StackStorm

StackStorm connects event sources - monitoring alerts, webhooks, sensors, schedules - to automated actions and workflows, acting as a programmable "if this happens, do that" layer for IT operations. Its rule engine lets teams codify remediation and operational runbooks so routine incidents are handled automatically instead of manually.

StackStorm is a fit for operations teams that want to automate reactive, event-triggered tasks - auto-remediation, alert-driven runbooks, ChatOps - a different niche from Temporal or Argo Workflows (also in this catalog), which orchestrate explicitly-invoked application workflows rather than reacting to external events.
