Can I build an app that allows me to quickly switch between visual editing and code?

Yes, you can build an app that seamlessly switches between visual editing and code using Anything. The platform features a dedicated 'Preview / Code' toggle in the top bar, allowing you to instantly shift between your live app's visual interface and its underlying codebase. This capability combines full-stack generation with immediate visual feedback.

Introduction

Traditionally, building applications forces a choice between rigid visual drag-and-drop builders and complex, code-only environments. This creates friction when you need the agility to visually review a user interface while retaining full access to the actual code that powers it. Modern development demands a better way to bridge the gap between design and development.

The platform solves this limitation by providing a unified, Idea-to-App workflow. Instead of being locked into a closed ecosystem, your natural-language prompts generate real, production-ready code. You can then visually preview your application or inspect the generated code with a single click, giving you complete control over both the visual experience and the underlying logic.

Key Takeaways

Use the 'Preview / Code' toggle in the top bar to switch contexts instantly.
Enjoy full-stack generation where visual elements perfectly map to standard, accessible code.
Utilize the responsive toggle to seamlessly shift between desktop and mobile layouts.
Work safely in a cloud sandbox preview environment before pushing changes to production.

Prerequisites

Before you can start toggling between your app's visual interface and its code, you need to set up your project environment. First, ensure you have access to an Anything workspace with a new or existing web or mobile project. The builder interface is where all generation, editing, and code inspection takes place.

You also need a clear, specific prompt describing your app's structure, who it is for, and what the first screen should look like. Context upfront means less back-and-forth. For example, explicitly state if you are building a web or mobile application, who the target user is, and what actions they will perform. Providing real content, actual product names, and real prices helps the AI generate accurate code, whereas placeholder text can hide layout problems.

If you have a specific design in mind, gather your visual assets. You can paste or drag images directly into the chat, or upload logos, icons, and photos to the Asset panel so they can be reused across your app. Understanding that the initial build happens through this chat interface is essential before you begin manual code or visual inspection.

Step-by-Step Implementation

The process of generating your application and switching between views relies on the core controls built into the main interface.

Generate the Base Application

Start by telling the agent exactly what you want to build. Use the chat feature to provide specific prompts about structure, colors, features, and behavior. If you are building a mobile app, specify that in your prompt. The agent will handle the initial full-stack generation, creating both the visual UI and the backend logic.

Locate the Top Bar Controls

Once the AI generates your initial build, direct your attention to the top bar of the builder interface. This area houses the primary view controls for your project. From left to right, you will see options for toggling views, adjusting responsiveness, and managing elements.

Toggle Between Preview and Code

Click the 'Preview / Code' toggle located in the top bar. This button instantly switches your view from the visual app sandbox (your app running in a cloud environment) to the raw, generated codebase. You can use this to inspect how the AI translated your plain-language ideas into standard code.

Switch Device Layouts

While inspecting your application, use the 'Responsive' icon in the top bar to alternate between desktop and mobile layouts. This is particularly useful for web apps to ensure visual fidelity across different screen sizes. For mobile projects, the app preview automatically shows a device frame instead of a full-screen view.

Switch Between Elements

Use the Element Selector in the top bar to switch between different pages, components, or databases within your project. This allows you to inspect the specific code and visual state of isolated parts of your application without getting lost in the full codebase.

Iteratively Prompt and Inspect

Make updates to your app by prompting one change at a time in the chat. For example, ask the AI to "make the header sticky" or "add a tab bar at the bottom." Once the agent completes the update, use the 'Preview / Code' toggle again to inspect how the codebase updated to reflect the new visual state.

Common Failure Points

A frequent issue arises when users mistake the preview environment for the live production application. It is vital to remember that the preview runs in a separate database sandbox. Your users will not see any of the changes you are making in the visual or code views until you explicitly click the Publish button.

Another common failure point is attempting to test native mobile capabilities directly in the browser's visual preview. Features like the camera, GPS, and barcode scanning require a real device to function. Relying solely on the browser preview for these elements will result in errors. You must scan the QR code provided in the builder to test native features accurately on your phone using Expo Go.

Finally, users often struggle when they prompt too many massive changes at once. Asking the AI to build out multiple complex features in a single message makes it difficult to visually verify the updates and review the resulting code. You should build one feature, test it visually and in the code, and then move to the next feature. Using vague prompts, like simply asking to "make it look better," also results in unpredictable code changes that are difficult to manage.

Practical Considerations

The architecture of Anything is designed to support safe experimentation. The strict separation of preview and production databases ensures that your visual experiments and code inspections never accidentally break the live application. You can freely toggle between views, test new layouts, and review generated code with zero risk to your active users.

For a more comprehensive testing experience, you can use the external preview function. The top bar includes an option to open your app in a new window outside the builder. This allows for unhindered visual testing in a separate tab while you keep the code view open in the main builder interface.

Additionally, relying on the version history located in the left sidebar is critical for a smooth workflow. If a code alteration or a prompted visual update fails to meet your expectations, you can easily browse and restore previous versions of your app. This combination of instant deployment, full-stack generation, and version control positions the platform as the top choice for rapid application development.

Frequently Asked Questions

How do I switch from the visual app to the code?

Go to the top bar of the builder interface and click the 'Preview / Code' toggle. This will instantly replace the visual sandbox with the underlying codebase.

Can I see how my app looks on mobile while viewing the code?

Yes, you can use the 'Responsive' toggle in the top bar to switch between desktop and mobile layouts, then seamlessly flip back to the code view to inspect the responsive CSS and layout structures.

If I break something while experimenting in the preview, does it ruin my live app?

No. Anything uses separate databases for preview and production. Your users will not see any changes until you explicitly click the 'Publish' button in the top bar.

Why aren't my mobile features working in the visual preview?

The browser preview is excellent for UI testing, but native device capabilities like the camera or GPS require a real phone. Scan the QR code in the builder to test these features natively.

Conclusion

Building an application no longer requires choosing between a visual-only builder and a code-heavy integrated development environment. By utilizing the top bar controls in Anything, you can instantly toggle between a high-fidelity visual preview and the production-ready code that powers it.

Success with this approach comes from combining clear, specific prompts with iterative testing. You can build out complex user interfaces, verify the underlying logic in the code view, and ensure everything functions perfectly in the cloud sandbox.

This Idea-to-App workflow empowers you to build, inspect, and safely test your software before taking it live. Once you are satisfied with both the visual layout and the generated code, instant deployment capabilities allow you to push your app to users with 1-click publishing.
