How Hostinger Horizons Works: Behind the Scenes of AI Web App Creation

If you’re new to no-code tools or AI app generators, you might be wondering how Hostinger Horizons actually builds a working web application from just a written prompt. The answer lies in its powerful combination of artificial intelligence, real-time preview, and automatic code generation.

Understanding Prompt-Based AI Web App Generation

At the core of Hostinger Horizons is a prompt-based workflow—you simply describe what kind of app you want, and the AI generates it instantly. This could be anything from “Create a budgeting app with user sign-in and expense tracker” to “Design a booking system for yoga classes.”

Once you hit Enter, the AI interprets your request and starts building the UI, logic, and structure—all without manual coding. This is different from traditional drag-and-drop website builders because Horizons focuses on dynamic app features, not just static web pages.

With this approach, anyone can:

• Build a web app using prompts
• Launch ideas without hiring developers
• Customize app functionality by refining prompts step-by-step

What makes it more powerful is that you can continue refining the app using follow-up prompts. Want to change the layout? Add user authentication? Improve database logic? Just type it in, and Horizons updates the app in real-time.

Real-Time Editing and Live Preview in Dual Pane

The interface is divided into two interactive panes:

• Left pane: This is where you type and refine prompts to update the app’s features or interface.
• Right pane: This shows a live preview of your web app, allowing you to test interactions, click buttons, or switch between pages as you build.

This live editing experience makes Hostinger Horizons a powerful choice among no-code AI web app builders, especially for creators who want full control without touching code.

Limitations of the Current Beta Version

While the tool is impressively fast and intuitive, it’s important to note that Hostinger Horizons is still in early access. You might run into occasional bugs, especially when attempting complex logic or database integrations. However, the team is constantly rolling out updates.

You also get a 30-day money-back guarantee, which means you can test it risk-free and cancel anytime if it doesn’t meet your expectations.

If you’ve been searching for a no-code platform with AI, but find most tools either too technical or too limited, Horizons offers the best of both worlds—intelligent automation and human-friendly editing.

How to Build a Web App with Hostinger Horizons (Step by Step)

Let’s now walk through the exact process to build a functional web app using Hostinger Horizons. You don’t need any technical skills or programming background—just follow these steps and adjust your prompts as needed.

Step 1 – Sign Up and Choose a Hostinger Horizons Plan

Start by visiting the Hostinger Horizons official page and signing up for a plan. All pricing tiers include core features for AI web app development, such as prompt-based editing, preview mode, and hosting.

• Starting price: ₹1749/month
• Includes: One month free hosting, up to 1,000 AI message prompts, and early access features

Once you’ve completed the payment, go to your hPanel dashboard, then click:
Websites → Add Website → Hostinger Horizons.

This will launch your new web app project.

Step 2 – Define Your App’s Purpose with a Strong Prompt

This is the most important step when working with AI. Hostinger Horizons depends on well-structured prompts to generate your app correctly. The more detailed your input, the better the results.

Here’s what your prompt should include:

• App goal: What problem does it solve?
• Target audience: Who is it built for?
• Core features: What should users be able to do?
• Design preferences: Mention layout, color schemes, or UI inspiration

Example Prompt:

“Create a fitness app that recommends workout and meal plans based on user data like age, weight, and activity level. Include sign-up/login, a progress dashboard, and a clean, modern layout with a teal and white color scheme.”

You can build any type of app:

• Business apps without coding
• Personal productivity tools
• Simple mobile-first web apps
• Portfolio or client dashboards

After entering the prompt, Horizons will generate the basic structure instantly, which you can customize in the following steps.

Step 3 – Customizing Your App’s Design Without Code

Once your app’s basic structure is generated from the initial prompt, the next step is to customize the visual design and layout—no HTML, CSS, or JavaScript required. This is where Hostinger Horizons really shines compared to traditional web app development tools.

Using Prompts to Add Pages, Forms, Menus, and Buttons

The easiest way to personalize your app’s UI is by giving detailed instructions through prompts. For example:

• “Add a sidebar menu with links to Dashboard, Profile, and Settings”
• “Include a contact form on the homepage with name, email, and message fields”
• “Create a full-screen login page with a ‘Forgot Password?’ link”

Because Horizons is an AI-powered app builder, it understands natural language. You don’t need to manually design components or drag and drop. Just describe what you want and the platform will add it for you.

