5 Best Ruby IDEs for Ruby on Rails Development in 2023


When it comes to picking the Ruby IDE, you have to be experimental. 

Because it’s a tedious task. There are numerous Ruby IDEs available, each offering something unique (that you will enjoy) as well as something you will dislike.

This causes you to get overwhelmed, and you grapple with the question, “Which Ruby on Rails IDE should I pick?”

The answer would be to try them all. It’s the most brilliant way of finding out which is superior for your Rails web development.

However, If you don’t know enough about IDEs, we’ve combined our thoughts on each one—the areas where they shine—everything from advantages to features—so you don’t have to brainstorm anymore when it comes to choosing the best Ruby IDE.

What is an IDE 

An IDE (integrated development environment) is a tool/environment in which a business takes its project idea from a concept to reality using its common functionalities, such as a source code editor, a debugger, and automated testing. For example, Eclipse, IntelliJ, NetBeans, Visual Studio, etc.

It’s hard to tell the difference between a code editor and an IDE, as they both have almost the same characteristics. 

A code editor lacks the heavy utility required to produce a high-quality product. However, using external plugins and features, it can be modified to serve as an IDE.

What is Ruby and Ruby on Rails

Ruby is the most elegant, expressive, and artistic programming language in the world. 

From the very beginning, it serves the sole purpose of elegance in building web applications and providing users with better readability. It makes use of Ruby on Rails API enabling web developers to deeply incorporate cutting-edge features and functionality into the websites they are building.

It’s a dynamically typed, object-oriented scripting language for building database-backed web applications. 

Ruby works in conjunction with its MVC framework, Ruby on Rails. In fact, Ruby on Rails is the one that brought popularity to Ruby with its exciting features like Gem, Rails migration, action controllers, metaprogramming, and more.

Ruby on Rails was made to help in managing data computation, internal logic, routines, and other tasks.

Popular tech giants such as Github, Airbnb, and Bloomberg use Ruby on Rails for their product development.

Why Develop Web Applications with Ruby on Rails

Ruby and Ruby on Rails perform exceptionally well in terms of creating web applications. It even surpasses its competitors like Python and Django, JavaScript, and Node JS in building efficient web solutions.

This is because they rely on their very philosophy of

  1. Convention over configuration– for lowering configuration hassles 
  2. DRY(don’t repeat yourself)– to code once and execute everywhere
  3. Active Record Pattern–  to create objects whose data need persistent storage

Here are some benefits of using Ruby on Rails.

Minimal Development Time

Ruby adheres to the principle of convention over configuration, which allows it to develop Rails applications at breakneck speed. 

The Ruby on Rails framework efficiently uses low code and Ruby’s object-oriented functionality, allowing you to create applications in a short period of time.

Effortless Testing

Ruby supports automated testing, which builds a testing skeleton while a developer is writing code, modules, controllers, and functionality.


Since there is a large talent pool of ROR developers on the planet, it is simple and reasonable to hire ROR developers from anywhere in the world.

Numerous Gems and Library Support 

The Ruby community is huge, and over the years it has provided tons of libraries and RubyGems. With such accessibility, programmers can create applications more quickly and efficiently without having to search for external resources.
