Ruby IDEs For Web Developers- Best In 2021

Ruby IDEs For Web Developers

Ruby on Rails is a server-side web development framework written using Ruby programming. It is an open-source web app framework and comes under the MIT license. Rails is a model view controller (MVC) framework.

It provides a default structure for a database, a web service, and web pages to the users. Rails also facilitate and encourage the use of various web standards. It facilitates the use of JSON or XML for data transfer and HTML, CSS, and JavaScript for web page display and user interface.

More about Ruby on Rails for web development:

Ruby on Rails is open-source software, so not only it is free to use, but users can also make changes to it to make it better. The main reason for the popularity of Rails for Web Development lies in the speed and ease of use that it provides to the developers.

It also allows users to quickly apply the changes made in the application. This avoids the time-consuming steps that are normally associated with web development. It runs easily on most of the Web Servers supporting CGI. The framework supports some popular servers such as MySQL, PostgreSQL, SQLite, SQL Server, DB2, and Oracle.

What is an IDE:

An Integrated Development Environment (IDE) is a software application used for programming in computers. IDE provides comprehensive facilities to programmers for the development of software. An IDE mainly consists of 3 different parts.

The first part is the source code editor that provides an editor for writing the codes from the program. The next section is the build automation tool that principally compiles the codes by the programmer. The third part is a debugger whose main job is to test or debug the program for any errors in the programming code. There are IDE’s available for several programming languages such as Java, Python, C, C++, and others too.

Nowadays most of the modern IDE has an intelligent code completion. The IDE design helps the programmer by maximizing productivity by providing tight-knit components. These components have a similar user interface that allows the programmer to easily use them.

Some IDEs contain either a compiler or an interpreter such as SharpDevelop and Lazarus. While some other IDE such as NetBeans and Eclipse contains both the compiler and interpreter for the execution of code. Some IDEs are primarily designed for a specific programming language.

However, there are many multiple-language IDE that allows users to do programming for multiple languages using just one IDE.

Basic Uses of an Integrated Development Environment:

The use of an IDE depends on the programming language. However, here are some of the basic uses of an IDE.

  • An IDE allows the programmer to instantly navigate to a type without getting worried about the project.
  • It also allows the programmer to easily navigate to other members by using them as hyperlinks.
  • It also allows programmers to automatically generate a code depending upon previous codes.
  • An IDE also organizes the different imports by the programmer and also adds some relevant imports.
  • It also gives warnings while the user is typing and some error occurs.
  • An IDE also keeps the view of files, errors, or warnings, and source code on the same screen that makes programmers work easy.
  • It also makes the running of unit tests easy as a programmer has to run the code from the same window.
  • IDE also allows the programmer to navigate directly to the compile-time error or run time exception directly from the error details.

Now, after knowing about the Ruby on Rails framework and IDE, let’s know about some of the best-known Integrated Development Environment (IDE) for the Ruby on Rails web application framework. So, here is a list of the Top 10 IDE for Rails.


RubyMine is a full-featured IDE for Ruby that includes most of the modern set of features that a user will need. These features will facilitate users with rapid web development. RubyMine comes from the house of the Jet Brains.
