What is Ably?
Ably is bending its realtime stack toward AI-agent transport
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
What is Bugsnag?
BugSnag is compounding on mobile observability and AI-assisted debugging
BugSnag ships on a predictable monthly cadence, and the throughline is clear: deeper mobile and cross-platform performance monitoring (Flutter system metrics, iOS pre-main app starts) alongside a steadily expanding self-hosted MCP server for AI-assisted error resolution. Recent months added correlated events, side-by-side span comparison, and app-hang detection.

Ably is bending its realtime stack toward AI-agent transport
◆ Current state
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
◆ Where it's heading
The AI Transport SDK is where Ably is placing its directional bet: session/run models, branching conversations, human-in-the-loop handoff, and now external data hydration all point at owning the realtime layer for agent applications. In parallel the mainline JS client is formalizing React-first ergonomics and deprecating its v1 callback API.
◆ Prediction
Expect the AI Transport SDK to hold its rapid cadence toward a 1.0, and the newly released Dart SDK to follow the same early-adoption-to-stable path.

BugSnag is compounding on mobile observability and AI-assisted debugging
◆ Current state
BugSnag ships on a predictable monthly cadence, and the throughline is clear: deeper mobile and cross-platform performance monitoring (Flutter system metrics, iOS pre-main app starts) alongside a steadily expanding self-hosted MCP server for AI-assisted error resolution. Recent months added correlated events, side-by-side span comparison, and app-hang detection.
◆ Where it's heading
Two investments dominate — broadening platform performance coverage (Flutter, iOS startup, Vue) and building out the MCP server as connective tissue between BugSnag data and AI debugging tools. The product is moving from 'see your errors' toward 'resolve them with an agent.'
◆ Prediction
Expect continued MCP capability growth and more first-class performance monitoring for additional runtimes, likely surfacing more AI-driven remediation actions inside the dashboard.
