coldrun
An AI stranger tries your landing page, then reports back.
Hey Indie Hackers👋
I kept doing the same thing by hand for every product I worked on: open the landing page in an incognito window and try to forget everything I know about it, just to see where a stranger would actually get stuck. It never really works — you can't unsee your own product.
So coldrun does that literally: an AI agent with genuinely no prior knowledge of your product opens your URL, finds what it thinks is the primary call-to-action, clicks it once, and narrates its reasoning the whole way — what it read, what it expected next, where it hesitated. You get a scored report back, not just a bounce-rate number.
It's free, one audit per account right now while I get real usage data. Here's a real one we ran on our own landing page: https://coldrun.app/example-audit
Would love feedback — especially if the report tells you something you didn't already suspect, or if it completely misses something obvious. Both are useful to me today.

I'm just in launching phase currently that's why there is a free report per account for landing pages. There are no reports yet done by the users, so I don't have real data on this, but we give an export to pdf option which you can directly send to a coding agent like Claude Code or Codex and it will run the fixes. Later I am planning to implement some features to re-audit the page after you have done the fixes.
I would really appreciate if you tried it out in the first-hand, its free no credit card required and only one app link is the input you give it. Thank you for your curiosity too.
