About Personal OS

Personal OS is a single home for the small systems that make up a life — notes, tasks, journals, finances, habits. Built as a modular monolith with PHP, MySQL, and vanilla JavaScript.

Principles

• Modular monolith. One codebase, clean boundaries between modules.
• Lightweight first. No frameworks until they earn their place.
• Documentation-first. Code that explains itself.
• Long-term. Built to be maintained for years, not chased every quarter.
