I use Better Stack for monitoring my website's downtimes at https://xocat.online. I like how it's free and easy to use. The tool that helps me monitor my website's downtimes is the most valuable to me because it lets me know if something's wrong with my website. Additionally, I find it particularly valuable that when my website is down, my users can simply go to https://status.xocat.online to check if something is down. The initial setup was extremely easy; all I had to do was add the DNS records and my domain, and status.xocat.online was up and running.

Reliability of warning systems. Always received email as expected

The free tier covers all my needs, even if I scale in the future. The UI is nice and polished. If I ever increase the number of domains I manage, I’d definitely consider a paid plan. For now, though, it’s more than just a “try it and see if you like it” situation—the free tier genuinely feels complete. Overall, it pretty much covers everything I’d need in a domain monitoring SaaS.
