• SendGrid or Resend API: To securely deliver downtime alert emails to the user.

How to Make It

• Build a simple dashboard where authenticated users can add, edit, or delete URLs they want to monitor.
• Create a backend cron job that runs every 5 minutes, iterating through the database of URLs and sending a GET request to each.
• Write error-handling logic so that if a URL returns a 404 or 500 status code (or times out), the system logs the downtime event in the database.
• Trigger an automated email alert to the account owner using your email API, and display the historical uptime percentage on their frontend dashboard.

• Use a headless browser instance (like Puppeteer) in the background to render the HTML template, take a pixel-perfect screenshot, and output it as a JPEG buffer.
• Implement a strict caching layer using Redis so that if the exact same URL parameters are requested twice, the image is served instantly from the cache rather than re-rendering the browser.

4. Browser Extension for AI Text Expansion

This project bridges local browser execution with cloud subscription models. You will build a Chrome extension that allows users to type short trigger words (like /intro) which instantly expand into long-form, AI-optimized paragraphs synced across all their devices.
