Aptana Studio

One of the most popular open-source IDEs that helps to create dynamic and programmable web apps is Aptana Studio. With Rails, Aptana Studio offers integrated support. Due to its use of the external plugin RadRails, which has many high-tech features to make the development of database-driven web apps simpler, it is regarded as the greatest IDE for Rails.

The primary benefit of Aptana Studio is the automatic debugger. Another element that draws programmers to the product is the deployment wizard in Aptana Studio, which supports the protocols FTP, SFTP, FTPS, and Capistrano protocols. The outline view in Aptana Studio’s user interface is perfect for browsing classes by the names of their operations, and it is simple yet attractive.

Moreover, the IDE enables editing PHP, CSS3, JavaScript, and HTML5. It has a tonne of extensions, libraries, and interpreters and is completely free.


One of the most established and well-known IDEs among programmers is VIM. This is mostly for programmers who like to work exclusively with the keyboard for lightning-fast programming and dislike using a mouse. You may download free plugins for VIM that directly configure Ruby and Rails web development because it is an open source network that is versatile for programmers to use. Early on, it was discovered that a lot of Facebook developers were utilising VIM IDEs.

It is one of the most potent IDEs, supplying sturdy Ruby code that enables hosting development hosting. Text editor, file manager, preview, and many more capabilities are also included.

VS Code editor

Visual Studio is a popular choice for Ruby development among Rubyists. Simply install the vscode-ruby extension to get the language and debugging features for ruby. It makes use of Rspec and Cucumber for unit testing and debugging, Rubocop for formatting, and Rcodetools for autocompletion. Because it is a Microsoft open-source code editor, VSCode is free.

Sublime text

A complex text editor for code, markup, and prose is called Sublime Text. The incredible performance, remarkable features, and smooth user interface will win you over. Ruby is well supported by Sublime Text 3, which can be expanded with extra commands and text snippets to improve coding productivity. This is undoubtedly one of the most popular code editors right now, though recently users have started to choose other up-and-coming rivals.


When it comes to Ruby scripting and Rails web programming, Emacs is a total beauty and charming code editor. It is available for free usage and can be tweaked and personalised to meet needs. A dedicated Ruby plugin called improved Ruby mode for supporting Ruby programming exists since many Ruby developers use Emacs. Other Ruby-related packages include things like ruby-tools, rubocop-emacs, rake, rvm, chruby, bundler, and rbenv. Specifically, it is one of the greatest options when looking for a free Ruby IDE.


Ruby has a lightweight IDE called Arcadia. Also, it is entirely written in Ruby and utilises the traditional tcl/tk GUI toolkit. Arcadia includes a number of excellent capabilities, including support for executing, debugging, and editing scripts.

With user-friendly features like graphical debuggers and profilers, as well as a productive compiler and editor, NetBeans provides developers of all skill levels with a feature-rich platform. It offers fast entry points into build tools like Apache Ant and Maven and has the potential to interface with a number of version control systems. These integrated solutions enable software developers to complete projects faster while reducing their workload and expenses.

This IDE was developed by Oracle and is open source. Because it is a quicker and more intelligent way to code, it also appreciates the assistance of a sizable developer and programmer community. Let’s examine some of this code editor’s standout features for easier Ruby and Rails programming.
