HTML Viewer - HTML, JS, CSS Editor and Runner

Want to see your HTML, CSS, and JavaScript come to life instantly, without leaving your phone? This is the tool that turns your Android device into a fully functional code editor and live preview engine. No server, no upload, no fuss.

Core Editing & Preview Tools

• Live Code Execution: Every keystroke updates the rendered page in real time, showing you the exact output of your HTML, CSS, and JavaScript simultaneously.
• Syntax Highlighting & Line Numbers: Code is color-coded for HTML tags, CSS properties, and JS functions, with numbered lines for easy navigation and debugging.
• Built-in File Manager: Create, rename, delete, and organize .html, .css, and .js files directly on your device’s storage, all within a clean folder tree interface.
• Dual-Pane Split View: Edit your source code on one side while viewing the live rendered webpage on the other, with adjustable panel sizes for optimal workspace.
• Quick Insertion Tools: One-tap buttons to add common HTML structures (div, table, form), CSS rules (margin, padding, border), and JS functions (alert, console.log, for loop).

Key Advantages

• Zero Dependencies: No internet connection required to edit or run code – everything processes locally on your device.
• Lightweight & Fast: App size under 10 MB, launches instantly, and handles complex scripts without lag on devices running Android 5.0+.
• Full Offline Access: All your projects are saved locally; you can open, edit, and run them even in airplane mode.
• Export & Share: Save your finished pages as standalone .html files or share them directly via email, messaging apps, or cloud storage.
• No Ads During Editing: The interface stays completely clean while you code – no banners, no pop-ups, no distractions.

We suggest trying HTML Viewer for rapid prototyping, learning front-end development on the go, or quickly testing code snippets. You might enjoy the instant feedback loop and the ability to run full web apps without any backend server. Consider downloading this app if you want a portable, offline-capable code sandbox for your Android device.

Technical Disclaimer: This app requires an active internet connection for initial download and optional cloud features. Code editing and local preview work fully offline. In-app purchases may be available for premium themes, advanced export options, or extended file storage. All data is stored locally on your device unless you choose to export or share.
