Why v0.dev apps benefit from a senior-engineer audit
v0 produces gorgeous UI from a prompt. But UI without conversion logic, without accessibility, without error states, without proper form validation, is just a screenshot in code form. We routinely audit v0-built apps that look like a designer crafted them but break on a screen reader, fail the keyboard-only navigation test, and silently drop form submissions. The cure is fast: a one-shot audit that returns copy-paste fixes you can hand to Cursor or Claude.
Top issues we find in v0.dev apps
Generic-but-true patterns from our audit pipeline. The audit flags these on YOUR specific project with file-and-line citations.
Buttons aren't actually buttons (clickable divs everywhere)
v0 frequently styles `<div onClick>` as if it were a button. Screen readers can't activate them, keyboard users can't tab to them, and Google Lighthouse penalizes them.
Fix: Replace every clickable div with <button type="button"> or <a href> as appropriate. Add proper focus-visible styling.
Form submits without preventDefault → page reload kills state
v0's generated forms sometimes omit e.preventDefault() in the handler. The user clicks submit, the page reloads, all client state vanishes, and they're back to the homepage thinking the form is broken.
Fix: Add e.preventDefault() as the first line of every form onSubmit handler. Verify by submitting and confirming no page reload.
No loading states on async actions
Click submit, nothing visibly happens for 4 seconds, user clicks 5 more times, now you have 6 duplicate submissions. v0's default is no loading indicator.
Fix: Add a useState boolean for isLoading. Disable the submit button and swap text to a spinner when isLoading is true. Reset on success or error.
Color-only conveyance fails contrast and color-blindness checks
v0 likes muted color palettes. The result: red error text on a light background that fails WCAG AA contrast, and "success green" that's indistinguishable from "info gray" for the 8% of users with color blindness.
Fix: Run a contrast checker on every state. Always pair color with an icon or text label (✓ Success / ✗ Error).
No mobile breakpoint testing — looks great at 1440 only
v0's preview defaults to desktop. Designs that scale linearly on mobile typically have text-truncation issues, off-screen CTAs, and form fields that zoom on focus (iOS).
Fix: Add explicit Tailwind breakpoint variants (sm:, md:) on every component. Test in mobile emulation; set input font-size to 16px+ to avoid iOS zoom.
Static placeholder content shipped to production
v0 generates with placeholder text (Lorem ipsum, fake testimonials, '<Company Name>'). We routinely audit live v0 apps that still show these.
Fix: Grep the codebase for 'lorem', 'ipsum', 'placeholder', 'TODO'. Replace every instance with real copy before shipping.
Example fix prompts you'll get
Every finding ships with a paste-ready prompt for Cursor or Claude. Here are three examples we'd typically hand back for a v0.dev project.
In every .tsx file under components/, find <div onClick={...}> and replace with <button type="button" onClick={...} className="..."> preserving styling. Add focus-visible:ring-2 focus-visible:ring-orange-500 to the className.
For every form in the app, ensure the onSubmit handler starts with `e.preventDefault();` and that the submit button is disabled when an isSubmitting state is true. Show a Loader2 icon during submission.
Find every component that shows colored status indicators (success, error, warning). Pair the color with a lucide-react icon (Check, X, AlertTriangle) so the meaning is conveyed without color.
