Tutorials Point Scala Compiler

I first discovered Tutorials Point when I was learning how to program. Tutorials Point offers tutorials on web development languages and other programming subjects, including an editor and compiler for each tutorial. The site’s Scala tutorials let you learn Scala as you write your programs in it.

Visit https://www.tutorialspoint.com/compile_scala_online.php to use Tutorials Point’s Scala compiler.


OneCompiler is another free online Scala compiler. Although they are not dedicated to compiling Scala programs, the platform incorporated a Scala compiler interface when the programming language became trendy.

You can visit https://onecompiler.com/scala to use OneCompiler for your Scala adventures.


Paiza.io is a Japanese outfit that provides a minimalist platform for the compilation of 20+ popular programming languages. I was surprised to find Scala on its list of compilable languages.

You can visit https://paiza.io/en/languages/scala to start coding and compiling Scala on Paiza.io. To save your codes and share them, you will need to sign up on the platform. It is free.


Ideone is an online compiler and debugging tool which allows you to compile source code, execute it online in more than 60 programming languages, and even share your code with others.

While I was looking into some of the best Scala online compilers, I found that the platform allows Scala programming. To use Ideone Scala online compiler, log on to https://ideone.com/l/scala.

Microsoft Visual Studio

Everyone knows Microsoft’s Visual Studio. Even if you just started programming recently, you must have come across Visual Studio. Well, Microsoft’s Visual Studio is a software development environment used to create applications including websites, web apps, web services, and mobile apps.

You can use it to code Scala. Geeks for Geeks has a comprehensive resource on how to install Scala with VSCode.

Sublime Text

Sublime Text is a source code editor that natively supports many programming languages and markup languages. Users can expand its functionality with plugins, which are typically community-built and maintained under free-software licenses. It is most commonly used by C++ and Python programmers but if you are looking for a cool platform for Scala, you can use it.


BlueJ is an integrated development environment for the Java programming language. It’s designed for educational purposes, but it can also be used for small-scale software development. Although it runs with the help of the Java Development Kit, BlueJ can be used to code Scala too.

GNU Emacs

GNU Emacs is a text editor produced by the GNU Project. It was created by Richard Stallman, who based it on the original Emacs editor which was developed for Unix operating systems. You can use it to code and compile Scala.

Atom Text Editor

 Scala Compilers

Designed by Github, Atom Text Editor is an open-source text editor that can be used as an IDE for a huge array of programming languages.

You use the Atom IDE for Scala via https://atom.io/packages/ide-scala.


 Scala Compilers

As we began to learn Java programming in college, we were introduced to NetBeans, an IDE (integrated development environment) that is specially designed for Java. It’s expected that Scala will be able to run on NetBeans as well because of the close similarity between the two languages. You will need a plugin to use Scala on NetBeans.


 Scala Compilers

Vim is a text editor built for efficiency when creating or changing any kind of text. It’s free, open-source, and can be used to code and compile Scala. If you want a superfast compiler for Scala, try Vim.

IntelliJ IDEA

 Scala Compilers

IntelliJ IDEA is a Java-based integrated development environment (IDE) for developing software in the Java and Kotlin programming languages. It also supports other JVM-based languages, including Groovy. You can use it to compile Scala but it is not free.

Spacemacs Text Editor

 Scala Compilers

Spacemacs is a unique text editor. It is a user-friendly configuration framework for GNU Emacs that enables you to take advantage of all of GNU Emacs’ features, including both graphical and command-line interfaces, as well as being executable under X Window System and within a Unix shell terminal. In all, you can use this to compile Scala as well.


We hope the 15 sites in this article will be of use to any Scala developers who are looking for a convenient way to test out their code without having to run Scala locally. There are many more sites available, and as technology advances, this list will likely grow. As a Scala developer myself, I try to find new resources for testing code using online compilers whenever I have time. I know how frustrating it can be having to go back and forth between running your code locally and testing it on an online compiler.
