The MVP Launch Checklist: 30 Things to Do Before Going Live (2026 Edition)

The Complete MVP Launch Checklist for 2026

You've built your MVP. The features work, the design looks good, and you're itching to share it with the world. But before you flip the switch, there are critical items that can make or break your launch.

The research is sobering: only 34% of organizations deliver projects on time (Wellingtone 2024), and 47% lack access to real-time KPIs during launches. Most launch failures aren't technical — they're process failures. Forgotten legal requirements, missing monitoring, broken payment flows, slow load times that tank conversion.

Here's the complete MVP launch checklist — 30 items across technical, security, marketing, legal, and operations categories. Not all will apply to every product, but reviewing each one will prevent the "oh no, we forgot about that" moments.

Technical: Items 1–12

Security (Non-Negotiable)

The 2026 landscape is unforgiving. AI-generated code frequently contains security vulnerabilities — SQL injection, authentication bypasses, data exposure. These checks are mandatory.

• 1. SSL certificate installed — Your site must load over HTTPS. No exceptions. Verify in the browser (padlock icon) and test http:// redirects to https://.

• 2. Authentication tested end-to-end — Login, logout, password reset, email verification, session expiry, concurrent sessions. Test on multiple browsers.

• 3. Input validation server-side — All user inputs validated on the server, not just client-side. Client-side validation is UX; server-side is security.

• 4. Environment variables secured — No API keys, passwords, database credentials, or secrets in your codebase or Git history. Run git log -p | grep -i 'api_key\|password\|secret' to verify.

• 5. CORS configured correctly — Only your domain(s) can access your API. Check headers with browser DevTools Network tab.

• 6. SQL injection / XSS protected — Use parameterized queries (never string concatenation). Sanitize HTML output. Test with OWASP ZAP or similar scanner.

Performance

Every second of load time reduces conversion. Target sub-3-second fully interactive.

• 7. Page load under 3 seconds — Run Lighthouse on core pages. Fix anything below 90 performance score. Mobile is especially critical.

• 8. Images optimized — Use Next.js Image component, WebP format, lazy loading. Images are the #1 cause of slow pages.

• 9. Mobile responsive and tested on real devices — Browser DevTools aren't enough. Test on actual iOS and Android devices. Touch targets should be minimum 44×44px (48×48px recommended).

• 10. Core Web Vitals passing — LCP < 2.5s, FID < 100ms, CLS < 0.1. Check in Google Search Console or PageSpeed Insights.

Infrastructure

• 11. Production environment separate from development — Different database, different API keys, different error verbosity.

• 12. Database backups configured and tested — Automated daily backups. Test the restore process before launch — a backup you can't restore is worthless.

Security Deep-Dive: Items 13–18

AI-generated code (from Bolt, Lovable, Cursor, or similar) needs extra scrutiny. These checks specifically target common AI-generated vulnerabilities.

• 13. Row-level security (RLS) enabled — Users can only see their own data. Verify at the database level, not just application code.

• 14. API rate limiting configured — Prevent brute force attacks and API abuse. 100 requests/minute per IP is a reasonable starting point.

• 15. Session management secure — Secure, httpOnly cookies. Automatic logout after inactivity (30 minutes typical). Session tokens regenerated on login.

• 16. Error messages don't leak information — Production errors should be user-friendly, not stack traces. Log details server-side; show "Something went wrong" client-side.

• 17. Dependency audit passed — Run npm audit or pnpm audit. Fix critical and high vulnerabilities before launch.

• 18. Security headers configured — Content-Security-Policy, X-Frame-Options, X-Content-Type-Options. Use securityheaders.com to verify.

Monitoring and Observability: Items 19–22

47% of organizations lack real-time KPIs (Wellingtone 2024). Don't be one of them.

• 19. Error monitoring active — Sentry, LogRocket, or similar. You need to know when production breaks before users tell you.

• 20. Uptime monitoring configured — Better Uptime, Pingdom, or similar. Get SMS/Slack alerts when the site goes down.

• 21. Application analytics installed — Vercel Analytics, Mixpanel, PostHog, or Google Analytics. Track sign-ups, conversions, and key actions.

• 22. Structured logging in place — JSON logs with request IDs for tracing. You'll need this to debug production issues.

