Desktop app

Download Assertline for Windows or Mac

The desktop app runs your tests in the background on your own computer, on a schedule if you want one, lets you create tests with AI in a browser you can watch, and opens the dashboard in its own window. It is part of every plan, Free included.

Windows

For Windows 10 and Windows 11, 64-bit.

Download for Windows

85 MB. Windows asks you to confirm the first time: choose More info, then Run anyway.

Mac

For macOS 11 (Big Sur) or later.

Apple chip (M1 or later) Intel chip

Signed and notarized with Apple. Which Mac do I have?

Install on Windows

  1. Open the file you downloaded.
  2. Windows shows a blue “Windows protected your PC” box. Choose More info, then Run anyway.
  3. Assertline installs for your user account and opens. Sign in: your browser opens for the sign-in and hands you back to the app.

Why the blue box: the Windows version is new and not yet signed with a Windows certificate, which is on its way. A work computer may not allow the install until then.

The Windows version does not update itself yet. Come back to this page for newer versions.

Install on Mac

  1. Open the file you downloaded.
  2. Drag Assertline into the Applications folder.
  3. Open Assertline and sign in. Your browser opens for the sign-in and hands you back to the app.

The Mac version updates itself: you get a notice, and the new version installs the next time you quit the app.

Which Mac do I have?

Open the Apple menu and choose About This Mac. A line that starts with Chip and names an Apple M chip means Apple chip. A line that starts with Processor and names Intel means Intel chip.

Already installed? Open the desktop app. The first start downloads the browser the app runs tests in, so it needs an internet connection and a minute or two.

There is no version for Linux yet. On any system you can run tests in your own browser or on our cloud from the dashboard.
