Use this vibe-coded website launch checklist to test customer journeys, data permissions, API keys, payments, mobile usability and recovery before going live. A convincing preview is a starting point; it does not establish that the business can safely rely on the site.
Vibe coding means using natural-language instructions to generate and refine software. For a small business, start by writing one acceptance test: “A customer can request a quote and our team receives the correct details.” Add booking or buying only if needed. Every extra account, integration or database creates more to maintain.
1. Start your vibe-coded website launch checklist with an enquiry
Use invented test details. Submit the form, confirm delivery to the intended inbox or dashboard, and check the reply address. Try a missing required field, a long message and a failed connection. The confirmation should explain what happened without claiming success when delivery failed.
For example, a café’s catering form should preserve the event date and guest count, show a useful error if submission fails, and avoid sending the customer’s message to an unintended recipient. This is an illustrative test scenario, not a client result.
2. Check access beyond the screen
Test with two separate test accounts. Can customer A read or change customer B’s record by opening a copied link? Can a logged-out visitor reach an admin action? Hiding a button does not enforce permission.
Lovable’s security guidance explains that browser code is inspectable and that server-side functions still need authentication, authorisation and input validation. Ask a developer to verify the underlying checks; do not test against real customer records.
3. Separate public keys from secrets
A configuration variable is not automatically private. Anything delivered to the browser can be inspected. Private service credentials belong in a server-side secret store, with appropriate checks on the server.
The distinction depends on the service: Supabase’s API-key documentation permits publishable keys in public clients, with database access controlled through grants and row-level security. Secret keys bypass row-level security and must stay server-side. Do not remove a deliberately public key merely because it appears in the browser. If a private key has leaked, revoke or rotate it using the provider’s documented process.
4. Test unsuccessful payments too
If the website takes payments, use the provider’s sandbox to check successful payment, decline, cancellation and the resulting order state. Confirm that the server verifies payment before marking an order paid or releasing a paid feature. A thank-you page alone is insufficient evidence.
Stripe’s testing guide describes simulated transactions and test credentials. Use those rather than real card details or live charges. Check that the deployed integration’s mode and credentials match the intended environment before launch.
5. Check mobile, keyboard use and discoverability
On the deployed website, test a narrow phone screen and a larger display. Read the actual copy, open the menu, complete forms and check that the keyboard does not cover the submit action. Navigate by keyboard and confirm visible focus, clear labels and understandable errors.
Check descriptive page titles, working links and whether essential content is present when pages load. Search visibility needs its own diagnosis: our guide to a website missing from Google covers that separate issue.
6. Plan the first repair before launch
Record who controls the domain, hosting, source repository and service accounts. Keep a known working version and practise restoring it in a test environment. Assign someone to check failed submissions, errors, dependency updates and renewals.
Our view: launch when the important journeys have evidence behind them, rather than when the AI says the project is complete. A read-only brochure site and an application storing customer accounts need different levels of review.
Limitation: this checklist is not a security audit. Automated scans can miss business-logic failures; Lovable’s security overview also says its checks do not replace a thorough review. For accounts, personal data or payments, obtain an appropriate technical review before relying on the application.
If you need help deciding what that review should cover, contact byKlash with the site’s purpose and the customer journey you need to verify.
Frequently asked questions
You can build and launch simple sites with AI tools, but you still need to verify the deployed result. Bring in appropriate technical expertise when the website handles accounts, personal data or payments.
No. A scan is one piece of evidence. Test permissions and business workflows as well, and obtain a review proportionate to the information and functions involved.
No. Some services provide publishable keys for public clients. Private secret keys must stay server-side. Check the provider’s documentation and the access rules protecting the data.
Not for the customer-journey checks. Underlying security repairs depend on the application and its versions; a generic pasted snippet cannot verify that the whole system is safe.
