# Build a web app A complete example of building and shipping a web app in GenVibe. We'll build a **SaaS landing page with a waitlist form**. ## 1. First prompt > Build a modern SaaS landing page for a product called "Inboxly" — an AI email assistant. Include a hero with a headline and call-to-action, a features section with three cards, a pricing section with two tiers, and a footer. Add a waitlist form that collects an email address. ## 2. Refine the look > Use a dark theme with a purple accent color. > Make the hero headline bigger and add a subtle gradient background. > Add logos of "trusted by" companies as grayscale placeholders. ## 3. Make the form work Connect [Supabase](/integrations/supabase.md), then: > Use Supabase to store waitlist emails, and show a "You're on the list!" message after submitting. ## 4. Polish for mobile > Make sure everything looks good on mobile — stack the feature cards and shrink the hero text on small screens. ## 5. Deploy Connect Netlify and deploy for a live URL. {% content-ref url="/pages/cHGLDu0PBlw8uuOobBoF" %} [Deploying your app](/features/deployment.md) {% endcontent-ref %} ## Recap You went from one sentence to a deployed, working landing page with a real backend — using only chat. The same loop scales to dashboards, tools, and full apps. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
