Scala developers looking for some great open source libraries can go to the excellent Awesome-Scala List or the newly created Scaladex.
However, it is very often useful to look at ready-made products to make your Scala coding even more amazing. Here is a list of products you should use, or at least take a serious look at:
1. SamebugβββExceptions Database with Solutions

Samebug is the smartest way to debug your Scala exceptions. Samebug is a collection of over 200,000 solutions to exceptions. Samebug uses stack trace analysis to find the most relevant solutions to your exceptions.
It recently released an integration with IntelliJ which makes it even more useful.
2. IntelliJβββIDE

No need to introduce IntelliJ from Jetbrains. Without wanting to enter in a cat-fight, IntelliJ is the IDE of choice at Codacy. The Scala support is really excellent.
3. TakipiβββError Monitoring
Takipi detects every production issue in your app and helps you prioritize and fix those issues. It supports all JVM languages and the installation process is really smooth. We particularly like the numerous integrations with Datadog, New Relic, Slack, etc.
4. CodacyβββAutomated CodeΒ Reviews
Of course, we are biased on this one, but Codacy is the best static analysis and automated code review tool for Scala. From security issues to Scala best practices, Codacy will catch new issues automatically in your commits and pull request so that developers can save hours in code reviews and merge with confidence.
5. CodeshipβββContinuous Integration

Using modern continuous integration tools will help you deliver hassle-free the best product possible to your users. Codeship has a great JVM support and the new Codeship Pro makes it really easy to combine it with Docker.
6. New RelicβββApplication Performance Monitoring

Its ease of installation and great JVM support makes it a must have for Scala developers. Its Lightbend partnership can get you a free Lite account if you register here.

Edit: We just published an ebook: βThe Ultimate Guide to Code Reviewβ based on a survey of 680+ developers. Enjoy!
