Krystal Framework
=================

[](#krystal-framework)

**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?
------------

[](#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?
-------------------

[](#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
