HTML Opener: Web Code Runner
Open Real Pages, Not Raw Text
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Fix raw code dumps on iPhone. Run local HTML, AI-generated web apps, CSS, and JS in a real WebKit browser. No PC, no terminal, and no local server needed.
When you open an HTML file in the iPhone Files app, iOS just dumps lines of raw code on your screen. Buttons do not work, styles break, and Safari cannot open local file links.
HTML Opener fixes that. It runs your local HTML, CSS, JavaScript, and images in a real WebKit browser directly on your iPhone and iPad. No Mac, no terminal, and no local server required.
WHAT IT SOLVES
- Files app dumps raw code and text on screen instead of rendering the webpage
- Safari has no address bar option to open local file:// links
- Opening a single file breaks CSS styles and image assets in neighboring folders
- Setting up a local server on your computer just to check mobile layout is tedious
REAL WEBKIT BROWSER RENDERING
Built on iOS's native WKWebView engine. Buttons, forms, CSS styling, canvas animations, and modern JavaScript run exactly as they would in Safari.
OPEN AN ENTIRE PROJECT FOLDER
Select a folder containing style.css, script.js, and an images directory alongside your HTML file. All relative file paths resolve automatically with zero broken images or missing styles.
DESKTOP & MOBILE VIEW TOGGLE
Switch between phone layout and 1024px desktop view with a single tap. Review horizontal dashboards, data tables, and desktop web tools without broken layouts.
FULLSCREEN MODE
Hide navigation bars and margins to give your web content the entire display. Web apps and tools feel like installed native apps.
FOUR SIMPLE ACTIONS
1. Open a local file or folder
2. Quick Switcher to jump between recent projects
3. Auto-launch your primary tool as soon as the app starts
4. Clear cache, toggle dark theme, and customize display options
WHO IT IS FOR
