PuTTYCM (formerly known as PuTTY Connection Manager) is a free and open source terminal emulator application. It is an enhanced version of the popular PuTTY SSH client, which is used to connect to remote servers over the Internet. PuTTYCM adds a tabbed interface to PuTTY, allowing users to open, manage and switch between multiple PuTTY sessions more easily. It also adds additional features such as session logging, text search, port forwarding, SSH key authentication, and more. PuTTYCM is a great tool for anyone who needs to access multiple remote servers and manage multiple PuTTY sessions at once.
Discontinued The project seems to be no longer developed. The latest version, 4.5.5.7, released in November 2015, can still be downloaded from the official website.