Marketing and SEO: Items 23–26

• 23. Meta tags on every page — Title (under 60 chars), description (under 155 chars), OG image (1200×630px recommended). Use the Open Graph Debugger and Twitter Card Validator.

• 24. Sitemap generated and submitted — Create sitemap.xml, submit to Google Search Console. For Next.js, use the built-in sitemap generation.

• 25. robots.txt configured — Allow search engines to crawl public pages, block admin and private routes.

• 26. UTM parameters ready for launch campaigns — Prepare tracking links before you announce. You won't be able to retroactively add attribution.

Legal: Items 27–29

• 27. Privacy Policy published — Required by law in most jurisdictions. Cover what data you collect, how you use it, how users can request deletion. GDPR requires specific disclosures for EU users.

• 28. Terms of Service published — Define acceptable use, liability limits, dispute resolution, account termination rights.

• 29. Cookie consent banner (if applicable) — Required in the EU (GDPR), increasingly elsewhere. Don't set non-essential cookies until consent is given.

Operations: Item 30

• 30. Payment flow tested with real money — Make real purchases (and refunds) with live payment credentials. Test mode isn't enough. Verify webhook handling, receipt emails, subscription renewals.

The Launch Day Checklist

Morning Before Launch

1. Final checklist review — Walk through all 30 items one more time
2. Complete user flow test in production — Sign up, complete core action, make payment
3. Payment verification — Make a real purchase, verify receipt, process refund
4. Team notifications — Confirm everyone knows the launch time and their role
5. Monitoring dashboards open — Have error tracking, analytics, and uptime monitoring visible

Launch

1. Remove access restrictions — Disable password protection, update DNS if needed
2. Send launch announcement — Email list, existing users, stakeholders
3. Post on social media — Coordinated across channels with UTM tracking
4. Submit to communities — Product Hunt, Hacker News, relevant subreddits
5. Monitor error tracking — Watch for spikes in the first hour

First 48 Hours

1. Error monitoring: watch continuously — The first 48 hours surface most production bugs
2. Support response: under 2 hours — Speed builds trust with early users
3. Track key metrics — Sign-up rate, activation rate, payment conversion
4. Collect user feedback — What confuses people? What do they ask for?
5. Ship critical fixes immediately — Log everything else for the next sprint

What to Do When Things Go Wrong

They will. Something will break on launch day. Here's the emergency playbook:

The cardinal rule: Communicate before users complain. "We're aware of an issue and working on it" is infinitely better than silence.

The 2026 Prototype-to-Production Path

In 2026, many MVPs start as prototypes in Bolt, Lovable, or v0. The launch checklist applies regardless of origin — but prototype-built apps need extra attention on:

• Security items 13–18 — AI-generated code often has security gaps
• Performance items 7–10 — Prototypes optimize for speed of creation, not runtime performance
• Infrastructure items 11–12 — Prototypes often use development-tier databases

The Production Lift (€3,500, 1 week) specifically addresses these gaps: taking a validated prototype to production-ready with proper auth, database, error handling, and security.

What Changes from Prototype to Production

After Launch: The First 30 Days

Launch isn't the finish line — it's the starting line.

Week 1: Fix and Learn

• Fix every critical bug immediately
• Respond to every piece of user feedback
• Identify the biggest drop-off points in your funnel
• Track: sign-up rate, activation rate, Day-1 retention

Week 2: Analyze and Prioritize

• Analyze user behavior data (where do people get stuck?)
• Categorize feedback into themes
• Prioritize the top 3 improvements based on impact
• Track: feature usage, support ticket themes, NPS if applicable

Weeks 3–4: Ship Improvements

• Deploy the top 3 improvements
• A/B test if traffic allows
• Continue feedback collection
• Start planning v1.1 based on patterns

The research says: Organizations that prioritize soft skills (communication, responsiveness, iteration) see 72% project success rates vs 65% for those that don't (PMI 2023). The first 30 days after launch are when those soft skills matter most.

The Bottom Line

Most launch failures aren't technical. They're process failures — forgotten security checks, missing monitoring, broken payment flows, legal gaps.

This checklist exists because only 34% of projects launch on time and 44% of workers have experienced multiple abandoned projects. The difference between successful launches and failures often comes down to preparation.

The 30 items here represent accumulated lessons from dozens of MVP launches. Not all will apply to every product, but reviewing each one takes less time than fixing a production incident.
