Half your buttons don't work.
You built it with AI, and it looks finished. But does it actually work? We send an AI to your live app to try the one thing it's for, the way a visitor would, then show you exactly where it breaks: dead buttons, blank screens, flows that never finish.
What we actually check
Not a checklist run against your HTML. We load your app in a real browser and verify the outcome a visitor gets, the things that are broken most often in fast-built apps. You get a score, the single worst issue free, and the full breakdown behind a free account.
- The main job completes: an AI actually attempts your core flow, sign up, book, buy, generate, and tells you if a real visitor could finish it.
- It renders: catches the blank white screen an app shows when its JavaScript crashes on load.
- The buttons work: finds the dead buttons and placeholder links that look real but do nothing when clicked.
- The backend answers: flags your app's own API calls that fail, the frontend shipped but the thing behind it is broken.
- Nothing 404s: every link and image resolves, and your main call to action goes somewhere real.
- Mobile holds up: checks the layout does not overflow on a phone, where most of your visitors are.
How it works. A real browser, not a guess.
We open your app the way a visitor does, walk the path they take, and show you the exact step where it breaks.
We load your live app
In a real browser, running your actual JavaScript, so we see what a visitor sees, not the empty shell a simple checker reads.
We walk the flow
We find your main call to action and check the journey a visitor takes, watching for errors, dead controls and failing requests along the way.
We score it and hand you the fixes
A 0 to 100 score, the exact broken things with the evidence, and a copy-paste fix for each you can drop straight into your AI builder.
Free score, about twenty seconds, no card.
Or check every page
One page is the fast answer. Checking the whole site is the real one: we find your pages, open each in a real browser, and send the AI through your main flows, so you see what a visitor could hit anywhere, not just on the one URL you happened to paste. That one needs the free account. The single-page check stays free and anonymous.
- Up to 20 pages: found from your sitemap, or crawled for if you do not have one. If your site is bigger, the report says exactly which pages we did not reach.
- Up to 3 main flows: the AI drives the pages most likely to carry a real journey, sign up, contact, book, checkout.
- Close the tab: it runs as a background job for a few minutes, so you can walk away and pick it up later from your recent checks.
- Every issue under its page: a finding is no use without its address, so each one is listed on the exact page it is on.
- One score for the site: a repeated problem counts once at full weight and less each time after, so one template bug cannot drown out a broken checkout.
Rather have it fixed for you?
The report hands you a fix for every issue, that's the DIY route. If you'd sooner not touch it, I'll do it: wire up the dead buttons, fix the failing requests, sort the mobile layout, and hand you back a clean re-check.
A done-for-you fix, scoped to your app, from £249. Tell me what the check found and I'll reply with a fixed price.
Shipping fast is great. Shipping broken is not.
The speed of AI-built software has a shadow: the same tools that build an interface in minutes will happily leave a button wired to nothing, a form that submits nowhere, or an API key that works on your machine and not in production. It looks finished. It passes your own quick click-through, because you click the happy path you built. Then your first real visitor clicks the part you never tested, and it silently fails. The gap between "it looks done" and "it works for a stranger" is exactly what this checks.

Who's behind it
I'm Josh Snoddy. I build real software live with Claude, and I've shipped the exact broken buttons this tool catches, so I built the tool to catch them. It loads your app the way a visitor would, tells you plainly what breaks, and hands you the fix for each.
I run it on my own apps before I put it in front of yours. It uses obviously fake test data and stops before anything that pays or deletes. It tries, it reports, and it shows its working.
Questions people ask.
It loads your live page in a real browser and watches what happens: does the app render or show a blank screen, does it throw a JavaScript error, do its own API calls fail, are its buttons and links actually wired to something, do the links resolve, and does the layout break on mobile. It reports the specific things that break, with the evidence.
A link checker reads your static HTML and checks whether URLs return 200. For an app built with tools like Lovable, v0 or Bolt, the static HTML is nearly empty: the app only exists after its JavaScript runs. This checker runs that JavaScript in a real browser, so it sees the actual app a visitor sees, including a blank screen, a dead button or a failing request that a link checker is blind to.
Yes. It loads your page in a real browser and, if you choose a walkthrough, attempts your main flow the way a visitor would, using obviously fake test data. It never pays, deletes anything, enters card details, or takes any irreversible action: it stops at those points and reports instead. If your site has a contact form, the check may submit one clearly labelled test message. You confirm you own or have permission to test the site before every check.
Yes, with the free account. A whole-site check finds your pages from your sitemap, or crawls for them if you do not have one, opens up to 20 of them in a real browser, and sends the AI through up to 3 of your main flows. It runs as a background job for a few minutes, so you can close the tab and pick the result up later from your recent checks. You get one score for the site, with every issue listed under the exact page it is on. If your site has more than 20 pages, the report says exactly which ones we did not reach. The single-page check stays free and needs no account.
AI coding tools generate a convincing interface fast, but often leave the wiring incomplete: a button with no action, a form that submits nowhere, an API key or endpoint that works on your machine but not in production. It looks finished and passes your quick click-through, then the first real visitor hits the part you did not test. This finds those before they do.
The score and your single worst issue are free, no card. The full report, with every broken thing, the exact evidence, the journey a visitor takes and a copy-paste fix for each, unlocks with a free account (a one-click email login). No password, no payment.
Every finding comes with a paste-ready fix you can hand to your AI builder, plus one consolidated brief covering them all. Fix what it finds, then re-check. Or have it fixed for you.
