“Why I don’t use Ruby on Rails?”

Ruby on Rails Performance Issues

Ruby on Rails is a powerful and popular web development tool, but it can sometimes suffer from performance issues that may cause headaches for developers. Despite the benefits of using Rails, such as its extensive library of helpful gems, low learning curve and high scalability potential, it is not always the best option for certain projects. Here are some of the reasons why you might not want to use Ruby on Rails.

Difficulty Debugging

When debugging issues in Rails applications, you often have to look through many layers of abstraction to find the root cause of a problem. This can be a time-consuming process and makes debugging complex applications difficult. Rails also uses a number of libraries and frameworks, which can be difficult to debug.

Memory Consumption

Rails applications often consume more memory than other popular web development frameworks. This can lead to slow performance and high server costs. If you are looking to build a resource-intensive application, Rails may not be the best choice.

Slow Development Speed

Rails is often criticized for being slow to develop compared to other frameworks. This is due to the fact that it relies heavily on conventions and “magic” to generate code. This can be a major issue for larger projects, as developers may spend hours trying to understand the inner workings of the code.

Lack of Flexibility

Rails is designed to make development easier and faster, but this comes at the cost of flexibility. Rails applications often need to be structured a certain way in order to work properly, and making changes to the underlying code may be difficult. This can be an obstacle for developers who need to build applications with complex features and functionality.

Does Netflix use Rails?

Yes, Netflix Uses Rails

Netflix is an online streaming service that delivers TV shows and movies to numerous devices worldwide. It is one of the most popular streaming services in the world and has a large user base. As a result, it’s important that Netflix provides a reliable user experience.

Why Netflix Uses Rails

Netflix uses the open-source web application framework Ruby on Rails to power its streaming platform. Ruby on Rails is a powerful, flexible tool that allows developers to quickly create web applications and websites. It is well-suited for complex sites that need to process a lot of data.

Ruby on Rails also offers a range of features that make it an attractive framework for large-scale applications. For example, it provides an “Active Record” feature, which allows developers to easily store and retrieve data from a database. Additionally, Rails provides a Model-View-Controller (MVC) architecture that simplifies the development process and helps ensure a consistent structure across all parts of the application.

Benefits of Using Ruby on Rails

Netflix has been able to use Ruby on Rails to create a reliable, secure platform for its users. The ability to quickly develop new features and functionality has allowed Netflix to quickly respond to customer needs. Additionally, Rails’ built-in security features have helped Netflix protect its users’ data.

Overall, Ruby on Rails has been an invaluable tool for Netflix and has helped the company remain successful in the competitive streaming market.

Why Ruby is better than Python?

Interpretability of Code

Ruby is known for its high interpretability, making it easier to read and comprehend written code. This makes it easier to pick up, even for beginners and those with no prior programming experience. In comparison, Python code is more verbose, making it harder to read and harder to understand.

Dynamic Typing

Ruby is a dynamically typed language, meaning that the data type of a variable or object is determined at runtime, rather than in advance. This makes Ruby code more flexible and easier to use. By contrast, Python is a statically typed language, meaning that the data type of a variable or object must be declared in advance.

Object-Oriented Programming

Ruby is strongly based on object-oriented programming (OOP), making it easy to create and manage objects. This is especially useful for creating web applications. Python also has OOP capabilities, but Ruby’s approach to OOP is more intuitive and easier to learn.

Developer Productivity

Ruby’s code is often shorter and less complex than Python’s, making development faster and more efficient. Ruby also has a number of built-in features that allow developers to create powerful applications with less effort. This makes Ruby a great choice for projects where speed and efficiency are needed.

What are the disadvantages of Ruby?

Unresponsive Support Community

One major disadvantage of Ruby is the unresponsive support community. Because Ruby is an open source language, developers don’t have access to official support from the creators. This means that any questions or issues developers face will be hard to resolve and may take a long time for anyone to answer them.

Difficult to Debug

Another disadvantage of Ruby is that it can be difficult to debug. The language has no built-in debugger, meaning that developers must rely on third-party tools or create their own debugging tools. This can significantly slow down development time and lead to more errors along the way.

High Memory Usage

Lastly, Ruby requires a lot of memory to run. This can lead to performance issues, especially if the application is running on limited hardware. This is especially problematic for applications that need to run on multiple platforms or need to scale quickly.

Which big companies use Ruby?

Big Companies Using Ruby

Ruby is an open-source programming language that is known for its simplicity, readability, and flexibility. It has been used by many large companies to build powerful applications and websites. Here are some of the most notable companies that have used Ruby for their projects:


Airbnb is one of the most popular and successful tech companies in the world. They were one of the first big companies to adopt Ruby as their primary language. Airbnb uses Ruby on Rails, a web application framework, to power their web application. They also use other libraries and frameworks such as React, Redux, and React Native to develop mobile applications.


GitHub is the world’s largest code hosting platform and a popular repository for open-source projects. It was developed using Ruby on Rails. The platform was designed to provide developers with an efficient and secure way to store, share, and collaborate on their code.
