Every CRO tool CROW has

Eight of them, and they are not eight of the same thing. Two audit a page and then put the fix on your live site. The other six give you an answer that you go and act on yourself. That difference is the whole product, so this page is ordered by it rather than alphabetically.

All eight are free to run — 3 runs a day across the whole set — and none of them need an account. You only sign up when you want CROW to deploy a fix for you.

These two change your site

They audit the page, write the fix, show it to you on your own page first, and ship it through one script tag when you say so. Nothing goes live without you pressing something.

These six tell you what to change — you do it

Standalone, free, and none of them touch your site or need a script tag. Each one answers a single question and hands you the answer.

Why the top two matter more than the other six: if your site doesn’t have the traffic to A/B test, a list of suggestions is where most tools leave you — and shipping the change is the only part that ever moves anything.