Some essential elements you might want to include:

• Navigation menus: Sidebars, top bars, hamburger menus
• Input forms: Email, phone, password, file upload, etc.
• Call-to-action buttons: Submit, Sign Up, Get Started
• Pages: About, Contact, Dashboard, Settings

Step 4 – Uploading Wireframes or Using Text-Based Descriptions

If you’ve already created a wireframe using tools like Figma, Adobe XD, or even a simple sketch, you can upload that visual reference while giving your prompt. This helps Hostinger Horizons produce more accurate UI layouts.

Alternatively, you can continue using detailed text-based prompts. Example:

“Design a homepage with a hero banner at the top, followed by three feature boxes in a horizontal row, and a footer with links to Terms and Privacy Policy.”

Using descriptive commands like these, you can build a complete web app interface without touching code, making this tool perfect for entrepreneurs and non-tech founders.

Step 5 – Design Tips for a Mobile-Responsive App UI

Many first-time users forget about mobile responsiveness, which is crucial in 2025 when over 60% of web traffic comes from mobile devices (source: Statista).

To ensure your app looks great across all screen sizes, you can add prompts like:

• “Make the layout mobile-friendly”
• “Ensure buttons are tap-friendly and have at least 44px height”
• “Use flexible grids instead of fixed widths”

If something looks off in the live preview, simply describe what needs fixing. The AI will re-render the layout based on your new input.

Step 6 – Improving Your App’s Logic and Structure for Better Functionality

After customizing the UI, the next step is to enhance the app’s functionality—how it behaves when users interact with it. With Hostinger Horizons, you can do this through plain English instructions instead of complex backend coding.

How to Set Up Business Logic and Conditional Flows

Business logic controls how your app responds to user data. For example, a task management app might move a task to “Completed” only if a checkbox is ticked. Horizons lets you implement this logic by giving follow-up prompts like:

“When a user clicks the Complete Task button, move that task to the Completed section and update the status label.”

You can also define conditional flows (if-this-then-that style logic):

• “If a user chooses ‘Vegan’ in the diet form, show only vegan meal plans.”
• “If login fails, display an error message and disable the Submit button for 30 seconds.”

This makes Hostinger Horizons a powerful tool for logic-based no-code app creation.

Handling User Actions and Data Events Without Programming

In traditional coding, handling user actions (clicks, scrolls, swipes) requires writing JavaScript or using event listeners. Here, you just describe what should happen when a user interacts with a component.

Examples:

• “When a user presses Submit, validate the email field and then redirect to the Thank You page.”
• “When the app loads, show a welcome popup for new users.”

For more advanced workflows, you can even request error messages, password validations, or custom alerts—all through prompts.

Testing Functionality in Real Time

One of the best parts of using an AI no-code app builder like Horizons is the real-time testing experience. As you refine your logic, the right pane shows an updated version of your app, where you can:

• Click through the flows
• Fill forms and submit data
• See if the logic executes as intended

If something doesn’t work right, simply go back to the left prompt pane and revise your instruction.

Pro Tip: Focus on improving one part of the app logic at a time. For example, work on login validation first, then move to dashboard calculations, then database syncing. This reduces confusion and gives you better results.

How to Connect Hostinger Horizons App with Supabase Database

If your web app requires data storage—such as saving user profiles, tracking form submissions, or enabling login/logout features—you’ll need a backend database. Hostinger Horizons supports this with Supabase, a scalable and beginner-friendly open-source alternative to Firebase.

Setting up a database for your Hostinger Horizons web app doesn’t require coding. You just need to follow a few simple steps and provide the AI tool with your API credentials.

Why You Might Need a Database for Your App

Databases allow your web app to store and retrieve information across sessions and users. If you want to:

• Let users create and manage accounts
• Save form responses
• Track user progress or activity
• Build admin dashboards or dynamic content

… then connecting a backend is essential.

Without a connected database, your app will only store data temporarily (in the user’s browser), which isn’t reliable for production-level use.

Setting Up Supabase for No-Code Web App Projects

Here’s how to quickly set up a Supabase database for your app:

1. Visit supabase.com and create a free account.
2. Click “New Project” and fill out the following:
   • Project name
   • Secure password for the database
   • Region close to your audience
3. Once the project is created, copy the following:
   • Project URL
   • API Key (from the “Project Settings → API” section)

These credentials are what you’ll use to connect Supabase with Hostinger Horizons.

Prompt Example: How to Connect Supabase in Hostinger Horizons

Now, return to your Hostinger Horizons project and give it a precise instruction like this:

“Connect this app to my Supabase database. Use the following credentials:
Project URL: your-project-url
API Key: your-api-key
Then create a table called users with fields: email (text), password (text), joined_date (timestamp). Connect this table to the login and signup forms.”

