Runbook is an open source infrastructure monitoring service that allows you to perform automated "Reactions" when issues are detected. Runbook gives you the ability to automatically resolve DevOps alerts with zero human interaction.
Simply put, Runbook is what you would get if Nagios and IFTTT had a baby.
Runbook is primarily in maintenance mode, pull requests will be reviewed and merged but this project is not currently under active development. It is suggested that newer users check out Automatron as an alternative.
Runbook is 100% open source with our code repository hosted on GitHub. Runbook.io follows the OpenSaaS model, where Runbook itself is open source and easily deployable within Self-Hosted environments and Runbook Cloud is a subscription based SaaS offering. Runbook's code is licensed under the Apache 2.0 license which allows anyone to host their own instance of Runbook.

Runbook's SaaS platform is shutting down on 07/01/2016, existing users can still login to the dashboard to manage their account until that time.
