I'd recommend working on editing any public-facing copy and unifying your message. I'm assuming I know what this tool does, but these examples do not validate that assumption. Is it a platform or a service? In 3 different locations, OpenStatus is listed as the "open source monitoring XYZ with...": "on-call managements", "Incident Management", and "beautiful status page".
Examples copied from the landing page and front page of the GH repo.
