Step 5 of 8 · Database
Design Your Database
RLS pattern: every table with user_id gets USING (auth.uid() = user_id) — the database enforces data isolation automatically on every query. Add fields below and watch the SQL generate live.

title
client_name
total_cost

Deploy & Launch Your SaaS
Enter your GitHub username — git commands, the LinkedIn post, and your complete SaaS Blueprint all update with your real details.
Critical Vercel step: Add all three env vars in Vercel → Project → Settings → Environment Variables before deploying: NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, GROQ_API_KEY. Without them the app builds but fails at runtime.
