In their own words
Fabric
Fabric is a free, open-source Python library for running shell commands remotely over SSH and returning Python objects. It supports individual hosts and multiple hosts, with serial or parallel execution, and can run Python functions or code blocks against those connections. Through Invoke, Fabric exposes Python tasks with parameters and pre- or post-tasks through the fab command-line tool; a comma-separated host list supports serial task execution. Paramiko supplies SSH protocol support, while documented authentication methods include private key files, SSH agents, and passwords. The installation guide recommends pip install fabric and lists Python, Invoke, and Paramiko as requirements. Fabric is available for Linux, macOS, and Windows in a self-hosted, agentless model. Its documentation says it adds no extra GSSAPI support beyond Paramiko’s connection parameters. Modern Fabric can be installed alongside Fabric 1 for a gradual upgrade. Each run or sudo call uses a separate remote shell session, so directory changes do not persist between calls.
Salt
Salt is a free, open-source framework for remote execution, configuration management, provisioning and infrastructure orchestration. A single execution can run commands across thousands of systems in seconds. A typical setup has a master managing minions, but Salt also supports agentless operation through salt-ssh or salt-proxy and stand-alone use. Salt states define configurations that can be extended and layered, while orchestration can order work by dependency, such as preparing a load balancer before a web-server cluster. Salt Cloud provisions systems on cloud hosts and hypervisors and can connect new virtual machines to a master. Its documented providers include Amazon EC2, Google Compute Engine, Azure, OpenStack, DigitalOcean, Linode, VMware and Proxmox. SaltStack Config adds a web interface, role-based access control, multi-master support, reporting and an enterprise API, along with LDAP, SAML, OIDC and Active Directory integrations. Salt uses RSA key authentication and encrypted master-minion communication. It is self-hosted and licensed under Apache 2.0.
