Start your 14 days.
One copy and one paste starts a 14-day measurement of your own work. Then you get one answer: keep it, upgrade to an exact size, or buy less.
curl -fsSL https://sizemylaptop.com/install.sh | bash -s -- --startOpen Terminal (press Command and Space, type Terminal), paste, press Return. No password, no admin rights. Then work as usual: after 14 days it stops by itself, and baseline report opens your report in the browser.
Read it first
Download the script, read it, then run it.
curl -fsSLO https://sizemylaptop.com/install.sh && less install.sh && bash install.sh --startIf it asks for developer tools
The tool needs Python 3. A Mac without it shows Apple's one-time install window. Run xcode-select --install, wait for that window to finish, then paste the command again.
Nothing leaves your Mac unless you click Share or tick Statistics. It installs nothing else.
On Windows
Open PowerShell (press the Windows key, type PowerShell, press Enter), paste, press Enter. No administrator rights. Then run baseline start in a new PowerShell; it stops by itself after 14 days, and baseline report opens your report.
