Different use cases, ours is for people who prefer simplicity and just want a text to know if their server goes down. We charge $5 for the year, this service charges $108 (But is aimed at larger enterprises and provides more analytics like monitoring logs/custom status pages). I'm sure their service is great for their enterprise customers, but for smaller teams I feel a text when your server goes down solves the key pain point.
