How to secure a Lovable app before launch

Lovable can take you from prompt to working product in an afternoon. Before you share the link, spend one more hour on this sequence — it covers the gaps that appear in almost every generated app.

Step 1 — Lock down Supabase RLS (15 min)

Lovable apps run on Supabase, and missing Row-Level Security is the single most common breach cause in vibe-coded apps. In your Supabase dashboard, open Authentication → Policies and confirm every table shows RLS enabled with a policy scoping rows to auth.uid(). A table without policies is readable by anyone holding your public key — which is everyone, because the public key ships in your frontend.

Step 2 — Hunt for exposed keys (10 min)

Search your project for sk_live, sk-, and service_role. Any hit in frontend code is critical: move it to Lovable's environment settings and rotate the key at the provider, because the old value may already be scraped.

Step 3 — Test as a stranger (10 min)

Open your published app in a private window, logged out. Try visiting account pages directly by URL. Try calling an edge function with no session. If anything private renders or responds, your auth is client-side-only and needs a server-side check.

Step 4 — Check the edge functions (10 min)

Every function that writes data should verify the caller's identity first, and validate inputs before using them in queries. AI-generated functions frequently skip both to "keep it simple."

Step 5 — Run a scan and keep the report (5 min)

Paste the generated code into VibeSafe (or connect the GitHub sync). You'll get a 0–100 safety score, each issue explained in plain English, and a PDF report you can keep as your pre-launch record. Fix the criticals, re-scan, ship.
