Why Best Practices Matter
The difference between a vibe coded app that feels professional and one that feels broken often comes down to how you interact with the AI. These 15 rules are distilled from thousands of successful vibe coding projects.
Prompting Rules
1. Be specific about the stack
Bad: "Build me a todo app."
Good: "Build a task management app with Next.js 14, TypeScript, Tailwind CSS, and Supabase. Include user authentication, a Kanban board with drag-and-drop, and mobile-responsive design."
The more context you provide upfront, the better the AI's first output will be.
2. Describe the user, not just the feature
Bad: "Add a dashboard."
Good: "Add a dashboard for SaaS admins who need to see monthly revenue, active users, churn rate, and recent signups at a glance. Use Recharts for visualizations."
Understanding the end user helps the AI make better UX decisions.
3. One thing at a time
- Don't ask for 10 features in one prompt. Build incrementally:
- First: "Create the project structure with authentication"
- Then: "Add a dashboard with KPI cards"
- Then: "Add a settings page"
- Then: "Integrate Stripe billing"
Each step builds on the last, and you can catch issues early.
4. Reference existing designs
"Design inspired by Linear" or "UI similar to Notion" gives the AI a strong visual reference. Name specific products, not abstract adjectives like "modern" or "clean."
5. Include edge cases in your prompt
"Handle the case where the user has no data yet — show an empty state with an illustration and a CTA to create their first item."
AI tends to build the happy path. You need to explicitly request error states, empty states, and loading states.
Architecture Rules
6. Start with authentication
If your app has user accounts, set up auth first. Everything else (database schemas, page layouts, API routes) depends on knowing who the user is.
7. Use established patterns
Ask for "Next.js App Router with server components" not custom routing. Ask for "Supabase Row Level Security" not custom auth middleware. The AI produces better code when using well-documented patterns.
8. Keep the database schema simple
Start with 3–5 tables maximum. You can always add more later. Complex schemas with 15+ tables are hard for AI to manage correctly.
9. Don't fight the framework
If you're using Lovable, work with its Supabase-first approach. If you're using v0, embrace shadcn/ui. Fighting the tool's defaults wastes time and produces worse results.
Quality Rules
10. Review every file the AI creates
- Even if you can't write code, you can read it. Look for:
- Hardcoded values that should be variables
- Console.log statements left in production code
- API keys or secrets in frontend code
- TODO comments that indicate incomplete work
11. Test on mobile before shipping
Over 50% of web traffic is mobile. Always test your app on a phone (or Chrome DevTools mobile view) before showing it to anyone.
12. Add proper error handling
Ask the AI: "Add error boundaries, loading states, and user-friendly error messages to all pages." Default AI output often shows raw error messages or blank screens on failure.
13. Set up version control immediately
Create a Git repository and commit after every significant change. This lets you undo mistakes and track progress. If using Lovable or Bolt, push to GitHub regularly.
Shipping Rules
14. Deploy early, iterate in production
Don't wait until it's "perfect." Deploy your app after the core feature works. Real user feedback is more valuable than another week of prompting.
15. Ship, then optimize
Performance, SEO, analytics — add these after your app is live and people are using it. Premature optimization is the enemy of shipping.
The Meta-Rule
The best vibe coders are clear thinkers, not technical experts. If you can write a clear brief for a freelancer, you can write effective prompts for an AI. The skill is knowing what you want, not knowing how to build it.
