## What it is
SSH2 client and server modules written in pure JavaScript for Node.js. It supports exec, shell, SFTP, port forwarding, and custom HTTP(S) agents without native dependencies.

## Use cases
- run remote commands over ssh from node.js
- transfer files via sftp in javascript
- implement an ssh server in node
- set up ssh port forwarding programmatically
- connect to servers with ssh using nodejs
- create an sftp-only server

## When to choose
- you need SSH or SFTP functionality in a Node.js application without native module dependencies
- you want to implement both SSH client and server behavior in JavaScript
- you need programmatic port forwarding, exec, or shell sessions over SSH

## When to avoid
- you need SSH tooling outside of Node.js
- you only need to run the ssh command-line tool rather than embed SSH in an app

## Facets
- artifact type: library
