8 Top Free and Open Source Crystal Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.

A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.

Crystal is a general-purpose, concurrent, multi-paradigm, object-oriented programming language. With syntax heavily inspired by the language Ruby, it is a compiled language with built-in static type-checking, but specifying the types of variables or method arguments is generally unneeded. This adds the benefit of a shallower learning curve.

Here’s our recommended free and open source web frameworks for Crystal captured in a legendary LinuxLinks’ chart. Only free and open source software is eligible for inclusion here.
