UptimeRobot

UptimeRobot is a tool that monitors your website’s uptime and sends you alerts when your site is down.

Know when your website is down with Uptime Robot. The tool will check your website in one-minute intervals and notify you immediately when the site is down. The monitor does multi-location checks from various geo-locations to prevent false positives.

Get instant alerts for downtime on the platform of your choice. You can get alerts via email, SMS, voice call, Slack, Twitter, or other apps. You can even set recurring notifications so that you don’t miss an outage.

Doing maintenance on your site? No problem. Just set up maintenance windows to pause monitoring during planned maintenance periods.

With the mobile app, you can get instant alerts, manage monitors, and check your uptime statistics on-the-go. The app is available on both Google Play and the Apple App Store.

Be transparent about your uptime by sharing it with others on the public status page. You can also inform customers about both planned and unplanned outages.

UptimeRobot also offers SSL monitoring that alerts you to any SSL certificate errors. Set this up within the main HTTPS monitoring of your site, and you’ll automatically get alerts when there’s an error.

Stay on top of SSL certificate renewal with expiry notifications. UptimeRobot will send one 30, 14, 7 and 1 day(s) before expiration so that you have time to renew and maintain site security.

With cron job monitoring, you’ll get instant alerts when a cron job fails or never starts. This type of monitoring is ideal for those who want to know whether their devices are connected to the Internet regularly.

You can also setup monitors for whether a keyword is or is not included in the HTML page code. This can help you monitor when a product is back in stock on a page.

Port monitoring allows you to monitor any specific port on your server to make sure databases and other services on the port are still available. Monitor your DNS port to ensure your DNS connection works, or monitor your POP3, IMAP, or SMTP port to be alerted to issues with your email service.

UptimeRobot also allows you to monitor server availability by pinging your publicly available server. You can also monitor devices and server response time.
