Android, Windows, Linux GUI, and browser extensions are planned after their secure storage and platform threat models are accepted. There are no supported downloads for them yet.

Verified distribution

Use c6shq/tap/c6s-cli or https://c6s.whitekiwi.link/install.sh for macOS, and the Ubuntu installer linked in the CLI guide for Linux. The macOS CLI binary is checksum-verified and Developer ID-signed. Linux verifies publisher-signed checksums. The macOS CLI is not a notarized application bundle; the separately distributed macOS app is signed and notarized.
