Safety
Where these links come from
Versions and download addresses are read automatically from winget (Windows) and Homebrew (macOS), the public package catalogues used by millions of developers. We only show a link when it points to the developer’s own official domain, and we never host, repackage or bundle the files — your browser downloads them directly from the developer.
Check the file after downloading (optional)
Compare the SHA-256 checksum shown above with the one of the file you downloaded. If they match, the file is exactly the one published by the developer.
- Windows: open PowerShell in your Downloads folder and run
Get-FileHash .\filename - Mac: open Terminal and run
shasum -a 256 ~/Downloads/filename
