St2
StackStorm is an event-driven automation platform that watches for events from external systems and triggers workflows, actions, and remediation across infrastructure tools. At its core, it provides a workflow orchestration engine that chains multiple actions and conditional logic into reusable, multi-step workflows for complex automation tasks, alongside a rules engine that applies matching criteria to triggers and maps trigger payload data to action inputs for automated responses.
The platform distinguishes itself through a ChatOps integration framework that enables executing commands and receiving notifications directly from chat platforms for team collaboration on operations, and an automation content as code system that stores rules, workflows, and actions in version-controlled packs for collaborative development and sharing. It also includes role-based access control to restrict user actions and resource visibility based on assigned roles, enforcing security policies across the automation environment.
The platform connects to diverse tools and services via sensors, webhooks, and actions to react to events across the infrastructure, and supports automated workflow triggering that fires a sequence of actions automatically when a predefined operational event occurs. It records a full historical trail of all action executions with triggering context and results for analysis, and persists key-value pairs for sharing state and configuration across automation components with optional encryption.
