Uptime testing for your website

Uptime testing for your website

Uptime monitoring is not only about getting information when your website is down. It's also about getting insights how your website perform from different locations in the world.

From the first second after your test is deployed you are protected against being unaware of the website downtime by getting notifications via e-mail or Slack.

After one hour you get performance insights from different places around the globe. We currently monitor your website from Europe, America, Asia and Australia.


Pricing is simple. Each check costs 0.00001€ (net).

It means uptime test set up for every minute costs around 0.44€ per month. For tests which is done every 10 minutes cost is less than 0.05€ a month.

Additionally you get free 0.50€ every month. You can spend it on whatever you want within the service. BTW, we do not charge you when your website is down since we call your website every 20 seconds during downtime.

Application monitoring (reversed uptime test)

Traditional uptime monitoring means our robots actively test given server or URL address against HTTP response (code and whether given keyword exists in the document body). Application monitoring uses an opposite manner. The application, worker or anything else sends a signal to our API.

You can configure how often this signal has to be sent to recognise the app working correctly. The most usual use case is sending a signal every time a CRON job finishes without an error.

If, for example, your CRON job should execute every day. You can configure the test so if there is no signal every 25 hours our system would consider this test as failing and trigger an alarm.


Configuration is very simple and will work in every environment that is able to send a HTTP POST request to api.agentslug.com. Please find more information about it on the application monitoring documentation page


Pricing is simple. Every hour of testing costs exactly 0.0014€ net. It means the maximum monthly cost is 1.04€.

We charge your account every hour which deducts from your pre-paid balance.
