The exciting part of an AI-built website is how quickly something appears on screen. The less exciting part is discovering after launch that the contact form does not save submissions, a private page is public, or the mobile menu covers the main button. A convincing preview is the beginning of launch testing, not the end.
This checklist reflects a current shift toward agents that edit projects and produce deployable previews. Netlify documents agent-assisted build and preview workflows, while Cursor documents cloud coding agents. The workflow below is deliberately provider-independent: build separately, inspect the result, test real behavior, then choose what reaches production.

Start with a Launch Brief, Not Another Prompt
Write one sentence describing who the site serves and what visitors should do. Then list the pages, forms, integrations, and private areas required for that action. A portfolio, a tool directory, and a customer portal have different launch requirements even if an agent can make them look similar.
For a first release, choose one primary visitor action. Define an acceptance test in observable terms: “A visitor can submit this form, see a truthful success state, and the team can retrieve the submission.” “The page looks professional” is a useful design goal but not a functional test.
1. Keep the Working Prototype Separate
Use version control and save a recoverable baseline before asking an agent for broad changes. Make work on a separate branch or an equivalent isolated preview. Review what changed, including dependencies, configuration files, and generated assets, rather than looking only at the homepage.
Separate local-agent and cloud-agent assumptions. Cursor's current Run Modes documentation describes local execution controls and notes that cloud agents use a different execution model. A setting you rely on locally is not proof that a remote agent has the same restrictions.
If you are evaluating tools, explore Cursor for coding assistance and compare its current permission controls with the way you want to work. No agent setting replaces backups, review, or appropriately scoped credentials.
2. Understand What the Agent Can Reach
List the repositories, deployment projects, data sources, and third-party accounts available to the agent. Use test credentials and synthetic records for the first deployment. Do not attach a production customer database merely to make a demo feel realistic.
Cursor's cloud-agent security documentation discusses autonomous command execution and prompt-injection risk. The practical lesson is to review access deliberately: content read from a repository or website should not become authorization for unrelated actions.
Keep secret keys out of browser-delivered code and public repositories. If you are not sure whether a key is safe to expose, stop and check the provider's documentation. A successful build does not prove the absence of exposed secrets or unsafe permissions.
3. Build a Small Launch Test Matrix
Test the path a visitor takes from arrival to completion. Include at least a narrow phone layout, a desktop layout, keyboard navigation, and the site's light and dark themes if both are offered.
- Navigation: every main link, mobile menu, back link, and footer destination works.
- Forms: required fields, invalid inputs, successful submissions, and failures behave honestly.
- Actions: buttons look clickable and lead to the promised destination.
- Content: names, images, prices, disclosures, and claims are accurate or appropriately qualified.
- Access: private content is not accessible just by guessing a URL.
- Recovery: you know how to restore the previous working release.
Assign one person to record the test result and evidence. Avoid “I think that worked” entries. Note which browser or device you used and what remains untested.
4. Verify the Form's Destination
A success toast proves only that the interface showed a success toast. Submit a distinctive test message through the deployed preview and find it in the actual receiving service. Confirm that the stored fields are the ones your team needs.
Then test a failure: temporarily use a safe test configuration that returns an error, or use the service's supported testing method. The page should explain that delivery failed, preserve useful input where appropriate, and avoid implying that the team received a message it did not receive.
Do not replace a working form merely because a generated alternative looks newer. Record the current integration first, preserve its form name or endpoint where required, and verify the change with a real test submission.
5. Use Previews as a Review Boundary
Netlify Deploy Previews let reviewers inspect changes before production publication. Explore Netlify if that fits your hosting workflow. Check the exact build command, output settings, environment variables, and production branch for your project rather than copying another site's configuration.
A preview is not automatically confidential. Netlify's deploy overview distinguishes preview types and access protections. Use the appropriate access controls for sensitive work. A search-engine noindex instruction is not a password and does not prevent someone with a link from viewing a page.
6. Check Search and Sharing Before Launch
Give each important public page its own useful title and description. Confirm its canonical URL, image alternatives, heading structure, and internal links. A sitemap should contain the intended public pages, not draft routes or browser-only personal workspaces.
Open a page's rendered output and check the social image URL. Make sure the image actually loads and that centered text survives the square crops used by some sharing surfaces. Do not mark up invented reviews or ratings just to make a search result appear richer.
Test unknown URLs too. A missing article or product should return a meaningful not-found result, not silently present a different page as though it were the requested content.
7. Put a Ceiling on Cost and Complexity
Separate hosting usage, model usage, storage, email delivery, and other paid services. Decide which limits and alerts are available on your current plans. Do not assume a free development experience means a live integration has no ongoing cost.
If a feature needs a backend but none is connected, label its limitations honestly. Browser-only saved data should not be described as an account with cross-device sync. A form collector is not automatically an email marketing system. Ship a narrower working feature instead of a broader simulated one.
8. Publish a Small, Reversible Release
Identify the version you are publishing, keep the previous working version recoverable, and choose a time when someone can check the result. After release, repeat the primary visitor action on the public domain. Check navigation, the receiving service, and any important redirect.
Use the hosting provider's documented rollback process if a release breaks a critical path. Remember that returning to an older frontend does not necessarily undo database migrations, external messages, or other side effects. Plan those separately before introducing them.
A Practical Launch Record
Keep a short record with the release purpose, approved preview, tests completed, known limitations, public verification, and recovery owner. For a simple brochure site, this can be one page. For a more complex app, attach logs and test results without including credentials or customer information.
Frequently Asked Questions
Can I launch a website entirely built with AI?
Yes, but the origin of the code does not change your responsibility to test functionality, access, content, and operating costs. The right review depends on what the site can do and which data it handles.
Does a successful production build mean the site is secure?
No. Compilation and type checks catch particular classes of problems. They do not establish that database permissions, authentication, dependencies, secret handling, or business logic are secure.
What if I only want a landing page?
Keep the release small. Test its links, contact flow, mobile layout, accessibility basics, and sharing metadata. Avoid adding a database or agent integration unless the page actually needs it.
