Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade kitty -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade kitty -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

- name: Install kitty
    name: kitty

Package Approved

This package was approved as a trusted package on 19 May 2024.


KiTTY is a fork of PuTTY (started from version 0.62 beta), the most popular Telnet and SSH client for Windows and Unix. It runs on Windows and it has an impressive collection of one of the most requested features that are missing from PuTTY.


Sessions filter, portability, predefined command shortcuts, session launcher, automatic log-on script, URL hyperlinks, automatic command and password, running locally saved scripts in remote sessions, ZModem integration, icons for each session, transparency, unfortunate keyboard input protection, roll-up, quick start of duplicate sessions, configuration box, automatic saving, Internet Explorer integration for SSH Handler, binary compression, clipboard printing, PuTTYCyg patch, background images/transparency, organizing sessions you save in a folder hierarchy and many others that are constantly added. You can find a complete list of its features on the main page - including a description for each one.

Package parameters

  • /Portable - Set kitty to use portable mode.

Example: choco install kitty --params "/Portable"


  • This package is know to have false positives on Virus Total for some of its executables which is no cause for concern. For more details see GitHub issue.

  • Package can not get updated or uninstalled if any of the kitty processes is running. For safety reasons you need to manually shut them down.

  • If the package is out of date please check Version History for the latest submitted version. If you have a question, please ask it in Chocolatey Community Package Discussions or raise an issue on the Chocolatey Community Packages Repository if you have problems with the package. Disqus comments will generally not be responded to.
