StackStorm

StackStorm is open source event-driven automation for DevOps and IT operations teams. It works as a glue layer that listens for events from monitoring systems, chatops, CI/CD pipelines, or any webhook source, then runs remediation, deployment, or incident response workflows. Think of it as IFTTT for sysadmins with real enterprise teeth.

StackStorm integrates with tools like Nagios, Sensu, Datadog, PagerDuty, Slack, GitHub, and many more through a plugin system called packs. It runs on Linux (CentOS, Ubuntu, RHEL) and can deploy on Kubernetes or bare metal. The project uses a sensor and action runner architecture that supports Python, shell scripts, Ansible, and even PowerShell. Its rules engine evaluates conditions in real time to decide what actions to fire.

StackStorm is free and open source under the Apache 2.0 license, maintained by the StackStorm team and a community of contributors. It is ideal for teams that want to automate repetitive ops tasks and build complex, cross-tool runbooks without locking into a proprietary vendor. The project has been adopted by companies like Walmart and Salesforce for large-scale infrastructure automation.
