Your Lovable app is probably shipping with 8+ issues. Find them for $1.
Lovable nails the look. It does not nail SEO, accessibility, security headers, or social previews. We scan every page and tell you exactly what to fix.
Every Lovable launch we've scanned has the same gaps
Lovable's generated React + Supabase apps look great in the preview pane. Then you ship them and discover the favicon is still the Vite logo, the OG card is broken on every share, and Google can't read half your routes. We catch all of that in one $1 scan.
The 11 issues we keep finding on Lovable apps
Each one is real, severity-ranked, and ships with a one-line fix suggestion in the report.
Supabase service-role key in client bundle
Lovable sometimes leaks the service-role key (not the anon key) into the React bundle. Anyone hitting your site can DevTools it out and bypass RLS entirely.
Default Vite browser title
We see ‘Vite + React’ as the <title> on roughly 40% of shipped Lovable apps. Google ranks you on that string. Users see it in their tab.
No og:image on any page
Every share to LinkedIn, Slack, X or iMessage renders a broken thumbnail. Single biggest source of ‘this looks unprofessional’ feedback for vibe-coded launches.
Default Vite/Lovable favicon
Showing the Vite lightning bolt or the Lovable heart in browser tabs telegraphs ‘weekend project’ to anyone who recognises them.
Form inputs missing labels
Tailwind/shadcn inputs Lovable generates often skip <label> wiring. Screen-reader users (and Google) can't tell what an input is for.
No Content-Security-Policy
A single XSS through a third-party script (analytics, chat, embed) can hijack every Supabase auth token in the page.
Hero image loaded at full size
Lovable doesn't auto-optimise uploaded images. We routinely find 2–4 MB hero PNGs delaying LCP by 1.5–2.5 seconds on 4G.
No <meta description>
Google falls back to scraping random body copy for the SERP snippet. Click-through tanks because the snippet reads like a fortune cookie.
404 route returns blank white page
Lovable's default React Router setup doesn't include a custom 404. Visitors who guess a wrong URL see a void and leave.
No sitemap.xml — pages are invisible to crawlers
Lovable doesn't generate a sitemap.xml. Google can't discover your /pricing or /docs pages unless another site links to them.
Session cookie missing HttpOnly flag
Supabase auth cookies set without HttpOnly are readable by any XSS payload — one injected script steals every session.
Lovable pre-launch checklist
Check these before you share your link. The full PageLens audit catches everything else.
- Replace the default Vite/Lovable <title> with your product name
- Add a custom favicon (not the Vite lightning bolt or Lovable heart)
- Set og:image, og:title and og:description on every public page
- Add a <meta name="description"> to the homepage
- Check that Supabase service-role keys are NOT in the client bundle
- Add Content-Security-Policy headers
- Add aria-labels to all icon-only buttons
- Ensure every <img> has meaningful alt text
- Add a custom 404 page (React Router catch-all)
- Optimise hero images to under 200KB (use WebP or AVIF)
- Generate a sitemap.xml (vite-plugin-sitemap or manual)
- Add SPF and DMARC DNS records for your custom domain
- Add a /llms.txt file so AI search engines can find your app
- Add a cookie consent banner if you use analytics (GDPR requirement)
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 Lovable users ask us
Will this break my Lovable app?
No. We never log in, modify, or write to your site — we crawl publicly accessible pages exactly like a Googlebot would, capture screenshots, and read the rendered HTML. Read-only end-to-end.
I deployed through Lovable's Publish — does the audit work?
Yes. Whether you published to a *.lovable.app subdomain or pointed a custom domain at your own Vercel/Netlify deployment, we scan whatever URL you give us.
Can the AI suggest specific fixes I can paste back into Lovable?
Each finding includes a concrete remediation suggestion you can paste into the Lovable chat box (e.g. ‘update <head> with og:image referencing /preview.png’). Most fix in one prompt.
