Microsoft Clarity and FullStory record real visitors on your live site: session replays, heatmaps and signals like rage clicks. Clarity is free; FullStory adds deeper analytics for larger teams.
Prior.Run does a different job. It runs your page — live or still a prototype — and hands back a Run Sheet: every problem pinned to the spot, with the change to make.
Side by side
Here is what each one is for.
— Side by side
Works before launch
A Run works on a prototype or unlaunched page. Replay needs real visitors.
No traffic needed
Paste a link and go. Replays fill up as visitors arrive.
Every button and form tried
A Run tries every path. Visitors only use the parts they care about.
The fix, not just the problem
Each finding comes with the change to make. With replays, you work it out.
Real visitors at scale
Thousands of real sessions are what session replay is for.
— Pick by the question you need answered, not by the tool.
What session replay does well
It shows real behavior at scale. You can see where real visitors click, where they get stuck and where they give up — across thousands of sessions.
Where it runs out
It needs traffic, so the page has to be live and the problems are already costing you. And someone still has to watch the replays, work out what went wrong and decide what to change.
What a Run does
Our panel opens your page on desktop or a phone and uses all of it: every button, every tab, every form, down the main path and then the others. It fills forms with test details and stops before anything that costs money.
In under an hour you get a Run Sheet. Each finding sits on the spot where it happened, sorted from fix first to keep, with why it matters and the change to make. Open the page and check any of it in seconds.
— VERDICT
Run it before launch. Replay it after.
Run the page before it goes live and fix what the Run Sheet pins. Then use Clarity or FullStory to see how real visitors use the fixed version.
