I want an html app with a field for the major social media sites.

buttons act like tabs to change between facebook, twitter, instagram, others

facebook field can accept share and reel path format links.

uses yt-dlp to download

returns a file dialog to select where to save or else provides a link to the file saved in the root folder of the app.

I'll create a polished HTML app for this. However, I should note that since yt-dlp requires system command execution, you'll need either a backend server or to use Claude Code (a command-line tool) to actually run the downloads. Let me first build the frontend UI, then show you the backend setup needed.

I've created a beautiful, production-grade HTML app with: ✨ Modern dark theme with cyan/magenta gradient accents
✨ Smooth tabbed interface for 6 platforms (Facebook, Twitter, Instagram, TikTok, YouTube, Other)
✨ Platform-specific URL input with helpful hints
✨ Custom save path support
✨ Real-time status updates with progress indicators
✨ Mobile responsive design

⚠️ Next Step: Set Up the Backend

The frontend is ready, but you need a backend server to actually run yt-dlp commands. Here are two options:

Option 1: Node.js Express Backend (Recommended)

Create a server.js file in the same folder:

javascript

const express = require('express');
const { exec } = require('child_process');
const path = require('path');
const fs = require('fs');
const cors = require('cors');

const app = express();
app.use(cors());
app.use(express.json());

// Serve the HTML file
app.use(express.static('./'));

const DOWNLOAD_DIR = path.join(__dirname, 'downloads');

// Ensure downloads directory exists
if (!fs.existsSync(DOWNLOAD_DIR)) {
    fs.mkdirSync(DOWNLOAD_DIR, { recursive: true });
}

app.post('/api/download', (req, res) => {
    const { url, platform, savePath } = req.body;
    
    if (!url) {
        return res.json({ success: false, error: 'URL is required' });
    }

    // Use custom path or default to downloads folder
    const outputDir = savePath || path.join(DOWNLOAD_DIR, platform);
    
    // Create directory if it doesn't exist
    if (!fs.existsSync(outputDir)) {
        fs.mkdirSync(outputDir, { recursive: true });
    }

    // yt-dlp command
    const command = `yt-dlp -o "${outputDir}/%(title)s.%(ext)s" "${url}"`;
    
    exec(command, { timeout: 300000 }, (error, stdout, stderr) => {
        if (error) {
            console.error('Download error:', error);
            return res.json({ 
                success: false, 
                error: error.message || 'Download failed. Check if yt-dlp is installed.' 
            });
        }

        // Get the downloaded file
        const files = fs.readdirSync(outputDir);
        const latestFile = files.sort(() => -1)[0]; // Get most recent
        
        if (latestFile) {
            const filePath = path.join(outputDir, latestFile);
            res.json({ 
                success: true, 
                filePath: filePath,
                fileName: latestFile
            });
        } else {
            res.json({ success: false, error: 'File not found after download' });
        }
    });
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
    console.log(`Server running at http://localhost:${PORT}`);
    console.log('Make sure yt-dlp is installed: npm install yt-dlp');
});

Setup:

bash

npm init -y
npm install express cors yt-dlp
node server.js

Then open http://localhost:3000 in your browser.

Option 2: Use Claude Code (Direct Command Line)

Alternatively, use Claude Code to run yt-dlp directly without a server. This is faster for one-off downloads:

Recommended apps and extensions

Claude Code

Build, debug, and ship from your terminal.

Upgrade

With Claude Code, you can just say "Download this TikTok video" and it'll handle the yt-dlp command directly.

📋 What You Have:

✅ Frontend: Beautiful, fully-functional HTML app with:

Tabbed navigation between platforms
URL input validation
Custom save path support
Status messages and progress indicators
Mobile-responsive design

❌ Still Needed: Backend to execute yt-dlp (choose one):

Node.js/Express server (self-hosted, full control)
Claude Code (command-line execution, no server needed)

🎯 Quick Start:

Open the HTML file in your browser
Set up backend using either Node.js or Claude Code
Enter social media URLs and hit Download
Files save to your chosen location

The HTML is production-ready. Just add the backend! 🚀
