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.
What is FireHydrant?
FireHydrant pairs a steady polish cadence with a real expansion move: a live EU instance.
FireHydrant ships dense monthly recaps spanning incident response, on-call scheduling, Signals alerting, status pages, retrospectives, and mobile. The recent work is heavy on usability — a rebuilt Teams directory and detail page, smarter on-call schedule filtering, deeper incident analytics (session-based involvement metrics) — backed by a long tail of bug fixes that signal a maturing, broadly deployed product.

Ably
6.3INFRA · APIS
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.
FireHydrant
5.0INFRA · APIS
FireHydrant pairs a steady polish cadence with a real expansion move: a live EU instance.
◆ Current state
FireHydrant ships dense monthly recaps spanning incident response, on-call scheduling, Signals alerting, status pages, retrospectives, and mobile. The recent work is heavy on usability — a rebuilt Teams directory and detail page, smarter on-call schedule filtering, deeper incident analytics (session-based involvement metrics) — backed by a long tail of bug fixes that signal a maturing, broadly deployed product.
◆ Where it's heading
Two threads stand out: regional expansion via a fully operational EU instance, and AI woven through the workflow (related-incident detection, audience-tailored summaries, MS Teams transcription via Scribe). The product is consolidating analytics into a single MTTX dashboard and steadily reaching parity with incumbent paging tools on enterprise controls.
◆ Prediction
Expect the EU instance to anchor a push for European enterprise and compliance-sensitive accounts, and continued AI investment around incident summaries and related-incident detection.
