Cachet

Cachet is the open source, self-hosted status page system. It gives a team its own place to report incidents and service health rather than renting a hosted product for the job.

The current 3.x line is a rebuild of the original project, with the reasoning and the roadmap set out in a discussion on the repository. It is a PHP application, and the installation and upgrade guides live on a separate documentation site rather than in the repository itself.

Standing up an instance comes down to a short list of pieces.

• PHP 8.3: the minimum runtime, with later releases supported.
• Composer: dependencies install through it, as in any modern PHP project.
• Database: MariaDB, MySQL, PostgreSQL and SQLite are all supported.
• Documentation: installation and upgrade instructions are published on the project's own docs site.
• Demo: a public 3.x dashboard with shared test credentials, reset every thirty minutes.

The demo is the quickest way to click through the dashboard before installing anything, since its login details are printed in the README and the instance clears itself twice an hour. Security vulnerabilities go to the maintainers by email and are reviewed case by case. Cachet suits teams already running PHP that want the status page under their own control.
