Hotjar vs Resend: at a glance
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 Resend?
Resend is making itself the email primitive agents reach for, then hardening the audit surface.
Small, frequent changelog entries split cleanly in two. One half is agent-facing distribution: the remote MCP server moved to the stateless 2026-07-28 spec and a Resend plugin now ships through the Codex marketplace. The other half fills operational gaps — suppression lists in dashboard and API, automatic detection and revocation of leaked keys, and an editor that flags HTML likely to break in email clients.

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.
Resend
5.0INFRA · APIS
Resend is making itself the email primitive agents reach for, then hardening the audit surface.
◆ Current state
Small, frequent changelog entries split cleanly in two. One half is agent-facing distribution: the remote MCP server moved to the stateless 2026-07-28 spec and a Resend plugin now ships through the Codex marketplace. The other half fills operational gaps — suppression lists in dashboard and API, automatic detection and revocation of leaked keys, and an editor that flags HTML likely to break in email clients.
◆ Where it's heading
After OAuth landed in July, the work has shifted from authorizing agents to being reachable from wherever they run — MCP, Codex, a Claude connector. Behind that, the dashboard is acquiring the controls a buyer inspects during review: who was suppressed, what leaked, what will render. Nothing here is large on its own; the cadence is the point.
◆ Prediction
Expect distribution into more agent surfaces and deeper suppression and deliverability reporting; the compatibility checker suggests more authoring-time validation of templates.
