Open Nettest

Open Nettest

Open Nettest is a platform for measurement of the Internet connection over fixed, mobile or WiFi networks.

It places a strong focus on quality and reliability. Besides usual indicators like upload and download speed, Open Nettest performs unique measurements aimed to assess the quality of the connection and net neutrality.

Open Nettest provides a way to check your current connection speed and quality, not only in case of trouble, but at any moment and everywhere. Furthermore, Open Nettest enables a more extensive diagnostic test, including other parameters as signal strength, and quality in terms of network neutrality – e.g. blocked content, presence of middleboxes, etc.

It is an independent tool, improved with the expertise of Regulatory Authorities across Europe and the contributions of thousands of users and collected measurements.

The transparency of the methodology and the aggregation of the results, translated to statistics and offered as open data, always respecting privacy and anonymity of the data, makes Open Nettest a unique measurement platform for end users, operators, regulators and data analysts with the aim of improving the quality of Internet connection worldwide.


With wide support of devices and deployment scenarios, Open Nettest is a holistic measurement platform.

Open Nettest measures the connection from your device – the client device – and a measurement server. The client device and the measurement server will exchange data, letting us measure the quality of your Internet connection.

Open Nettest measurement platform

To support the measurements, the platform includes several measurement servers at different locations, control servers, databases and all the infrastructure to ensure a reliable service.

Mobile Apps

Open Nettest provides native applications for both iOS and Android. They are readily available from the respective app store on your smartphone or tablet.
