Create a **new repository** on GitHub (recommended name: `status`).  \n2. Add a blank `index.html` file (n8n workflow will later update this file).  \n3. Go to your repository → **Settings** → **Pages**.  \n4. Under **Source**, select the branch (`main` or `master`) and folder (`/root`).  \n5. Save changes.  \n6. Your status page will now be live at: `https://<USERNAME>.github.io/status`\n\n\n## ✅ Prerequisites  \n- An **n8n instance** (self-hosted or cloud).  \n- A **GitHub account & repository** (to host the status page).  \n- A **Gmail account** (or any email service supported by n8n – example uses Gmail).  \n- Access to the target **website URL** you want to monitor.  \n\n---\n\n## ⚙️ How it Works  \n1. **Schedule Trigger** → Runs every 2 minutes.  \n2. **HTTP Request** → Pings your website URL.  \n3. **Switch Node** → Evaluates the response status (200 OK vs error/503).  \n4. **Code Node** → Generates a dynamic **HTML status page** (Up/Down).\n5. **GitHub Repo & File** → Github Repo Name Should be `https://github.com/<OWNER_NAME>/status` (recommended) & Must have(required) a blank file named as `index.html` before triggering this flow.\n5. **GitHub Node** → Updates/commits the `index.html` file in your repository.  \n6. **Gmail Node** → Sends an email alert if the site is down.  \n\n---\n\n## 🚀 How to Use  \n1. Import the workflow JSON into your **n8n instance**.  \n2. Configure credentials for:  \n   - **GitHub** (Personal Access Token with repo permissions).  \n   - **Gmail** (or your preferred email service).  \n3. Replace the following:  \n   - `https://app.yourdomain.com/health` → with your own website URL.  \n   - `example@gmail.com` → with your email address (or distribution list).  \n   - GitHub repo details → with your repository where `index.html` will live.  \n4. Deploy the workflow.  \n5. (Optional) Enable **GitHub Pages** on your repo to serve `index.html` as a live status page.  \n\n---\n\n## 🛠 Requirements  \n- n8n v1.0+  \n- GitHub personal access token  \n- Gmail API credentials (or SMTP/email service of your choice)  \n\n---\n\n## 🎨 Customising this Workflow  \n- **Interval** → Change schedule from 2 minutes to any desired frequency.  \n- **Email Content** → Modify HTML alert template in the Gmail node.  \n- **Status Page Styling** → Edit the HTML/CSS in the Code node to match your branding.  \n- **Error Handling** → Extend Switch node for other status codes (e.g., 404, 500).  \n- **Multiple Websites** → Duplicate HTTP Request + Switch nodes for multiple URLs.  \n\n---\n\n## 👤 Who Can Use It?  \n- **DevOps & SRE Engineers** → For automated uptime monitoring.  \n- **Freelancers/Developers** → To monitor client websites.  \n- **Startups & SMEs** → For a free, lightweight status page without paid tools.  \n- **Educators/Students** → As a hands-on learning project with n8n.  \n\n---\n\n## 🌟 Key Features  \n- 🔄 Automated uptime checks (configurable interval).  \n- 📧 Email notifications on downtime.  \n- 📝 Dynamic HTML status page generation.  \n- 🌍 GitHub Pages integration for public visibility.  \n- ⚡ Lightweight & cost-effective (no paid monitoring tool needed).  \n\n---\n\n## 🔗 Tools Integration  \n- **n8n** – Orchestration & automation.  \n- **GitHub** – Version control + hosting of status page.  \n- **Gmail** – Email notifications.  \n- **HTTP Request** – Website availability check.  \n\n---\n\n## 📈 Example Use Cases  \n- Personal website monitoring with public status page.  \n- Monitoring SaaS apps & notifying support teams.  \n- Internal company services uptime dashboard.  \n "
