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.

What is Ably?

Ably is spinning up an AI-agent transport layer at 0.x speed

Ably is iterating hard on a new AI Transport SDK — four releases (0.2 through 0.5) in about a month — aimed at making agent conversations durable, resumable, and branchable over its realtime channels. Alongside it, the core Pub/Sub and Chat SDKs keep getting steady, mostly incremental maintenance: React hook ergonomics, presence reliability fixes, and better LiveObjects visibility in the dashboard.

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.

Ably is spinning up an AI-agent transport layer at 0.x speed

◆ Current state

Ably is iterating hard on a new AI Transport SDK — four releases (0.2 through 0.5) in about a month — aimed at making agent conversations durable, resumable, and branchable over its realtime channels. Alongside it, the core Pub/Sub and Chat SDKs keep getting steady, mostly incremental maintenance: React hook ergonomics, presence reliability fixes, and better LiveObjects visibility in the dashboard.

◆ Where it's heading

The AI Transport line is the story. Each release layers on capability that matters for production agents — declarative codecs, external data hydration, and now durable execution that survives process restarts inside frameworks like Temporal and Vercel's WDK. Ably is positioning its realtime infrastructure as the transport substrate for AI agents, not just chat and pub/sub, while keeping the mature core SDKs stable. The frequent breaking changes signal a product still finding its API shape.

◆ Prediction

Expect the AI Transport SDK to keep its fast breaking-change cadence toward a 1.0 with a stabilized session/run API, and likely SDKs beyond JS as the surface settles. The entries don't yet indicate a GA date.
