What is StackStorm?

StackStorm is an open-source event-driven automation platform for operational systems. It connects sensors, rules and actions so teams can respond to infrastructure events with repeatable workflows, integrations and controlled execution rather than manually repeating the same procedures.

The useful parts. The trade-offs.

Why consider it

Event rules make repeated operations consistent

Integration packs can reuse existing operational knowledge

What to keep in mind

Setup requires operations expertise

Poorly scoped actions can amplify configuration mistakes

How to use it well

Choose a well-understood operational event and connect it to a harmless diagnostic action first. Make the rule conditions explicit, record the expected output, and validate how the workflow behaves when an upstream system is unavailable.

Expand from diagnostics to changes only after ownership and rollback procedures are clear. Keep integration packs and credentials documented, and inspect execution history after deployments. StackStorm’s Apache license covers the automation platform, while connected infrastructure and any commercial services remain separate.
