About Monitoror

Monitoror is a wallboard monitoring application for displaying server status, CI build progress and other critical values on a shared screen. It is aimed at teams who want a simple, light-footprint dashboard they can put up on an office monitor without deploying a heavier monitoring stack.

The application is split into a Core HTTP API, configured through environment variables or a .env file, and a browser-based UI that renders the wallboard itself. It ships as a single-file Go binary runnable on 64-bit and ARM Linux, macOS, and 64-bit Windows, which keeps deployment simple.

Monitoror is released under the MIT license, with a live demo and documentation covering installation and configuration on the project's website. It is maintained by two named contributors and accepts donations and sponsorships to support ongoing development.
