v2026.10.24.1

New here? Download the one for your computer and install it. Its first start downloads Python and the app (about 330 MB), which takes a few minutes, then it opens in its own window.

• Windows: AlphaHarness-windows-x64-setup.exe. Windows warns that it does not recognise the app — it is unsigned. Choose More info, then Run anyway.
• Mac: AlphaHarness-macOS-arm64.dmg for Apple Silicon (M1 or later), or AlphaHarness-macOS-x86_64.dmg for Intel. Open it and drag AlphaHarness into Applications (if it asks, replace the old one). The first time, macOS will not open it because it is unsigned: open System Settings › Privacy & Security, scroll down, and choose Open Anyway.
• Linux: AlphaHarness-linux-amd64.deb, for Ubuntu 24.04 or later. Open it to install, or run sudo apt install ./AlphaHarness-linux-amd64.deb.

Closing the window keeps Alpha Harness in the tray (the menu bar on a Mac), so your tasks keep simulating. To stop it, choose Quit Alpha Harness there.

Already have it? Alpha Harness offers this version in the app. If it also asks you to install the new desktop app, quit the one you have, then install the one above: your data, Alphas and sign-in all carry over.
