v0 SEO & security audit before you deploy on Vercel.
Beautiful components don't mean launch-ready. Free v0 audit for metadata, performance, accessibility, and the production details v0 doesn't generate by default.
Supabase backend testing (optional)
Provide Supabase credentials to run deeper RLS and cross-tenant isolation probes. Secrets are encrypted at rest and never appear in scan reports.
Expand to add optional Supabase credentials.
What v0 builds often skip
- •shadcn pages missing page-level metadata exports
- •Images unoptimized — killing LCP on marketing hero
- •Dark mode contrast failures on muted text
- •Structured data missing for SaaS landing pages
- •Vercel preview URL indexed instead of production domain
- •Analytics and cookie consent not wired

Launch gate, not another SEO suite
