded migration tooling for other status-page incumbents (Better Stack, Status.io), AI-powered incident summarization and postmortems, and broader monitoring coverage — likely synthetic and browser checks.
