What is Hotjar?
Hotjar's update feed stops in April 2025 — the arc it captures ended mid-sentence.
Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.
What is Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

Hotjar's update feed stops in April 2025 — the arc it captures ended mid-sentence.
◆ Current state
Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.
◆ Where it's heading
The direction visible in these entries is a move up the research stack — from watching what users did on a live site toward asking them questions and testing designs before they ship. User Tests removed the moderator, AI tagging removed the manual sorting of open-ended responses, and prototype testing removed the requirement that the thing being tested exist yet. Each step cut a person out of the research loop. Whether that arc continued past April 2025 is not something this feed can answer.
◆ Prediction
No prediction is supportable from these entries. The feed has published nothing for over a year, so any claim about Hotjar's current direction would be invented rather than observed — the only honest read is that this channel has been abandoned or moved elsewhere.
Knock
6.3INFRA · APIS
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
