# 🚀 Deploy SafetyMaster Pro to Render (Free) ## Why Render? - **Free tier**: 512 MB RAM, automatic HTTPS, zero-downtime deploys - **Easy setup**: Similar to Railway, just connect your GitHub repo - **No credit card required** for free tier - **Perfect for Flask apps** with AI models ## 📋 Prerequisites - GitHub account with your SafetyMaster Pro code - Clean repository (large files already removed via .gitignore) ## 🔧 Step 1: Prepare Your App Your app is already configured for cloud deployment! The existing files work perfectly: - ✅ `Dockerfile` - Ready for containerized deployment - ✅ `requirements.txt` - Python dependencies - ✅ `web_interface.py` - Uses PORT environment variable - ✅ `.dockerignore` - Excludes unnecessary files ## 🌐 Step 2: Deploy to Render ### Option A: Web Interface (Recommended) 1. **Sign up**: Go to [render.com](https://render.com) and create free account 2. **Connect GitHub**: Link your GitHub account 3. **Create Web Service**: - Click "New +" → "Web Service" - Select your SafetyMaster repository - Choose "Docker" as environment - Set service name: `safetymaster-pro` ### Option B: Using render.yaml (Advanced) Create `render.yaml` in your project root: ```yaml services: - type: web name: safetymaster-pro env: docker plan: free dockerfilePath: ./Dockerfile envVars: - key: PORT value: 10000 - key: PYTHONUNBUFFERED value: 1 ``` ## ⚙️ Step 3: Configuration ### Environment Variables (if needed) - `PORT`: Automatically set by Render - `SECRET_KEY`: Add your own secret key for Flask sessions ### Build Settings - **Build Command**: Automatically detected from Dockerfile - **Start Command**: Automatically detected from Dockerfile ## 🎯 Step 4: Deploy 1. **Push to GitHub**: Make sure your latest code is pushed 2. **Auto-deploy**: Render will automatically build and deploy 3. **Monitor**: Watch the build logs in Render dashboard 4. **Access**: Your app will be available at `https://safetymaster-pro.onrender.com` ## 📊 Expected Performance ### Free Tier Limits - **RAM**: 512 MB (sufficient for your Flask app) - **CPU**: 0.1 CPU units (shared) - **Storage**: Ephemeral (files reset on restart) - **Bandwidth**: 100 GB/month - **Build time**: 15 minutes max ### AI Model Considerations - Models download automatically on first run - May take 2-3 minutes for first startup (cold start) - Subsequent requests are fast - App sleeps after 15 minutes of inactivity (free tier) ## 🔧 Troubleshooting ### Common Issues 1. **Build timeout**: Models are too large - Solution: Models download at runtime (already configured) 2. **Memory issues**: App uses too much RAM - Solution: Optimize model loading in `safety_detector.py` 3. **Slow startup**: First request takes time - Solution: Normal behavior, subsequent requests are fast ### Optimization Tips ```python # In safety_detector.py - already implemented # Models download only when needed # Efficient memory usage # Automatic cleanup ``` ## 🆓 Alternative Free Hosts If Render doesn't work, try these: ### 1. Fly.io - **Free tier**: 3 VMs, 3GB storage - **Setup**: `flyctl launch` (requires credit card) - **Pros**: Better performance, global edge ### 2. Koyeb - **Free tier**: 1 web service - **Setup**: Connect GitHub repo - **Pros**: No credit card required ### 3. PythonAnywhere - **Free tier**: 512MB storage - **Setup**: Upload files manually - **Pros**: Python-focused, very simple ## 🎉 Success! Once deployed, your SafetyMaster Pro will be live at: `https://your-app-name.onrender.com` Features available: - ✅ Real-time safety monitoring - ✅ PPE detection (Hard Hat, Safety Vest, Mask) - ✅ Violation alerts - ✅ Web dashboard - ✅ Image capture ## 📞 Need Help? - **Render Docs**: [render.com/docs](https://render.com/docs) - **Community**: [community.render.com](https://community.render.com) - **Support**: Free tier includes community support --- **Ready to deploy?** Just push your code to GitHub and connect it to Render! 🚀
