Beyond Quick Prototypes. Production-Grade Prompts.

Build a SaaS analytics dashboard with charts, user management, and a settings page. Use React and Tailwind.

You are a senior full-stack engineer building production SaaS applications.

Create an analytics dashboard with:
- Framework: [Next.js App Router / Remix / Vite + React]
- Styling: [Tailwind CSS / CSS Modules]
- Auth: [Auth.js / Clerk / Supabase Auth]

Requirements:
1. Dashboard layout with sidebar nav and responsive grid
2. Charts using [Recharts / Chart.js] with loading skeletons
3. Data fetching with React Query — stale-while-revalidate
4. Role-based access: admin sees all, member sees own data
5. Error boundaries around each widget (one crash does not break the page)
6. Optimistic UI updates for settings mutations
7. Accessibility: keyboard nav, ARIA labels, focus management

Performance targets: LCP < 1.5s, no layout shift on data load.

Add user authentication with login, signup, and password reset. Use email and password.

You are a backend security engineer implementing production authentication.

Build an auth system for: [Next.js / Express / Fastify]
- Database: [PostgreSQL / MySQL] via [Prisma / Drizzle]
- Session strategy: [JWT + httpOnly cookies / server sessions]

Generate:
1. Signup with Zod validation (email format, password: 8+ chars, uppercase, number)
2. Password hashing with bcrypt (12 rounds) — never store plaintext
3. Login with rate limiting (5 attempts per IP per 15 min)
4. Password reset flow: time-limited token (1h), single-use, emailed link
5. CSRF protection on all mutation endpoints
6. Session refresh logic — silent token rotation before expiry
7. Account lockout after 10 failed attempts with admin unlock

Security: timing-safe comparisons, no user enumeration on login/reset, sanitized logs.

Deploy this app to production with a database and environment variables.

You are a DevOps engineer preparing a production deployment.

Deploy: [Next.js / Node.js / Python] application
- Host: [Vercel / AWS / Railway / Fly.io]
- Database: [PostgreSQL on Supabase / RDS / Neon]
- CI/CD: [GitHub Actions / GitLab CI]

Generate:
1. Dockerfile with multi-stage build (builder + runner, minimal final image)
2. GitHub Actions workflow: lint, typecheck, test, build, deploy
3. Environment variable management: .env.example with every required var
4. Database migration strategy: up + down scripts, zero-downtime deploys
5. Health check endpoint: /api/health returning DB connectivity + uptime
6. Monitoring: structured logging, error tracking integration point
7. Rollback plan: one-command revert to previous deployment

Include: rate limiting config, CORS policy, and security headers (CSP, HSTS, X-Frame-Options).
