Test an AI-built app before launch
How to test a vibe-coded app before launch: pick the critical public paths, run real browser checks, fix what breaks and share evidence before traffic arrives.
Article
AI coding tools make launch velocity feel cheap. The risk is that the launch page, signup flow, onboarding screen, pricing page, or contact form quietly broke while the product still looks good in screenshots.
Before launch, test the paths that determine whether a visitor trusts you.
The five launch paths
Start with public, non-destructive pages:
- homepage loads and the main CTA is clickable
- pricing renders the right tiers and CTAs
- signup or waitlist accepts test data
- contact or demo request returns a success state
- docs, FAQ, or help links do not dead-end
Do not start with private dashboards, billing payment submission, or destructive admin flows unless you have explicit permission and a safe test environment.
Turn each path into a one-sentence goal
Useful goals are concrete:
- "Open the homepage, click Pricing, and confirm the pricing cards render."
- "Submit the waitlist form with test data and confirm the success message."
- "Click each top navigation link and capture screenshot evidence after each page change."
Weak goals are vague:
- "Check the site."
- "Make sure everything works."
- "Look around."
The browser can only prove what the goal names.
Capture proof, not vibes
A good launch test creates an artifact:
- the target URL
- the goal
- every browser step
- screenshots after movement
- an honest pass, fail, partial, or unavailable state
- a share link for the founder, PM, or QA reviewer
That artifact matters because launch decisions are social. Someone needs to see what was tested without opening logs.
Use proof pages as your launch checklist
For a small launch, run one proof page per critical path. For a larger launch, save approved scenarios and rerun them before posting the launch.
The minimum bar is not "all possible bugs are gone." The minimum bar is "the paths we are asking customers to use have visible evidence."
What to do when a proof fails
Do not hide it. Failed proof pages are useful because they show exactly where the launch path broke.
Fix the issue, rerun the same goal, and keep the passing proof page attached to the launch checklist. If the browser could not run because the environment was unavailable, treat that as a launch blocker too.
The launch rule
If the page is important enough to promote, it is important enough to test with a real browser.
Start with one bounded check at /check, no card needed. Plans and prices are on /pricing.
