MVC Conventions

Instead of having to plan where things go, Amber comes with a set of conventions to guide you in developing your application.

Build Secure Apps

Built-in tools for input validation, CSRF protection, Form tampering protection, SQL injection prevention, and XSS prevention, helping you keep your application safe and secure.

A beautiful Type Safe Language

Crystal inspired by Ruby is a statically type checked, so any type errors will be caught early by the compiler rather than fail on runtime. Crystal uses green threads, called fibers, to achieve concurrency.

The Right Amount of Tooling

The things you need are built-in. CLI, Translations, database access, caching, validation, authentication, including tools for deployments secrets encryption.
