A minimal, omni-conventional, declarative web framework for Crystal providing routing, views, and controllers.
Orion is a web framework for the Crystal programming language that provides routing, view rendering, and controller functionality. It solves the problem of building web applications by offering a flexible, declarative approach inspired by Ruby on Rails, allowing developers to create everything from simple APIs to complex web services.
Crystal developers building web applications who need a structured yet flexible framework for routing, views, and controllers.
Developers choose Orion for its minimal design, Rails-inspired conventions, and flexibility—it can handle simple use cases with just a few lines of code while scaling to support complex routing and authentication scenarios.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Inspired by Rails, it supports scopes, concerns, and constraints for complex routing, as shown in the README example with authenticated user constraints.
Ships with view rendering capabilities, supporting templating engines like Slim for dynamic content delivery without extra dependencies.
Uses a clean DSL for defining routes and controllers, allowing quick prototyping with just a few lines of code, as demonstrated in the simple example.
Includes direct static content delivery features, such as serving assets from directories, simplifying file management in web apps.
Relies on Crystal's niche community, which lacks the breadth of libraries, tools, and community support found in more popular languages like Ruby or JavaScript.
Focuses only on routing, views, and controllers, so developers must manually integrate components like ORM, authentication, or WebSockets, adding complexity.
While documentation exists via links, it may be less comprehensive or up-to-date compared to established frameworks, requiring more self-guided exploration.
