An SSH client, also known as Secure Shell client, is a software application that allows users to securely connect to remote servers or devices using the SSH protocol. SSH, which stands for Secure Shell, is a cryptographic network protocol that provides secure communication between two systems over an unsecured network.
SSH clients provide a secure way to access and manage remote servers or devices. They encrypt the communication between the client and the server, ensuring that sensitive information such as passwords or data is protected from eavesdropping or unauthorized access.
There are several use-cases for SSH clients. One common use is for remote server administration. System administrators can use SSH clients to securely access and manage servers, perform administrative tasks, and troubleshoot issues from a remote location. SSH clients also enable secure file transfers between local and remote systems, allowing users to securely copy files to or from a remote server.
The benefits of using an SSH client include enhanced security, as the SSH protocol provides strong encryption for data transmission and authentication. SSH clients also offer flexibility and convenience by enabling remote access to servers or devices from anywhere with an internet connection.

Additionally, SSH clients often support features such as key-based authentication, session multiplexing, and port forwarding, enhancing the usability and versatility of the client.
Overall, SSH clients play a crucial role in secure remote access and administration, providing a reliable and encrypted connection for managing remote systems and facilitating secure file transfers.
Here are the best open-source SSH clients:

filecxx4- Bastillion
Bastillion is a web-based SSH console that centrally manages administrative access to systems. It combines web-based administration with user's public SSH key management. Key management and administration are based on user profiles.
Administrators can login using two-factor authentication with Authy or Google Authenticator. They can manage their public SSH keys and connect to systems through a web-shell. Commands can be shared across shells to simplify patching and eliminate duplicate command execution.
Bastillion adds TLS/SSL on top of SSH and acts as a bastion host for administration. This ensures that infrastructure cannot be exposed through tunneling/port forwarding.
More details can be found in the whitepaper: Implementing a Trusted Third-Party System for Secure Shell. SSH key management is enabled by default to prevent unmanaged public keys and enforce best practices.

cyd019- SSB
Secure Shell Bruteforcer — A faster & simpler way to bruteforce SSH server.
pwnesia10- SSH-MITM
ssh man-in-the-middle (ssh-mitm) server for security audits supporting publickey authentication, session hijacking and file manipulation.
Password and publickey authentication are supported and SSH-MITM is able to detect, if a user is able to login with publickey authentication on the remote server. This allows SSH-MITM to accept the same key as the destination server. If publickey authentication is not possible, the authentication will fall back to password-authentication.
When publickey authentication is possible, a forwarded agent is needed to login to the remote server. In cases, when no agent was forwarded, SSH-MITM can redirect the session to a honeypot.
