Install Keon
keon is the command-line client for Kisenon — create and manage projects, branches, compute endpoints, and API keys without leaving your terminal. Pick the one-line installer for your shell, or grab a binary directly.
One-line install
If winget upgrade fails with “Unable to remove Portable package as it has been modified”, a keon update from 0.1.59 or earlier replaced the winget-installed binary. Run winget upgrade Seiraiyu.Keon --force once.
Direct downloads
The macOS binary is signed and notarized. After downloading, make it executable: chmod +x keon-macos-universal.
A browser download is quarantined by macOS. If Gatekeeper refuses to run it, clear the attribute: xattr -d com.apple.quarantine keon-macos-universal.
The notarization ticket cannot be attached to a bare executable, so the first Gatekeeper check needs network access to Apple. On a machine that is offline or blocks Apple’s notarization service, run the binary from a terminal — a shell launch is not subject to that check.
The Windows binary is not code-signed, so SmartScreen shows “Windows protected your PC” the first time you run it. Click More info, then Run anyway. Installing with winget install Seiraiyu.Keon avoids the prompt.
Downloads are pinned to v0.1.67 (the current release). Any published build is addressable at https://kisenon.com/dl/v<version>/<file>.
Verify your download
Each release publishes a manifest of SHA-256 digests. Compare the hash of your download against the value shown above (or in the manifest).
$ curl -fsSLO https://kisenon.com/dl/v0.1.67/keon-macos-universal $ shasum -a 256 keon-macos-universal $ curl -fsSL https://kisenon.com/dl/latest/manifest.json
On Windows, in PowerShell. The second line prints True when the hash matches the manifest.
