v0 vs Lovable: Security Responsibilities
Updated 2026-10-17
v0 is primarily a UI and Next.js code generator; Lovable produces a hosted app wired to Supabase. The security checklist follows the architecture. This comparison describes common default patterns and where security responsibility sits. Platforms change quickly; verify current behaviour in each vendor's documentation.
| Area | v0 (typical) | Lovable (typical) |
|---|---|---|
| Output | React/Next.js components & apps | Hosted Vite/React app + Supabase |
| Secrets | Next.js server env (avoid NEXT_PUBLIC_) | Supabase Edge Function secrets |
| Headers | next.config / vercel.json | Hosting / custom domain config |
| Data access | Your route handlers & DB | Supabase RLS |
Bottom line
With v0, check server/client boundaries and headers in your Next.js app. With Lovable, check RLS, storage and Edge Functions.
