README

Modern. Lightweight. Developer-first PHP framework.

Krystal Framework is designed for developers who want a clean, efficient, and productive environment without unnecessary complexity.

Why Krystal?

Extremely simple and intuitive API

Predictable naming, minimal boilerplate, and clear conventions let you focus on building features instead of fighting the framework.

Clean MVC architecture — done right

Straightforward controllers, views, and dynamic routing. No heavy ORM or ActiveRecord. Lightweight Data Mappers + Service objects encourage clean separation of concerns, testability, and maintainable code.

All essential tools included out of the box

  • Logging, caching, validation, form handling, pagination, flash messages, data mappers, SEO helpers.
  • Image processing (resize, crop, thumbnails, AVIF/WebP conversion, batch optimization)
  • And many other common tools — no need for dozens of third-party packages.

Built-in code generator

Quickly scaffold controllers, services, forms, migrations, admin CRUD interfaces, and more.

Minimal footprint

Small core size (~2 MB), fast boot time, very few dependencies. Performs well even in resource-constrained environments.

Clear and concise documentation

Straightforward examples, no overwhelming walls of text — easy to get started and productive quickly.

Who is Krystal for?

  • Developers who value simplicity and speed of development
  • Small to medium-sized projects, MVPs, internal tools, admin panels, and APIs
  • Teams that prefer explicit, maintainable code over heavy abstractions
  • Anyone building modern PHP applications (PHP 8.2+) without framework fatigue
