What is Hotjar?
Hotjar steadily widens its survey and user-research surface, but recent updates are thin on detail.
Hotjar's last three updates (auto-tag survey responses, custom survey button labels, invite respondents to interviews) all sit in the Surveys/Ask/Engage product line, suggesting research workflows are the active investment area. Source content is sparse — the recent entries scraped as just 'Copy link' titles — but the URL slugs and historical pattern paint a consistent picture.
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.

Hotjar
1.3INFRA · APIS
Hotjar steadily widens its survey and user-research surface, but recent updates are thin on detail.
◆ Current state
Hotjar's last three updates (auto-tag survey responses, custom survey button labels, invite respondents to interviews) all sit in the Surveys/Ask/Engage product line, suggesting research workflows are the active investment area. Source content is sparse — the recent entries scraped as just 'Copy link' titles — but the URL slugs and historical pattern paint a consistent picture.
◆ Where it's heading
Hotjar is broadening from session recording and heatmaps into a full qualitative research stack: surveys with AI-assisted tagging, user tests, prototype testing, and live interview recruitment. The arc points toward an end-to-end research platform inside one tool, competing more directly with UserTesting, Maze, and Dovetail than with pure analytics tools.
◆ Prediction
Expect the next releases to either expose AI-summarization of survey/interview data or a more integrated handoff between surveys and recordings — closing the loop between 'who said what' and 'what they actually did.' The scrape quality of recent updates also needs to improve before this changelog is genuinely informative.
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.
