v0 makes it pretty. We make it production-ready, for $1.
v0 is a UI generator. SEO meta, OG cards, security headers, accessibility wiring and content-quality checks aren't in scope for v0 — they are for us.
v0 generates components. Production needs more than components.
v0 is brilliant at turning a prompt into a beautifully styled section. It doesn't write your <head>, doesn't generate OG images, doesn't audit headers, and won't flag that the contrast on your hero text fails WCAG AA. We do all of that.
The 8 issues we keep finding on v0-built sites
Each one is real, severity-ranked, and ships with a one-line fix suggestion in the report.
Inherited Next.js default <title>
v0 components rarely include a Metadata export. Every route inherits ‘Create Next App’ or whatever you forgot to overwrite in the root layout.
No og:image — Vercel falls back to a screenshot
Without an explicit og:image route or static asset, your Slack/X/LinkedIn previews look generic and untrustworthy.
Decorative icons announced to screen readers
v0 emits Lucide icons without aria-hidden, so a screen reader reads ‘Sparkles button Sparkles arrow-right’ before the actual label.
Insufficient contrast on shadcn ‘muted’ text
v0 leans on text-muted-foreground for body copy. On the default Tailwind palette this drops below WCAG AA on light backgrounds.
No CSP on the Vercel deployment
Vercel's defaults are decent but you still need a CSP if you embed third-party scripts. We grade your headers and tell you the exact rule to add.
Every component marked ‘use client’
v0 defaults to client components even when the section is static. Hurts FCP, hurts crawlability, and breaks streaming SSR.
Mobile breakpoint not tested at 375px
v0 previews at desktop. On a real iPhone SE viewport, primary CTAs frequently end up below the fold.
Placeholder copy not replaced
‘Acme Inc.’, ‘Lorem ipsum’ and ‘john@example.com’ ship to production more often than you'd think.
v0 pre-launch checklist
Check these before you share your link. The full PageLens audit catches everything else.
- Replace the 'Create Next App' <title> in your root layout metadata
- Add an og:image route or static OG asset
- Add <meta name="description"> to every page's metadata export
- Add aria-hidden="true" to decorative Lucide icons
- Check contrast ratios on text-muted-foreground elements
- Move purely static sections from 'use client' to server components
- Verify mobile layout at 375px — check CTA visibility above the fold
- Replace any placeholder copy ('Acme Inc.', 'john@example.com')
- Add Content-Security-Policy via next.config headers
- Test with a screen reader (VoiceOver/NVDA) for announcement order
This covers the basics. A full PageLens scan checks hundreds of rules across 10 categories — including the ones that are hard to spot manually.

Questions v0 users ask us
I use v0 as a starting point, then customise heavily. Will the report still be relevant?
More relevant, not less. We scan your live site — whatever you've shipped. Heavy customisation usually introduces new issues v0 wouldn't have generated.
v0 generates Next.js. Do you handle App Router and React Server Components?
Yes — we use a real Chromium browser, so the page is fully rendered (RSC, streaming, suspense) before we capture HTML and screenshots.
