About ansible
Ansible is a radically simple, agentless IT automation platform, written in Python and licensed under GPL 3.0, that handles configuration management, application deployment, cloud provisioning, ad hoc task execution, network automation, and multi node orchestration for operators, developers, and network and cloud teams who manage machines over plain SSH.

About harmonist
harmonist is an MIT licensed, dependency free Python framework that adds multi agent orchestration and mechanically enforced protocol to AI coding assistants such as Cursor, Claude Code, Copilot, Windsurf, and Aider, and it serves individual developers and teams who need agent workflows to obey engineering rules rather than merely be asked to follow them.
