PSR-based runtime
HTTP messages, middleware, factories, logging, HTTP client integration and the DI container follow PSR contracts where it makes sense.
Lemonade Framework
Modular application framework for PHP 8.1+.
Explicit architecture for websites, administration systems, CMS projects and integration applications. Lemonade is built on a PSR runtime, DI container, providers, routing and CLI. It adds infrastructure for databases, migrations, cache, localization, validation, queues, APIs and security.

What ships with Lemonade
Core capabilities

Modular application infrastructure
Databases and migrations, cache, localization, validation, queues, APIs, middleware, security, uploads, events and support utilities are organized as explicit framework modules.
