A community driven list of useful Scala libraries, frameworks and software. This is not a catalog of all the libraries, just a starting point for your explorations. Inspired by awesome-python. Other amazingly awesome lists can be found in the awesome-awesomeness list.
Also awesome is Scaladex, the searchable, tagged, and centralized index of Scala libraries.
Projects with over 500 stargazers are in bold.
Your contributions are always welcome! Please submit a pull request or create an issue to add a new framework, library or software to the list. Do not submit a project that hasn’t been updated in the past 6 months or is not awesome.
