Free AI UX roast

Roast my website.

An AI agent uses your site like a first-time visitor and roasts everything that trips it up, with a screenshot for every complaint. A real browser session, not a screenshot pasted into ChatGPT.

Roast your own site or a competitor’s · no login, no card required · takes about 2 minutes

Most "AI website roast" tools paste a single screenshot into a language model and hand you back fifteen confident guesses. That misses about half of what's actually wrong, because half of a website's UX failures only appear when something gets *used*: a form submitted, an error triggered, a second page loaded. When Baymard put screenshot-only reviews to the test, they caught 14% of real issues and were wrong 80% of the time.

ClapBack puts Claude Opus in a real headless browser. It scrolls, clicks, and reads your site like a stranger who has never seen it before, then reports each problem with the screenshot that proves it and the named usability rule it breaks. You can verify any finding in a few seconds instead of taking our word for it.

What the roast looks for on a website

Nielsen · Visibility of system status

First-impression clarity

Can a stranger tell what you do and what to do next within five seconds? Vague hero copy and mystery-meat navigation are the most common reasons visitors bounce before they ever scroll.

WCAG 2.2 · 1.4.3 Contrast

Contrast & readability

83.9% of the top million home pages ship text that fails WCAG AA contrast. Gray-on-gray body copy and low-contrast buttons cost you the users who most need to read them.

Fitts's Law · Laws of UX

Tap targets & mobile layout

Buttons too small to hit, content that overflows on a phone, a menu that hides your primary action. The roast walks the mobile layout, not just the desktop one.

Nielsen · Error prevention

Forms that don't fight you

It submits your forms empty, with junk, and correctly, hunting for missing labels, silent validation failures, and dead ends that lose the lead you worked to earn.

Jakob's Law · Laws of UX

Trust & credibility signals

Missing social proof, a broken link, a 2019 copyright year: small cracks that tell a first-time visitor nobody's home. It flags the ones that cost conversions.

Doherty Threshold · Laws of UX

Speed & feedback

Slow first paint and buttons that give no feedback on click read as "broken" long before a user blames their connection. The agent notices what a stopwatch can't describe.

Questions

How do I get my website roasted for free?

Paste your URL above and the agent runs a free mini roast of your homepage in a minute or two, returning findings with screenshots. No signup, no card. The full roast crawls every page and tests every flow.

Is this just ChatGPT looking at a screenshot?

No. ClapBack drives a real browser with Claude Opus and interacts with the live page. It scrolls, clicks, and submits forms, which is where roughly half of UX issues live. Screenshot-only tools can't see those.

Will the roast be mean?

The tone is savage; the findings are not made up. Every complaint cites a named rule and shows the screenshot. We punch at the product, never at the person who built it.

Is it safe to run on my live site?

It browses like an ordinary visitor and won't change your data. If live writes make you nervous, point it at a staging URL instead.
