# fab-classic — fab-classic is a simple, Pythonic tool for remote execution and deployment.

License: permissive · Maintenance: active · Downloads: 124.1K/mo

## What it is and what it does

fab-classic is a Python library and command-line tool for executing remote shell commands and transferring files over SSH, designed for deployment and systems administration. It is a maintained fork of Fabric 1.14 with Python 3 compatibility patches, intended for projects already using Fabric 1.x that do not want to migrate to breaking changes in later versions. The package wraps paramiko at a higher level, providing a simpler Pythonic interface for common SSH tasks.

You define tasks as Python functions and execute them on remote hosts using the fab command-line tool, or import components into other Python code. It supports local and remote command execution, sudo operations, file upload/download, and user prompting. The package depends on paramiko for SSH protocol support and is actively maintained with recent commits.

Use it for:

- Deploy applications to multiple servers by defining deployment tasks and running them with the fab tool.
- Execute system administration commands across a fleet of machines as part of operational workflows.
- Automate file uploads and downloads between local and remote systems during deployments.
- Migrate legacy Fabric 1.x codebases to Python 3 without rewriting for incompatible API changes.
- Build custom deployment scripts in Python that need to run shell commands on remote hosts over SSH.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

fab-classic provides SSH-based remote command execution and file transfer for deployment and systems administration tasks, built on paramiko.

Yes, if you are maintaining a Fabric 1.x codebase and need Python 3 support without migrating to later versions. The package is actively maintained, has low install friction, carries no known vulnerabilities, and uses a permissive license. Be aware that it requires careful dependency management around paramiko versions. Not recommended for new projects.

## Install

pip install fab-classic
uv add fab-classic
poetry add fab-classic

## Installing fab-classic

Before you install: Low install friction with a pure-Python wheel. Maintenance is active with recent commits. Note: version 1.21 switched to the original paramiko dependency; if you have an older variant installed, uninstall it first to avoid import conflicts, or set PARAMIKO_REPLACE=1 during install to use an alternative instead.

License in practice: Licensed under BSD (permissive), allowing use in most commercial and open-source projects without significant restrictions.

Quickstart:

pip install fab-classic

from fabric.api import run

def host_type():
    run('uname -s')

# Then run: fab -H localhost host_type

Requires Python 3.5 or later. If you have an existing paramiko variant installed, uninstall it first to avoid import name conflicts.

Verify before relying:

- Whether the package's bug-fix-only maintenance model is sufficient for your deployment use case over time.
- Performance characteristics for large-scale deployments.
- Compatibility with current versions of paramiko beyond what the fact sheet documents.
