updown.io vs Uptime Robot: What are the differences?

What is updown.io? HTTP monitoring solution with a clean UI and cheap and simple pricing. updown is an online service that checks your website's status by periodically sending an HTTP HEAD request to the URL of your choice. It then notifies you by email or sms when your website is not responding correctly.

What is Uptime Robot? Free website uptime monitor. Uptime Robot is all about helping you to keep your websites up. It monitors your websites every 5 minutes and alerts you if your sites are down.

updown.io and Uptime Robot belong to "Website Monitoring" category of the tech stack.

Some of the features offered by updown.io are:

• One-click sign in
• Fast checks
• Email/SMS alerts

On the other hand, Uptime Robot provides the following key features:

• http(s): that's perfect for website monitoring. The service regularly sends requests (which are the same as if a visitor is browsing your website) to the URL and decides if it is up or down depending on the HTTP statuses returned from the website (200-success, 404-not found, etc.)
• ping: this is good for monitoring a server. Ping (ICMP) requests are sent and up/down status is decided according to the "if responses are received or not". Ping is not a good fit for monitoring websites as a website (its IP) can respond to ping requests while it is down (which means that the site is down but the server hosting the site is up)
• keyword: checks if a keyword exists or not exists in a web page
