What Big Sister is
Big Sister is monitoring software for Linux, Windows, and the web. It performs synthetic checks to monitor whether services respond as expected and tracks traffic activity. Email is the listed alert channel, so notifications can be sent when monitored conditions need attention. Big Sister uses a self-hosted deployment model, allowing the software to run in the organization’s own environment rather than as a hosted service. Its listed pricing model is free, and a free plan is available. The monitoring scope includes synthetic checks and traffic monitoring, but topology maps are not included. The combination suits organizations that want basic service and traffic oversight across several platforms, with email notifications and control over deployment. Users should account for the self-hosted setup and the absence of topology-map views when deciding whether its monitoring coverage matches their environment.

Big Sister suits organizations needing free monitoring on Linux, Windows, or the web. It is intended for teams comfortable with self-hosted deployment and email alerts.
