New: Browser-to-Unreal bridge support. HTML pages can now send commands back to Unreal Engine, including Blueprint event triggering. Updated documentation included. (Check Documentation)

Easy HTML Launcher is a lightweight runtime plugin for Unreal Engine that makes it easy to work with HTML from Blueprint. Instantly open HTML in the user's default browser, save HTML files with a native Windows folder picker, and now send commands back from the browser into Unreal through a built-in localhost bridge.

Perfect for developers who want simple web-powered workflows without building a full embedded browser UI.

What can you do with it?

🌐 Launch HTML In Browser

Pass any HTML string to a Blueprint node and instantly open it in the user's default browser. Great for help pages, changelogs, patch notes, formatted reports, dashboards, and AI-generated web interfaces.

💾 Save HTML To File

Open a native Windows folder picker, let the user choose where to save the file, and optionally auto-open the saved HTML in the browser.

📁 Open Folder Picker Dialog

Use the standalone folder picker node anywhere you need native folder selection in your project.

🔁 Browser-to-Unreal Command Bridge

Start the built-in command server in Unreal and let buttons inside your HTML page send commands back into the engine. Trigger Blueprint events, pass payloads such as level names, test connectivity with ping requests, and optionally run console commands.

Use Cases:

- External HTML start menu or launcher

- AI-generated web UI that controls gameplay or tools

- Help pages, changelogs, patch notes, and documentation

- Printable receipts, summaries, and export pages

- HTML reports generated from game or application data

- Web-based dashboards and utility tools

Why Easy HTML Launcher?

- Pure runtime implementation - works in packaged builds

- Windows-native folder dialogs

- Simple Blueprint workflow with minimal setup

- Browser-to-Unreal bridge for Blueprint event triggering

- Great for non-coders and AI-assisted HTML generation

- Lightweight and focused - no unnecessary bloat

Platform:

- Windows (Win64)

Create browser-based UI flows from Unreal in minutes - from simple HTML pages to interactive web panels that can talk back to your game.
