The website’s availability is a critical part of a business; we can’t stare at the monitor all the time.

Setting up a command center and monitoring team is feasible for a large organization to monitor their web applications uptime but not for small-medium business, a non-profit organization, or personal blogger. Your website can go down for various reasons, including database down or hack.

Another common reason for website down can be a hosting provider, and that’s why you should always host your site with a reliable hosting provider. Any website owner or administrator needs to ensure proper alerting is in place, so you get notified when the website is not available.

I’ve listed the following tools, which will help you get notified in case your web URL goes down. Most of them offer a FREE plan, so pick the one you like.
