Build your GOV.UK service using the Ruby on Rails form builder

This library provides a form builder for the GOV.UK Design System. It makes creating forms easy and familiar for Ruby on Rails developers.

This guide provides a brief overview of how to install, configure and integrate the form builder with your project.

Every component of the form builder is designed to produce accessible HTML that meet all of the design system’s requirements without having to spend time reinventing the wheel.

This tool is aimed at developers. If you need a service that lets you build forms without writing any code, you can use one of the platforms that wrap this library like GOV.UK Forms or MoJ Forms.
