Ever had AI write you a working HTML/CSS/JavaScript app in seconds, and just wanted to run it right now, on the phone in your hand? HTML Opener is a dedicated runner that lets you execute AI-generated web code, games, tools, and dashboards โ€” built with your favorite AI coding assistant โ€” as a real browser (WebKit) directly on iPhone. No computer required. WHAT IT SOLVES - The Files app only shows HTML as a static document โ€” no buttons, no animation, no JavaScript - Safari has no address bar option to open a local file:// path - Copy-pasting a project with a separate style.css or an images folder breaks the layout - Spinning up a local server on your Mac just to check something on your phone is overkill REAL BROWSER RENDERING Built on iOS's native WKWebView engine. Tailwind CSS, Three.js, Canvas animations, and modern JavaScript all render exactly as they would in a real browser. OPEN A WHOLE PROJECT FOLDER Select a folder containing style.css, app.js, and an images directory alongside your HTML โ€” every relative path resolves automatically. The layout that broke when you copy-pasted the code now renders perfectly. FULLSCREEN MODE Hide the header and margins and let the web content fill the entire screen. AI-built games and tools feel like a real installed native app, not a preview. FOUR SIMPLE ACTIONS 1. Open a file or folder 2. Jump back to any file you've opened before (Quick Switcher) 3. Auto-launch your favorite tool the moment the app opens 4. Settings for display, dark theme, and more WHO IT'S FOR - Anyone using AI to write code who wants to test it on the spot - Students learning to code who want instant feedback - Designers and developers checking mockups on a real device - Marketers reviewing an AI-drafted landing page on their own phone PRO (ONE-TIME PURCHASE, NOT A SUBSCRIPTION) Removes ads completely. Pay once, keep forever. Compatible with iPhone and iPad, iOS 17.0 or later. Stop opening your laptop just to check something. Open it in HTML Opener instead.
