Checklist Before Launching an App
Before launching, verify product sign-off, legal compliance, infrastructure stability, customer support readiness, marketing preparation, and success metrics. This checklist covers everything from code to marketing so nothing falls through the cracks.
Why this matters
A structured pre-launch checklist turns an overwhelming milestone into manageable steps. Without one, teams waste hours on manual follow-up trying to figure out what is done and what is missing — a clear checklist eliminates that guesswork.
What's at stake
Launching without preparation leads to preventable failures — broken payment flows, missing legal pages, no support channel, and zero visibility into what users are doing. Each gap costs more to fix after launch than before.
Your checklist.
Product sign-off: all critical features work and are locked
CriticalConfirm your core features are complete and tested. Lock the feature set — no last-minute additions. Verify there are no launch-blocking bugs and that all key user flows (signup, core action, payment) work end-to-end.
Legal pages are in place (privacy policy, terms of service)
CriticalYou need a privacy policy and terms of service before accepting user data. If handling payments, add a refund policy. Services like Termly or Iubenda can generate compliant policies. Verify data protection compliance for your region.
Payment and billing flow is tested end-to-end
CriticalIf you charge users, test the complete payment flow in test mode: subscription creation, successful payment, failed payment, cancellation, and refund. Stripe test mode and Lemon Squeezy sandbox let you verify without real charges.
Infrastructure and hosting are production-configured
CriticalVerify your hosting platform is configured for production (not development mode). Check that HTTPS is enabled, environment variables are set, and your database has connection pooling if needed. Test that your app handles concurrent users.
Error monitoring and crash reporting are active
ImportantSet up Sentry, Firebase Crashlytics, or equivalent before launch. You need to know when things break before users report them. Configure alerts for critical errors so you can respond within minutes.
Customer support channel is ready
ImportantSet up at least one support channel — email, chat widget, or help center. Define response time expectations. Prepare answers for the most common questions: account issues, billing, and how-to guides.
Analytics and success metrics are tracking
ImportantDefine your launch KPIs (signups, activation rate, Day 1 retention) and verify events are tracking correctly. Manually test key flows and confirm they appear in your analytics dashboard. Without data, you are flying blind.
Marketing channels and launch messaging are prepared
ImportantFinalize your launch channels (Product Hunt, social media, email list, communities). Schedule campaigns in advance. Prepare press or partner outreach. A great product with no launch plan gets zero users on day one.
Rollback plan exists in case of critical issues
ImportantKnow how to revert to a working version if something breaks. Whether it is a previous deployment on Vercel, a git revert, or a database backup — have a tested recovery plan before you need one.
Post-launch follow-up plan is defined
RecommendedPlan your first week activities: daily monitoring schedule, feedback collection process, criteria for shipping a v1.0.1 hotfix, and a timeline for your first major update based on user feedback.
App has been tested on multiple devices and browsers
RecommendedTest on at least Chrome, Safari, and one mobile device. Check responsive layouts, touch interactions, and form inputs. The most embarrassing bugs are often the ones that only appear on the device your first user has.
SEO basics are configured (title, description, OG image)
RecommendedSet a unique page title and meta description for your landing page. Add an Open Graph image so your app looks good when shared on social media. These take 10 minutes and significantly improve first impressions.
Replace launch anxiety with launch confidence
- Comprehensive readiness checks covering security, infrastructure, and compliance
- Stage-by-stage tracking so you know exactly what is done and what remains

Frequently asked questions.
For a solo builder, plan 1-2 weeks of focused pre-launch work after your app is functionally complete. This covers legal pages, payment testing, monitoring setup, and marketing preparation. Rushing through this phase leads to the preventable launch-day fires that derail momentum.
Yes. If you collect any user data (including email addresses), you need a privacy policy. If users create accounts or use your service, you need terms of service. This is not optional — GDPR, CCPA, and similar regulations apply from day one. Use a generator like Termly to create compliant pages quickly.
You can launch without payments if you are validating demand first. Offer a free beta and add payments later. But if you plan to charge at launch, test the full billing flow thoroughly — a broken payment flow is worse than no payment flow.
Build a small audience first if possible — even 50-100 interested people give you launch-day momentum. Start marketing months before release: create a landing page with a waitlist, share behind-the-scenes content, and engage early users for feedback. A Product Hunt launch without an existing audience often underperforms.
Make sure your core user flow works perfectly. A user should be able to sign up, experience your main value, and come back the next day without hitting a wall. Everything else — marketing, analytics, legal — supports this. If the core experience is broken, nothing else matters.
