Our uptime check can now verify the absence of a string

The most popular check that Oh Dear offers is, without a doubt, our uptime check. It's enabled for almost every site we monitor.

By default, this check will notify you when your site returns a non-2xx response, but you can greatly customize that behavior.

You can check if the response has certain headers, if the response contains a particular string, and more!

Some of our users requested a new behavior: checking the absence of a string on the response. We're happy to share that we've now added that feature.

This way, you can ensure that a string like "An error occurred" does not appear on your page. As soon as it does, we'll send you a notification.

We hope you like this little improvement. Should you have any ideas or feature requests to improve Oh Dear, let us know!
