Docker Compose for Laravel + PostgreSQL + Mailpit
Laravel is the most popular PHP framework for web development, known for its elegant syntax and rich ecosystem. It is the framework of choice for SaaS products, REST APIs, and rapid application development with Eloquent ORM and first-class queue support.
PostgreSQL 15 is a powerful, ACID-compliant relational database with strong support for JSON, full-text search, and complex queries. Both Symfony (Doctrine) and Laravel (Eloquent) support PostgreSQL natively and it is increasingly preferred for new projects.
When should you use this stack?
Laravel with PostgreSQL is a solid default for local development when your production environment matches it. If you're evaluating alternatives, the related configurations below swap one piece at a time — same framework with a different database, or the same data layer under a different framework — so you can compare without starting from scratch.