Horizons will automatically generate backend logic, configure your API connection, and bind the fields to your app’s form components.

Important Tip: Database integration is one of the more complex tasks in AI app development. Always test the form behavior after setup, and don’t hesitate to refine prompts until the backend works correctly.

This method is one of the easiest ways to create a no-code full-stack web app with Hostinger Horizons—perfect for developers and non-tech founders alike.

Final Testing and How to Publish Your Web App Live

Before making your web app public, it’s critical to go through a full functionality check. Hostinger Horizons gives you a real-time preview interface, but you should also test the app across browsers, devices, and user flows.

Checklist to Test Your Hostinger Horizons Web App

Here’s a quick checklist to ensure your application is ready for launch:

• Functional testing: Are all buttons, links, and forms working as intended? Try various scenarios.
• Login/authentication: If users need to sign in, test incorrect credentials, password resets, and logout flows.
• Mobile responsiveness: Open your app on different screen sizes to confirm layout adapts well.
• Cross-browser compatibility: Test on Chrome, Firefox, Safari, Edge, and Brave for visual or functional bugs.
• Data validation: Check if form fields validate correctly and data is saved to Supabase (if connected).

You can use free tools like:

• BrowserStack – for live browser testing
• Lighthouse in Chrome DevTools – for accessibility, SEO, and PWA audits

How to Publish Your Web App on Hostinger Horizons

Once everything looks good, click the Publish button on the top-right of your Horizons dashboard. This will deploy your app to a temporary Hostinger subdomain, where you can share it instantly.

If you want to connect a custom domain:

1. Go to the Websites section in your Hostinger hPanel.
2. Choose your project from the list.
3. Click Connect Domain and enter your domain name.
4. Update your domain’s DNS settings as shown.

Publishing your AI-generated app is not just easy; it’s scalable. You can update features anytime by reopening the Horizons editor and modifying prompts.

Real-World Example: Building a Fitness App with Hostinger Horizons

To bring everything together, let’s walk through a concrete example: how to build a personalized fitness and diet web app using Hostinger Horizons. This example highlights best practices for prompt engineering, feature setup, and design customization.

Prompt Breakdown for a Fitness & Diet Recommendation Tool

Start with a clear, detail-rich prompt that covers goals, inputs, and outputs. For instance:

“Create a fitness and nutrition web app that:
• Lets users sign up and log in securely.
• Collects user data (age, height, weight, gender, activity level, dietary preferences).
• Generates tailored workout routines (strength, cardio, flexibility) and meal plans (vegan, vegetarian, keto).
• Displays a progress dashboard with charts tracking weight and workout completion.
• Uses a modern UI with teal accents, sans-serif fonts, and mobile-optimized layouts.”

This single instruction covers:

• User authentication setup
• Form-based data collection
• Automated recommendation logic
• Interactive dashboard creation
• Mobile-responsive design prompts

Once you enter this initial prompt, Horizons will scaffold your app. Then refine step-by-step:

1. Data Collection Forms: “Add dropdown fields for gender and dietary preference; make sure each field is required and displays an error if left blank.”
2. Recommendation Logic: “If the user selects ‘keto,’ generate meal plans with low-carb options only. Otherwise, show balanced meals with macros.”
3. Progress Dashboard: “Create a dashboard page that shows weight progress as a line chart and workout completion as a bar chart.”
4. Styling Touches: “Change the primary button color to teal and add hover effects; use Roboto font throughout.”

By breaking prompts into focused chunks, you guarantee each feature works flawlessly. This method of iterative prompt refinement ensures your no-code fitness app functions exactly as intended.

Features to Include: Dashboard, Progress Tracker, Input Forms

Key features for any health-focused web app:

• Secure Sign-Up & Login
• Dynamic Input Forms for personal metrics
• Automated Workout & Meal Plan Generation

• Customizable Notifications (e.g., “Time for today’s workout!”)
• Profile Management (update goals, preferences)

Because Hostinger Horizons is an AI app builder for fitness, you can add or tweak these components at any time by updating prompts and seeing live changes instantly.

Tips to Make Your App Look Professional and Functional

• Use Consistent Color Palettes: Stick to two to three brand colors for a cohesive look.
• Prioritize Mobile UX: Ensure buttons are large enough for touch and forms stack vertically on small screens.
• Include Tooltips & Help Text: Add brief descriptions under form fields so users know exactly what data to input.
• Test Data Flows: Enter dummy data and verify it’s saved in Supabase. Then, check retrieval and chart rendering.
• Gather User Feedback: Share your app link with friends or team members, collect feedback, and refine prompts accordingly.
