Bloop is a Scala command-line tool and build server developed at the Scala Center to make the compile and test feedback loop as tight as possible, with a focus on developer productivity.

Tight feedback loop

Edit, compile and test workflows are the bread and butter of our daily jobs. When our build is slow to respond, our productivity drops. Bloop is a command-line tool and build server that brings you a tighter developer workflow. Slow Scala compile times can often be attributed to the slugishness of our build tool, and bloop aims to address them.

We have created bloop to make you productive without getting in your way. We focus on how you can be faster at writing Scala code using your current build tool, whether it’s sbt, Maven or Gradle.


Bloop's documentation lives in our website.

  1. User documentation to read about the project, how to install and use bloop, and similar user inquiries.
  2. Developer documentation to learn how to hack on the project, run our community build, improve documentation, etc.
