Get notified when your site goes down, slow, or has an error.

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 businesses, non-profit organizations, or personal bloggers. Your website can go down for various reasons, including a database down or a hack.

Another common reason for a website to go 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.

However, if you are looking for an in-house solution, then you can try a PHP Server Monitor open source.
