A step-by-step guide to creating a no-code web app with Hostinger Horizons

Thanks to Hostinger Horizons’ powerful AI chatbot, creating a no-code web app is straightforward and requires just a few steps.

Step 1: Define your web app

To ensure your web app meets your goals and expectations, create a clear plan, including its core purposes, features, and how you plan to measure success:

• Form ideas. Start with the basics. What problems are you trying to solve? Who is the target audience? How will users interact with your app? Knowing the fundamentals helps you avoid unnecessary adjustments with Horizons’ AI assistant and streamlines the development process.
• Clarify purpose. Zoom in on your web app's vision. What is essential for functionality and usability? Which key values are critical in guiding development? Are the planned designs and formats appropriate for the target audience? With a clear direction, you can prevent inconsistency and optimize goal performance.
• Plan features. List the features you need to build a successful app. Which functions improve engagement and user satisfaction? What technical requirements are necessary to support these functions? Are your chosen features likely to efficiently facilitate user needs? A strong understanding of the essential features before development ensures user approval from day one of launch.
• Monitor success metrics. Decide how you’ll measure performance. What indicators are critical to app success? Should you use analytics tools, surveys, or heatmaps to monitor user behavior? How can you use collected data to improve your web app? Clear success metrics allow you to identify and correct performance issues quickly.

To build a premium-quality no-code app, remember to start with a minimum viable product (MVP), prioritize user experience, ensure scalability, and continuously gather feedback.

Step 2: Build your app

Once you have a solid strategy, start building your web app with Hostinger Horizon’s no-code development process:

• Use the AI chat interface. Horizons offers an AI-powered chatbot to guide you through the app creation and simplify development. Describe your needs in a prompt, and the AI will generate the app for you. Keep instructions clear and concise for the best results.
• Try voice commands. The web app builder supports voice commands for accessibility and convenience. Select the microphone icon on the left side of the prompt interface and say your instructions out loud to avoid typing. Plan what you want to say before clicking to avoid redos.
• Upload images. The AI assistant handles and analyzes image uploads. Click the attachment icon at the bottom left and choose an image. This feature allows you to provide UI sketches and error screenshots for accurate designs and quick bug fixes.
• Test in a sandbox. The no-code solution has sandboxing capabilities to ensure a smooth user experience before launch. Interact with the app as a regular user, testing all functionalities and experimenting with various use cases. Note issues immediately to prevent even the most minor bugs from being overlooked.
• Make changes. Horizons can adjust initial builds with additional prompts. Leverage the results from your sandbox testing to alter layouts, edit existing features, and optimize performance. Remember, you can upload images to demonstrate your needs better and get more accurate results.

For the best outcome possible, begin each prompt with an action word, explain the core purpose, and list all key features. For example, “Build an app for booking appointments. It should include a calendar, payment integration, and automated email confirmations.”

Step 3: Prepare to launch

With your app built and refined, the final step is preparing for a smooth and successful launch:

• Create a pre-launch checklist. Consider user interface, back-end functionality, and security settings to ensure all elements are in place. Double-check your app's core functions and designs to avoid last-minute issues.
• Test requirements. Interact with your web apps’ features like a regular user, considering security, compatibility, and usability. Initial tests often help you discover and address technical flaws for a more stable, reliable web app.
• Optimize performance. Reduce load times, ensure mobile responsiveness, and aim for intuitive navigation. Horizon includes performance automation and AI insights to simplify building a fast, professional, smooth-feeling web app.
• User feedback integration. Use Hostinger Horizons' sandbox to collect valuable insights from beta user testers, accounting for your target demographics, devices, and features. The more thorough the pre-launch testing, the more effectively you can identify bugs and usability concerns to guarantee a seamless customer experience.

When you are fully satisfied with your web app, click the Deploy button. Horizons will then automatically publish and host your app.

Understanding web apps

A web app is an online digital tool that users can engage with through the Internet, unlike native apps, which require software installation. Although web apps and traditional websites are easily confused, some crucial differences exist.

Web apps offer dynamic features that enable user interaction. They let you fill out forms, make orders, or use specialized tools directly in your browser. Google Docs, WordPress, Shopify, and Canva are all examples of web apps.

Traditional websites are mainly for information, offering static content like text, images, and video with little to no interaction support. Wikipedia, WebMD, National Geographic, and NASA use traditional websites.

In the modern day, web apps are the more popular choice, offering a range of additional benefits compared to static sites, including:

• Real-time engagement. Live updates, instant messages, and other dynamic features to enable user interaction and enhance communication
• Flexibility and accessibility. Support app access for users anywhere with an internet connection
• Cross-platform collaboration. Consistent performance across different operating systems and devices without needing separate pages or web apps
• Cost-effective maintenance. Reduce development and maintenance costs with centralized updates and fewer compatibility issues.
• Instant feedback. Provide immediate responses to user actions for smooth and efficient interactions.
• Improved user experience. Create an overall more engaging, personalized, and intuitive user journey thanks to the dynamic nature of web apps.

Now that you understand the benefits of web apps let's explore how to create the best possible web app using Hostinger Horizons.
