Why HD CMS Runs on Supabase

When I built HD CMS, I needed a backend that could handle everything — content storage, user authentication, file uploads, real-time updates, booking management, and payment tracking — without the complexity of managing separate services.

Supabase is a managed PostgreSQL platform that wraps a production-grade database with authentication, file storage, real-time subscriptions, and row-level security. It's open-source, built on proven technology, and has no vendor lock-in.

Every HD CMS site runs on Supabase. Your content, your bookings, your customer data, your images — all stored securely in a PostgreSQL database with enterprise-grade security policies.

WordPress uses MySQL with no row-level security. Every plugin has full database access. A vulnerability in one plugin can expose your entire database — and every other site on the same shared hosting server.

HD CMS uses PostgreSQL with row-level security policies on every table. Each site's data is isolated at the database level. Even if a query somehow bypassed the application layer, the database itself enforces access control.

This isn't theoretical security. It's the same approach used by financial services and healthcare applications. Applied to a CMS, it means your client data, booking information, and content are protected by the database engine itself — not just by application code.
