Our story

AlertsDown focuses on a straightforward problem: checking public websites and API endpoints continuously, preserving useful history, and notifying the right contacts when a check or SSL certificate fails.

Free Builders supports 10 monitors with email alerts. Paid plans add faster checks, higher quotas, more notification channels, and full MCP and API access.

Mission & promise

  • Visibility without noise: Deliver the signal you need, when you need it.
  • Customer empathy: Every feature is measured against real downtime stories.
  • Trustworthy data: Preserve HTTP, SSL, response-time, and incident history according to each plan.
  • Secure transport: Protect browser and API traffic with TLS and use scoped credentials for MCP and API access.
