winem/st2

This system is an enterprise-grade automation platform that orchestrates distributed workflows and event-driven actions across heterogeneous environments. It provides a unified interface to execute, monitor, and manage tasks on Linux, Windows, and remote hosts via SSH and WinRM. The platform supports complex, multi-step workflows with pause, resume, and retry capabilities, while also enabling real-time event streaming and automated rule enforcement.

How it got here

2014 · Modularization and packaging of core components

This period focused on restructuring the codebase into distinct, standalone Python packages (st2common, st2api, st2auth, st2reactor, st2actions) with dedicated build systems and entry points. It involved refactoring internal modules into modular, reusable components, introducing new models and utilities, and establishing a comprehensive test suite for each component.

95 changes

2015–2016 · Infrastructure and service modernization

This period focused on modernizing the StackStorm architecture by refactoring core components like content registration, logging, and action runners into modular, reusable packages. It introduced new services for streaming events and exporting execution data, while significantly expanding test coverage and CI/CD infrastructure to support these changes.

84 changes

2017–2020 · Runner and workflow engine integration

This period focused on integrating the Orquesta workflow engine and introducing new remote execution runners (WinRM, Inquirer) alongside significant refactoring of existing runners into modular Python packages. The work also established a metrics collection framework and a pluggable RBAC architecture to support these new capabilities.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 5 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 0e8ae756f3 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
