Tell Me When Down is an uptime monitoring and security scanning tool specifically designed for solo founders and developers building with AI agents. Rather than just checking if a URL responds, it monitors your application across three distinct operational depths to ensure both availability and safety.

The platform inspects your project through three layers:

Public URL Scan: A free security scan evaluating your public domain for SSL issues, response headers, DNS configuration, and domain spoofing risks.
GitHub Code Scan: A read-only GitHub App that analyzes your codebase to detect known vulnerabilities (CVEs) and leaked secrets.
SDK Integration: Deep monitoring for critical backend components, including databases, Stripe webhooks, and background cron jobs.

With 60-second uptime checks and plain-English alerts, Tell Me When Down simplifies maintenance. Instead of requiring deep security expertise, every issue detected comes with a pre-formatted fix. Users can simply click "Copy for your AI tool" to feed the precise resolution directly into the AI coding agent used to build the application.
