When it comes to web app development, there are many available options to choose from: Ruby on Rails (RoR), .NET, Node.js, Java, Python, and others. Thus, we compiled several articles where we help developers and startuppers to choose the right technology for their projects.

The next article in this series is Ruby on Rails vs .NET Core comparison. Let’s dive into the main features and characteristics of these frameworks and discover their pros and cons.

Ruby on Rails vs .NET Core — the basics

Ruby on Rails is an open-source Model View Controller framework written on Ruby for web application development and web-server integration.

It is based on the “don’t repeat yourself app development principle” which allows minimizing code repetition and the “convention over configuration” principle that presupposes the availability of the typical configuration settings that generally don’t require any updates.

.NET Core is a modular platform for software development created by Microsoft with an open-source code. It is compatible with Windows, Linux и macOS. It has a huge community on GitHub. .NET Core supports C#, Visual Basic .NET, and F#.

Open sourced and Enterprise

.NET is an enterprise solution that has many benefits. Being a mature framework it supports many languages and stacks which makes the development of the wide range of applications possible including cloud technologies. Thanks to JIT-compiled performance, .NET is fast and simplifies the creation of documentation.

Ruby is completely open-sourced, it means you can find most of the gems and plug-and-play solutions free and also easily create them. On the other hand, this framework often goes through multiple modifications and is unstable. Because of constant upgrades, the apps get constantly broken which complicates the developer’s tasks.

Ease of use

Visual Studio and additional modules make the development process a lot easier for those who like working on visual interfaces and need already written pieces of code to speed up the process. This makes .NET a perfect choice for those who want to create a robust application faster than it usually takes.

Ruby on Rails is easy to learn and use. Simple, flexible code as well as strong debugging features make the development process smooth.


Being a Microsoft framework, .NET has a huge community that also includes the .NET Foundation that fosters open development and cooperation within the .NET ecosystem. If you choose .NET you will be able to join the 60,000 developers and 3,700 companies already contributing to the .NET platform. You can also join the .NET community on Stack Overflow.

Ruby has even larger support than .NET, which means that there are a lot of developers who constantly contribute and make the framework better. It is done via the GitHub page where developers detect and submit issues and the Rails team fixes them respectively. RubyGems website counts more than 10,000 gems already. What’s more, you can find tons of tutorials where RoR developers share their knowledge and experience.

Ruby on Rails vs .NET — Performance and Scalability

.NET Core was created for enterprise projects, and it helps to lower the number of servers to save the cost of hosting and infrastructure. It helps easily scale programs horizontally and vertically to meet the business requirements. The framework has just-in-time compilation, native optimization, and caching services right out of the box.

Ruby has many frameworks, data-stores, and other additions that make it a good choice for scaling products.

- Redis. As Ruby supports caching out of the box you can use Redis as a cache to view fragment caching within your app’s code.

- Chef. Chef is a cloud infrastructure framework that helps to manage infrastructure dependencies, using less code and commands for system configuration updates, creating folder structures, and bootstrapping the whole system.

- Sidekiq. It’s a framework that can extend Rails’ capabilities of doing background jobs and queueing tasks.

What’s more, the latest version of Rails supports multiple databases, which means that now it’s much easier to add a database to your app if needed.

Companies that use Ruby

  • GitHub;
  • Airbnb;
  • Zendesk;
  • Hulu;
  • Shopify;
  • Dribble.

Companies that use .NET

  • Accenture;
  • Stack Overflow;
  • Starbucks;
  • Paralect;
  • Agoda.

Wrap up

All in all, both technologies are good choices for web development — one is for enterprise projects, another is for small projects. The success of your app depends on how wise your approach will be towards technology choice. From a development standpoint, both .NET Core and RoR are great technologies to build reliable products fast if you have proper talent onboard, and that might become a problem in both the short and long-term if you choose RoR. The RoR talent market shrank big time and it might be quite a bit of a challenge to quickly scale the team with proper talent when needed.
