Testomato is an online service for monitoring websites. It regularly checks that your pages are available and that they show what they should, and it alerts you when something goes wrong, so you can fix a problem before your visitors or customers run into it.

What it does

A website can fail in many ways. The server may stop responding, a deploy may break a page, a database error may replace the content with a blank page, or an important part of a page, such as a price, a form or a login box, may quietly disappear. Testomato checks the pages you choose at regular intervals and watches for exactly these kinds of problems.

Typical checks include:

• Availability – whether the page responds at all.
• HTTP status – whether the server returns the expected status code, and not an error such as 404 or 500.
• Content – whether the page contains, or does not contain, a specific text. For example, it can confirm that a product page still shows the price, or that an error message never appears.

When a check fails, Testomato sends a notification, so you learn about the outage from the monitoring and not from an angry customer.

Who it is for

• Website and e-shop owners who need to know right away when their site is down.
• Web developers and agencies who look after many client websites and need to see at a glance which ones have a problem.
• Teams that deploy often and want to catch a broken page right after a release.

Uptime vs. content monitoring

Many monitoring tools only ask, "Does the server respond?" That is useful, but a page can respond perfectly well and still be broken: it can return a status of 200 and show an empty template, a maintenance notice or a database error.

Checking the content of the page closes this gap. If you tell the monitoring what a healthy page looks like, for example, "the homepage contains the shop name and the search box", it can raise an alert when the page is technically up but practically useless.

Getting started

1. Sign up on the Testomato website.
2. Add the URLs you want to monitor, starting with the homepage and the most important pages: checkout, contact form, login.
3. For each page, add the text that must be present and, optionally, the text that must never appear.
4. Set who should receive the alerts.

It is good practice to start with a few key pages and add more over time, rather than monitoring everything at once and drowning in alerts.
