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 Glide?
Glide's cadence has thinned post-Agent-launch, with recent work focused on Data Editor polish.
After putting Glide Agent into beta in September 2025, the product entered a quiet stretch broken up by multi-month 'general updates' digests. The most recent April release returns to the Data Editor — adding filter, sort, and search that work uniformly across Glide Tables, Big Tables, and external data sources — rather than expanding the agent surface.

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.
Glide
0.8INFRA · APIS
Glide's cadence has thinned post-Agent-launch, with recent work focused on Data Editor polish.
◆ Current state
After putting Glide Agent into beta in September 2025, the product entered a quiet stretch broken up by multi-month 'general updates' digests. The most recent April release returns to the Data Editor — adding filter, sort, and search that work uniformly across Glide Tables, Big Tables, and external data sources — rather than expanding the agent surface.
◆ Where it's heading
The Glide Agent positioning from late 2025 was a clear pivot toward natural-language app generation, but follow-through is slow. Recent work focuses on core-editor ergonomics, enterprise plumbing (folder permissions, SSO, admin-only invites), and broadening the integration surface (Snowflake, QuickBooks, Salesforce, OpenRouter's 300+ models). The product reads as in a consolidation phase rather than an active push.
◆ Prediction
If Agent remains the strategic bet, expect a return to AI-driven app-generation features later in 2026 — likely tighter Agent + Workflow chaining and richer multi-model selection. Otherwise the cadence suggests settling into incremental enterprise integration work, with no-code rivals (Bubble, Softr, Adalo) continuing to apply pressure.
