Opsis vs Hotjar: from heatmaps and recordings to reproduced, fixed bugs
Hotjar and Opsis sit at different stages of the same problem. Hotjar is heatmaps, session recordings and feedback for understanding what users do and where they struggle. Opsis is the QA layer that takes the broken sessions, reproduces them in a real browser, proves them on video, and writes the fix. Heatmaps point at the problem; Opsis resolves it.
At a glance
| Dimension | Opsis | Hotjar |
|---|---|---|
| Primary job | Find, prove & fix bugs | Heatmaps & session recordings |
| Session replay | Reads yours (Hotjar, SDK) | Records its own |
| Reproduces the bug in a browser | Yes, via Opsis MCP | – |
| Proof video of the failure | Yes | – |
| Hands you a copy-paste fix | Yes, per finding | – |
| Pre-deploy QA crawl | Yes, before-ship | – |
| Heatmaps (click / scroll / attention) | Yes (Pro+) | Yes |
| On-page feedback / surveys | No (not its job) | Yes |

What Hotjar is great at
Approachable heatmaps & recordings
Click, move and scroll heatmaps plus session recordings make Hotjar an easy, visual way to see where users engage and get stuck. For qualitative insight it's a popular, well-loved tool.
Feedback & surveys built in
On-page polls, feedback widgets and incoming feedback give you the 'why' behind the behaviour, rounding out the picture the recordings show.
A heatmap points at friction. It doesn't reproduce or fix the bug.
Hotjar shows you a red-hot zone of rage clicks or a recording of a stuck user; it doesn't tell you which session is a real defect, reproduce the failure in a browser, prove it on video, or write the fix. For marketers that's often enough; for engineers who need to ship a fix, the recording-to-fix gap is what Opsis closes.
How they fit together
Point Opsis at the sessions Hotjar records (or use the Opsis SDK). Opsis reads the friction signals, reproduces the strongest failures via Opsis MCP, proves each on video, and returns a guard-railed fix. Hotjar keeps heatmapping; Opsis turns the bad sessions into proven bugs with fixes.
When to use which
Use Hotjar
Reach for Hotjar when you want visual, qualitative insight: heatmaps, recordings, feedback and surveys to understand how users experience your site.
Use Opsis
Reach for Opsis when you need the broken sessions reproduced on video and fixed, rather than a heatmap pointing at where users struggle.
Together
Best together: Hotjar shows the heatmaps and feedback, Opsis reproduces the worst failures and writes the fixes.
Questions
Is Opsis a Hotjar alternative?
Opsis now ships its own heatmaps (Pro+) AND adds the reproduction/proof/fix layer Hotjar doesn't have. For on-page feedback and surveys, Hotjar still leads — but for closing the loop on a bug, Opsis is the one that reproduces and writes the fix.
Do I need Hotjar if I have Opsis?
Only if you want on-page feedback widgets and surveys. Opsis covers heatmaps (click, scroll, attention) and adds reproduction, proof, and a fix — the parts Hotjar doesn't do.
What does Opsis do that Hotjar doesn't?
Opsis reproduces a failure in a real browser via Opsis MCP, records proof video, and returns a guard-railed fix. Hotjar shows you the recording; it doesn't reproduce the bug or write the fix.
