Most MVPs don't fail because the product is bad. They fail because launch day arrives and nobody remembered DNS propagation takes 48 hours, the privacy policy is missing, or the Stripe webhook isn't configured for production. The difference between a smooth launch and a catastrophic one is a checklist.
This is the 47-item checklist Meld uses internally. We refined it across multiple client launches—including AeroCopilot, which went from zero to production with 173 database tables, 444 migrations, and full regulatory compliance. Every item on this list exists because someone, somewhere, forgot it and paid the price.
Print it. Pin it to the wall. Work through it methodically. Your launch will thank you.
Category 1: Infrastructure & DevOps (10 Items)
These items must be completed at least one week before launch. Infrastructure problems on launch day are unfixable under pressure.
1. Production environment is provisioned and tested. Not staging. Not "it works on my machine." A real production environment with production-grade resources.
2. Domain DNS is configured and propagated. DNS changes can take 24–48 hours. Do this early. Verify with dig or DNS checker tools.
3. SSL/TLS certificates are installed and auto-renewing. Let's Encrypt or your provider of choice. Test the renewal process before launch, not after expiry.
4. CDN is configured for static assets. Images, fonts, CSS, and JavaScript should serve from edge locations. This isn't optional for global products.
5. Database backups are automated and tested. Automated backups mean nothing if you've never tested a restore. Run a full restore drill before launch.
6. Environment variables are set for production. Every single one. API keys, database URLs, third-party service credentials. One missing variable will crash your app silently.
7. Monitoring and alerting are active. Uptime monitoring, error tracking (Sentry or equivalent), and performance monitoring. You need to know about problems before your users tell you.
8. CI/CD pipeline deploys to production reliably. Run at least three successful deployments before launch day. The pipeline should be boring.
9. Rate limiting and DDoS protection are configured. Cloudflare, AWS WAF, or equivalent. Launch announcements attract bots.
10. Rollback procedure is documented and tested. When (not if) something goes wrong, how do you revert to the last known good state? Document the exact commands.
Category 2: Application Quality (8 Items)
Ship quality. Choosing the right tech stack matters, but even the best stack won't save you from untested code.
11. All critical user paths are tested end-to-end. Sign up, onboard, perform the core action, pay. Every step. On every supported browser.
12. Authentication flows work correctly. Sign up, sign in, password reset, email verification, OAuth flows. Test each one. Test edge cases: expired tokens, duplicate emails, special characters in passwords.
13. Payment integration processes real transactions. Switch from Stripe test mode to live mode. Process a real $1 charge. Verify the webhook hits your server. Confirm the receipt email sends.
14. Email deliverability is verified. Send test emails from production. Check spam scores. Verify SPF, DKIM, and DMARC records. A product nobody receives emails from is a product nobody can use.
15. Mobile responsiveness is tested on real devices. Not just Chrome DevTools. Real phones. Real tablets. Different screen sizes. Different operating systems.
16. Error handling shows user-friendly messages. No stack traces in production. No "undefined is not a function" shown to users. Every error path should display a helpful message.
17. Loading states exist for all async operations. Every button that triggers an API call should show a loading state. Every page that fetches data should show a skeleton or spinner.
18. Performance benchmarks meet targets. Core Web Vitals: LCP under 2.5s, FID under 100ms, CLS under 0.1. Test with Lighthouse. Test on slow connections.
Category 3: Security & Compliance (9 Items)
Security isn't a feature you add later. It's a foundation you build on. Our CTO's experience building enterprise systems at Avenue Code for clients like Banco Itaú taught us that security shortcuts always cost more than doing it right.
19. Authentication uses industry-standard protocols. OAuth 2.0, OpenID Connect, or equivalent. No custom auth schemes. No storing passwords in plain text.
20. API endpoints validate and sanitize all inputs. SQL injection, XSS, and CSRF protections are non-negotiable. Use parameterized queries. Escape output.
21. HTTPS is enforced everywhere. HTTP requests redirect to HTTPS. HSTS headers are set. Mixed content warnings are eliminated.
22. Privacy policy is published and accessible. Written by someone who understands GDPR, CCPA, and LGPD (if you operate in Brazil). Linked from the footer of every page.
23. Terms of service are published. Cover liability, acceptable use, data ownership, and termination. Have a lawyer review them.
24. Cookie consent is implemented (if required). EU users need explicit consent. Don't just throw up a banner—actually respect the user's choice.
