What is Stream?

Stream ships steady monthly polish across a wide logistics-ops surface

Stream is a delivery-management and route-planning platform shipping monthly compendium releases — every month touches planning, orders, vehicles, the driver mobile app, integrations, and the public API with customer-driven improvements. The May 2026 release adds automatic per-vehicle run costing; recent months added a Clients screen, an Operations Monitor, a mobile returns/collections flow, and parking-location coordinates. Texture is mature SaaS execution, not category bets.

What is Ably?

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

Stream ships steady monthly polish across a wide logistics-ops surface

◆ Current state

Stream is a delivery-management and route-planning platform shipping monthly compendium releases — every month touches planning, orders, vehicles, the driver mobile app, integrations, and the public API with customer-driven improvements. The May 2026 release adds automatic per-vehicle run costing; recent months added a Clients screen, an Operations Monitor, a mobile returns/collections flow, and parking-location coordinates. Texture is mature SaaS execution, not category bets.

◆ Where it's heading

Direction is breadth and depth on the existing surface, not expansion into a new category. Multi-language work recurs almost every release, pointing to a deliberate international push. The Public API gets touched nearly every month, suggesting integrations are how new logos land. Notably absent across the last ten releases: any AI or agent-integration features, which is unusual versus peer logistics tooling.

◆ Prediction

Next release should follow the same monthly compendium pattern — likely deeper financial/costing reporting (run costing was May's headline so adjacent surfaces logically follow), continued mobile-app polish for drivers, more public-API endpoints, and another round of multi-language coverage. No signal the cadence or scope is about to shift.

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

◆ Current state

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

◆ Where it's heading

The clear direction is extending Ably's pub/sub and LiveObjects primitives into agentic, real-time AI sessions — session/run models, branching conversations, and human-in-the-loop handoff. The mature client SDKs are being kept stable and incrementally improved while the AI transport layer is where new capability is concentrating.

◆ Prediction

Expect the AI Transport SDK to march toward a 1.0 with tighter integration of Presence and LiveObjects into agent sessions, while the core client libraries continue their fix-and-refine cadence.
