Web testing with Selenium

All browsers supported. Run tests on your local machine or using a cloud provider.

Mobile testing with Appium

Android and iOS. Run tests on a local device or using a cloud provider.

REST API testing

Built on top of the Apache HttpClient library.

Keyword-driven testing

Keywords are high-level building blocks which hide the complexity of the underlying technology and let you build concise, readable and maintainable tests. No coding skills required.

Parallel execution

Run multiple test sessions in parallel, limited only by the available hardware resources. When you've maxed out your local machine(s), spin up more test actors in the cloud(s).

Scripting support

JavaScript code can be embedded organically anywhere within your keyword-driven test to cover complex test scenarios.

Distributed testing

Write tests that execute seamlessly across multiple machines, networks and technologies. Write end-to-end tests that span mobile, web, APIs and anything in between.

Data-driven testing

Run a test multiple times, over a set of data records maintained in a separate data file.


Integrate with any technology by creating your own custom test actions (keywords).

Source control

Designed from the ground up to play well with Git and other source control systems. Perfect for large or geographically dispersed teams.


Build your tests once and run them against multiple environments or using different sets of test data.


Runs on macOS, Windows and Linux.
