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 Uptrends?

Uptrends spent October on account plumbing: vault credentials, bulk edits and a free trial path.

Uptrends is a synthetic and API monitoring service. October releases were mostly account and workflow items: credentials for authenticated monitors can now live in a shared vault instead of plain text, monitors can be bulk-edited with a preview of the credit impact, HTTPS and multi-step API monitors support the HTTP QUERY method, and free accounts can start a 30-day Enterprise trial. SCIM provisioning for Enterprise accounts arrived in late September, and e-invoices joined PDF billing.

Ably vs Uptrends: 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.

Uptrends spent October on account plumbing: vault credentials, bulk edits and a free trial path.

◆ Current state

Uptrends is a synthetic and API monitoring service. October releases were mostly account and workflow items: credentials for authenticated monitors can now live in a shared vault instead of plain text, monitors can be bulk-edited with a preview of the credit impact, HTTPS and multi-step API monitors support the HTTP QUERY method, and free accounts can start a 30-day Enterprise trial. SCIM provisioning for Enterprise accounts arrived in late September, and e-invoices joined PDF billing.

◆ Where it's heading

Two threads continue. Monitors are being made to behave like real API clients: after bearer tokens and JWT functions, HTTP QUERY lets a monitor send long search bodies without URL limits. The account side is being prepared for larger and more regulated customers: SCIM, vault-stored credentials and e-invoicing all serve procurement and IT rather than the person writing checks. The Enterprise trial for free accounts is the first entry here aimed at converting small users upward.

◆ Prediction

Existing monitors keep plain-text credentials until edited, so expect a migration prompt or bulk action to move them into the vault. Enterprise remains the tier that receives new capabilities first, as SCIM did.
