Quick Verdict
Choose MySQL if you need a proven, standalone relational database for traditional web applications. Choose Supabase if you want a complete, integrated backend-as-a-service with real-time features and instant APIs built on PostgreSQL.
MySQL is a mature, standalone relational database management system (RDBMS) focused on reliable data storage and transaction processing. Supabase is an open-source backend platform that bundles a full-featured PostgreSQL database with authentication, real-time subscriptions, and auto-generated APIs. While MySQL is purely a database server, Supabase offers a more integrated, developer-friendly suite of tools, albeit with a managed service cost. Their core difference lies in approach: MySQL provides a single, foundational component, whereas Supabase provides an entire backend ecosystem.
