parallel-ssh is an asynchronous parallel SSH client library for Python that can run commands and file transfers across hundreds to hundreds of thousands of servers concurrently. It uses native C-based clients (libssh2 via ssh2-python) for high performance with minimal client-side load.

Use cases

• run commands on many servers in parallel over ssh
• execute remote shell commands asynchronously from python
• bulk ssh automation across a fleet of hosts
• parallel sftp/scp file transfers to multiple servers
• automate remote server administration at scale
• non-blocking ssh client for python asyncio or gevent apps

When to choose

• you need to run ssh commands or file transfers on many hosts concurrently with high performance
• you want a python ssh library with native C bindings for low overhead
• you need async (asyncio or gevent) ssh client support

When to avoid

• you only need simple single-host ssh with no parallelism and prefer a pure-python library like paramiko
• you need an interactive ssh terminal session rather than programmatic command execution
• you need a ready-made orchestration tool rather than a library to build on
