Simple to use, integrates with Laravel easily and has all of the features I require.

Excellent for website monitoring, not as easy to use for web apps with multiple services/domains/daemons/etc.

Oh Dear is one of those set-and-forget tools that you configure once, and then you hope to not be notified by them. Super reliable, love all those various checks that I can set up for my domains. It's not only site-is-down monitor, it's also cron, sitemaps, performance, lighthouse reports, status pages, etc. I love that I can give access to others as well, good for reports. Their support is also great, there were several occasions when I reported some bugs and they fixed them promptly, which is awesome. And the configuration is very easy - you add the domain, and depending on some features send them an HTTP request, and that's it. Super easy.

We switched from another provider because it became overly complicated to use and wasn't performing as we wanted. Plus costs were increasing that we couldn't justify. Oh Dear was refreshing because it just does what we want/need without unnecessary bloat. So often platforms constantly add features and functionality causing unwanted distractions as a customer. Oh Dear does the things we want whilst remaining simple to use and using up minimal time. We run a couple of accounts for multiple projects and have no reason to look elsewhere.

The overall experience with Oh Dear was ok, but I could not monitor a few domains because of them. One of my domains expired because they failed to notify me. I wanted to scale my account as I have many domains. Their support was there, but they never implemented a domain expiration date. Their website message is: "The TLD of your site isn't supported for the domain check. You can view the supported TLDs in our docs.". Their competitors can do what they can't. That made me jump ships. Now, ALL my domains are monitored.
