Not available for Windows yet.
spec-kit doesn't publish an install command for Windows anywhere we can verify, so there's nothing for us to show you. We won't invent one. It does document one for macOS and Linux — switch to that tab.
Pastes into PowerShell and installs spec-kit on your Windows machine in one step. Runs as your normal user account, and needs no administrator rights.
Not available for macOS yet.
spec-kit doesn't publish an install command for macOS or Linux anywhere we can verify, so there's nothing for us to show you. We won't invent one.
Installs spec-kit in its own isolated environment, so it can't break the Python packages you already have. Runs as your normal user account, and needs no administrator rights.
What exactly does this do?
Open Terminal. On a Mac it's in Applications ▸ Utilities, or press Cmd+Space and type Terminal. On Linux, press Ctrl+Alt+T. Paste the command and press Enter.
Run spec-kit --help to see the available commands, and
spec-kit --version to confirm the install worked. If your shell complains about
permissions, that project usually documents a corrected command on its own site.
This installs spec-kit into its own isolated environment rather than into your system Python, which is why it won't break your other packages.

On mobile
spec-kit is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
spec-kit is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
