The Scala programming language is an open source project with a very diverse community, where people from all over the world contribute their work, with everyone benefiting from friendly help and advice, and kindly helping others in return. So why not join the Scala community and help everyone make things better?

Tools and Libraries

The Scala ecosystem includes a great many diverse open-source projects with their own maintainers and community of contributors. Helping out one of these projects is another way to help Scala. Consider lending on a hand on a project you’re already using. Or, to find out about other projects, see the Libraries and Tools section on our Community page.

Scala Community Build

The Scala community build enables the Scala compiler team to build and test a corpus of Scala open source projects against development versions of the Scala compiler and standard library in order to discover regressions prior to releases. The build uses Lightbend’s dbuild tool, which leverages sbt.

If you’re the maintainer – or just an interested user! – of an open-source Scala library or tool, please visit the community build documentation for guidelines on what projects are suitable for the community build and how projects can be added.