25. Data encryption at rest and in transit. Database encryption enabled. All API calls over HTTPS. Sensitive fields (SSN, payment info) encrypted at the application level.
26. Access controls are implemented and tested. Role-based access control. Admin functions inaccessible to regular users. Test by attempting unauthorized actions.
27. Security headers are configured. Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy. Test with securityheaders.com.
Category 4: Marketing & Growth (8 Items)
Your product doesn't market itself. Even the best MVP needs a strategy for user acquisition from day one.
28. Landing page is live and converting. Clear value proposition. One primary CTA. Social proof if available. Mobile-optimized.
29. Analytics tracking is implemented. Google Analytics 4, Mixpanel, PostHog, or equivalent. Track sign-ups, activation, retention, and revenue events.
30. SEO fundamentals are in place. Title tags, meta descriptions, Open Graph tags, sitemap.xml, robots.txt. Structure your content for search engines from day one. When we launched AeroCopilot, our co-founder's 25 years of SEO expertise—honed building WebTraffic and earning TopSEOs #1 PPC Agency in Brazil for three consecutive years—helped us grow to 4,400 indexed pages rapidly.
31. Social media profiles are created. Claim your handles on relevant platforms. Consistent branding. Bio links point to your product.
32. Email capture is working. Newsletter sign-up, waitlist, or onboarding emails. Your email list is the only channel you own.
33. Launch announcement is drafted. Blog post, Product Hunt listing, social media posts, email to your waitlist. Have everything written and scheduled before launch day.
34. Support channel is operational. Email, chat widget, or help desk. Users will have questions on day one. Someone needs to answer them within hours, not days.
35. Referral or sharing mechanism exists. Even a simple "Share with a friend" link. Communities like Indie Hackers are great places to share your launch and get early traction. Word of mouth is your cheapest acquisition channel.
Category 5: Legal & Business (6 Items)
36. Business entity is registered. LLC, C-Corp, or equivalent. Don't operate a commercial product under a personal name.
37. Business bank account is open. Separate business finances from personal finances from day one. This matters for tax time and for investor due diligence.
38. Accounting system is set up. QuickBooks, Xero, or equivalent. Track every transaction from the first dollar.
39. Contracts with co-founders are signed. Equity splits, vesting schedules, IP assignment, roles and responsibilities. The conversation is uncomfortable now; the lawsuit is worse later.
40. Intellectual property is protected. Trademark your name if budget allows. Ensure your codebase has proper licensing. Document that all code is original or properly licensed. At Meld, full code ownership is something we guarantee every client.
41. Insurance is evaluated. General liability, professional liability (E&O), and cyber liability insurance. The cost is minimal compared to the risk.
Category 6: Operations & Post-Launch (6 Items)
Launch is the beginning, not the end. The eight-week process from idea to revenue continues well past day one.
42. On-call rotation is established. Someone is responsible for production issues 24/7 for the first two weeks. Define escalation procedures.
43. User feedback collection is active. In-app feedback widget, post-onboarding survey, or scheduled user interviews. Capture feedback while the experience is fresh.
44. Key metrics dashboard is built. Daily active users, sign-up conversion rate, churn rate, revenue. Check it every morning.
45. Bug triage process is defined. How do bugs get reported, prioritized, and fixed? Define severity levels and response time targets.
46. Iteration roadmap exists. Based on user feedback and metrics, what are the next three features you'll build? Don't guess—let data drive decisions.
47. Post-launch retrospective is scheduled. One week after launch, gather the team. What went well? What went wrong? What will you change for the next launch?
How Meld Used This Checklist
When we deployed AeroCopilot to production, every one of these 47 items was checked. The result: zero downtime on launch day, immediate organic traffic from SEO preparation, and a production system stable enough to earn the trust of pilots who depend on it for flight safety.
The checklist isn't glamorous. It won't make a good Twitter thread. But it's the difference between a launch that builds momentum and a launch that destroys confidence.
Aviation software demands zero tolerance for error—and that discipline applies to launch operations, not just code quality. The same rigor that ensures 100% fuel calculation compliance ensures a smooth go-live.
Start Using It Today
Copy this checklist into your project management tool. Assign owners to each item. Set deadlines. Start working through it at least two weeks before your target launch date.
If you need help executing any of these items—or building the MVP itself—Meld specializes in AI-native development that moves at startup speed without cutting corners.
Your launch day should be exciting, not terrifying. A checklist makes the difference.
