Developer experience (DX) tools are critical in boosting your team’s productivity, innovation, and satisfaction. With the right tools, your developers can write great code faster, collaborate better, and automate some of the more repetitive mundane tasks.
Being software engineering consultants we have a unique perspective on how different developer experience tools work with our client’s tech stacks. We have gathered a collective experience of our engineers and prepared this list of 9 developer experience tools that our clients and their developers found helpful.
The list is in no particular order, as there's no way to name one tool as significantly better than another; it's all about which tool is better for a specific project. However, from point five onwards, we are focusing on tools for projects powered by the Scala programming language.
The selection of tools we present is designed to improve the Developer Experience (DX) of your team. While DX might initially seem abstract, merely connected to job satisfaction, there are tangible business reasons behind it.
Enhancing your team's DX allows your developers to operate in a streamlined environment without unnecessary complications. They can then focus on writing code, solving real-world problems, and achieving their objectives more quickly.

Scala CLI simplifies compiling, running, and packaging Scala code, making it an essential tool for Scala developers. It’s a command line-focused tool that tries to bring the simplicity of interpreters together with some more advanced features, which you would normally only find in a larger build tool.
Scala CLI is now the default runner for Scala 3, and it is distributed together with its artifacts. It is also included in the language installation by default, so if your team has Scala installed, they have Scala CLI as well.
Why Scala CLI is one of our recommended Developer Experience tools?
We recommend Scala CLI for scripting and prototyping projects, partially thanks to Scala Toolkit initiative that promotes a set of simple libraries for rapid prototyping. It has other advantages as well.
- Support for Scala.js, Scala Native, Graal’s Native Image, and JVM, as well as IDEs such as Metals and IntelliJ.
- Quick switching between Scala and Java versions.
- Easy tool configuration directly in the source files.
Our engineers also highlight Scala CLI’s ability to manage and automatically download all of the required library dependencies, as well as the necessary JDK/JVM versions and other tools.
Scala CLI can run any Scala class or script, replacing the need for build tools such as sbt in smaller projects. Configuration can be directly embedded within the input source files through functional code comments known as using directives, which are placed at the beginning of the file. For example, comment //> using scala 3.5.2 specifies the Scala version to be used.
Metals is a lightweight language server for Scala. It offers robust IDE features without the weight and complexity of a full IDE. It allows for more advanced features such as refactorings, debugging, or worksheets.
Why Metals is one of our favorites?
Language servers such as Metals follow the Microsoft LSP specification and it allows them to be connected to any editor that supports the same protocol without the need for a dedicated plugin.
- It’s compatible with multiple editors, including online ones.
- It has most of the IDE features without being one.
- It enhances productivity while being fast and lightweight.
- It supports all the new Scala 3 features.
Metals has the best support for the features in the latest versions of Scala. It can identify and display the same errors that the Scala compiler would find during the process of compiling the code.
Metals has also a rich community of users with maintainers being able to quickly and efficiently fix any potential bugs.
Scalafix is a tool for Scala developers looking to enforce a consistent code style and migrate between Scala versions. It allows users to verify chosen rules in continuous integration and IDEs.
Why Scalafix is a great Developer Experience tool to use in 2025?
Our engineers have named four reasons why Scalafix is an excellent developer experience tool for our clients' projects.
- It detects and fixes common code issues using a rich suite of rules.
- Facilitates seamless version migrations between library and Scala versions.
- User can create their own rules to lint or rewrite their code.
- It can be run from most of the existing Scala tools, such as sbt, mill, and soon, Scala CLI.
Scalafmt keeps your codebase clean and consistent. By automating code formatting, it ensures that every team member follows the same style guidelines. It has a large number of configuration options so that it can fit your formatting tastes.
Why do we recommend Scalafmt?
Scalafmt has many advantages, but there are three in particular that make it a good developer experience tool.
- It’s integrated into most of the existing tools including Scala CLI.
- Easy configuration for team-wide consistency.
- It reduces code review friction.
Our engineers have named three other Developer Experience tools that show promise or possess features that our engineers appreciate. Watch out for these tools, as they may become your new favorites in 2025.
WartRemover
WartRemover is a flexible linter for safer Scala code. You can use it to write your own rules that help you improve your company’s codebase. Also, it lets you choose some of the existing and well-tested rules. WartRemover helps prevent common coding errors, reducing the reliance on manual code reviews.
To use WartRemover, simply add it as an sbt plugin or as a compiler plugin with your tools. We recommend integrating it into your workflow for cleaner, safer code.
Mdoc: Documentation for the modern developer
Mdoc simplifies the creation and maintenance of technical documentation by evaluating embedded Scala code examples within markdown files. It integrates with other tools to create web pages for your projects.
It's a great developer experience tool if you want to ensure that your examples always work, enabling your users and junior developers to easily find correct examples.
Bloop: Fast build server for Scala
Bloop is a build server for Scala and Java programming languages. It provides other tools with the ability to efficiently compile code via Build Server Protocol, which enables it to integrate with both Metals and IntelliJ. Our engineers recommend Bloop’s for Scala projects as it delivers on its flagship features.
- It keeps the compiler optimized by reusing it between compilations.
- Integrates with most of the existing Scala tools.
- Allows multiple projects and modules to be compiled at the same time.
The other advantage of Bloop is that it can also be used from the command line, which will reuse any previously compiled artifacts for a project even if it was done previously by IDE.
It is the only developer experience tool on our list that is mostly used internally by other build tools. Previously mentioned sbt, Scala-CLI, and mill all take advantage of Bloop. The end-users might not even be aware that they are using Bloop, as typically it’s not something that they interact with directly.
The right developer experience tools give your team a chance to be more productive, which in the long run saves money and resources.
Getting a developer environment up and running, making it efficient, and keeping it useful to your engineers is something most companies struggle with. With the right tools, your team will be able to spend time coding and solving actual problems instead of fruitlessly waiting or debugging their IDEs or build tools.
When working for our clients, we focus on improving the compilation time and making sure that their tools work properly. That is why, when selecting a Developer Experience (DX) tool, there are a few factors that our engineers always consider.
- Integration with existing tools: A new tool should fit well within the existing ecosystem of tools and workflows so that it can leverage and complement the features of our clients' current stack. This reduces the learning curve and potential disruption to the project.
- Usability: A good developer experience tool should be easy to learn and come with a user-friendly interface and design. Good usability is also about good documentation, accessible support, and a smooth overall user experience of the tool.
- Performance improvements: A good tool should provide faster execution times, better resource management, or more intelligent features like code completion and error detection. Tools that enhance performance can lead to quicker iteration cycles, allowing teams to develop, test, and deploy software more rapidly.
- Cost reduction: We are also paying attention if the tool reduces costs. There are different ways it can do it, for example, it can be through its pricing model or by allowing developers to work more efficiently.
