I use exit1 to monitor my clients' websites and DNS, and it solves the issue of having to find out from clients that their website is down. This builds more trust with my clients and helps reduce website downtime since I can fix issues faster. I love the ease of use; it's simple to set up checks and alerts, and it's neatly categorized for easy management of all sites. Setting up a new check only takes 10 seconds, and enabling alerts via SMS and email is just a switch away. The initial setup was very easy, guiding me through the first check creation and straightforward after that. I also have it connected to Claude, using exit1's MCP solution for updates. Overall, I haven't found any shortcomings in the features I use daily.
