# Introduction

Sitealarm is a software service that lets you monitor your websites and web services. You can check the status of your website and see whether it's unreachable or returns an HTTP error code. You can also check whether specific keywords can (or can't) be found on the page you're monitoring.

For every site, you can also enable an SSL certificate check or monitoring for so-called mixed content.

On top of that, Sitealarm offers additional tools such as monitoring the health of your services or a heartbeat service.

List of features

  • Domain verification: Confirm that you own a domain β€” required for deep-crawl checks like broken links, mixed content, and sitemaps.
  • Uptime: As soon as one of your websites becomes unreachable, you get notified.
  • SSL certificates: We let you know when a certificate is about to expire or is invalid.
  • Mixed content detection: We crawl your websites and notify you when we detect mixed content.
  • Broken links: We crawl your website and notify you when we find a broken link.
  • Cron jobs: As soon as one of your scheduled tasks fails to check in with us, we send you a notification.
  • App health: We monitor important parts of your server and application. We let you know when disk space is running low, an API you rely on is unreachable, and much more...
  • Search: Find your monitors, heartbeats, and app health checks directly from the dashboard.

Each check is described in more detail on the pages linked above.
