Which file do I need?

• Windows: use the installer. Choose the portable .exe if you can't install software; it keeps no shortcuts, but your workspaces and settings are stored the same way.
• macOS: choose Apple Silicon for Macs with an M-series chip, or Intel for older Macs. Apple menu → About This Mac shows which one you have.
• Linux: the AppImage runs on most distributions without installing. Use the .deb on Ubuntu and Debian derivatives, or the .rpm on Fedora, RHEL and openSUSE, to get a menu entry.
• CI servers: use the testpion CLI instead of the desktop app.

Before you install

Code signing. The installers aren't code-signed yet. Windows SmartScreen may warn you the first time, and macOS asks you to confirm the first launch. The installation guides show exactly what to click.
