Ably Launches AI Transport Infrastructure Layer for Seamless Multi-Device Agent Experiences

Summary

Ably has introduced Ably AI Transport, a new infrastructure layer designed specifically for AI agents and conversational experiences. The platform provides durable, steerable, and multi-device capabilities without requiring developers to rebuild their entire stack. Key features include resumable streaming across device reloads and network failures, real-time synchronization across multiple devices and tabs, live steering and interrupt capabilities, and support for multi-agent collaboration with full context preservation.

Unlike traditional HTTP streaming approaches that struggle with long-running, stateful AI interactions, Ably AI Transport uses a global WebSocket network to deliver ordered, bi-directional, low-latency state management. The platform enables continuous conversations with visible agent progress, tool-calling integration, and seamless human takeover capabilities. Early adoption includes integration with Meta's Messenger and Fin products, as well as deployment in HubSpot's AI assistant, where it provides reliable, low-latency performance for production AI experiences.

Editorial Opinion

Ably AI Transport addresses a genuine infrastructure gap in the AI agent ecosystem—the challenge of delivering seamless, multi-device experiences without significant engineering overhead. As AI applications grow more sophisticated and stateful, traditional request-response patterns become increasingly inadequate. This product hits the market at the right moment when enterprises are building serious conversational AI products and need reliable, low-latency transport layers. However, adoption will likely depend on how effectively Ably can integrate with diverse AI stacks and frameworks that are still rapidly evolving.
