Awesome Scala 
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.
Contributing
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.
Don't modify README.md in your pull request. It is automatically generated. Modify template.md instead.
